If the idea of washing period underwear makes you a little squeamish, you're in good company. It's the number one thing that stops people trying it in the first place: the worry that it'll be gross, complicated, or somehow ruin the rest of your laundry. Here's the honest truth after you've done it once: it's easier than rinsing a coffee cup, and it's every bit as hygienic as washing anything else. This is the complete guide to washing period underwear the right way, so it stays fresh, keeps working, and lasts for years. The exact steps, why each one matters, and the mistakes worth avoiding. The quick version Rinse in cold water until it runs clear, then cold machine wash in a mesh bag with a mild detergent. Skip the fabric softener and bleach, and air dry instead of using the dryer. That's the whole routine. Everything below is just the why, and the few details that make your pairs last longer. How to wash period underwear, step by step Step 1: Rinse in cold water first As soon as you take a pair off, give it a quick rinse under cold running water, gently pressing the gusset until the water runs clear. This lifts most of the blood out before it has a chance to dry in. Plenty of people just do this in the shower, which is honestly the easiest way to fit it into your day. Cold is the key word. Warm or hot water sets a blood stain instead of removing it, because heat cooks the proteins in blood the same way it turns an egg white opaque. So keep it cold, every time. On a lighter day you can sometimes skip straight to the wash, but on a heavier day the cold rinse is what keeps stains and smells from setting in. Step 2: Cold machine wash in a mesh bag Pop your rinsed pairs into a mesh laundry bag and run them through a cold, gentle cycle with a mild detergent. The mesh bag stops them tangling, stretching, or catching on zips and hooks from the rest of your load. Cold water protects both the fabric and the built-in layers that do the work, which brings us to the one thing that matters most. Step 3: No fabric softener, no bleach This is the mistake almost everyone makes, so it's worth saying plainly. Never use fabric softener on period underwear. Softener works by leaving a thin, waxy coating on the fibres to make them feel soft, and on a normal pair of socks that's harmless. On period underwear, that coating seals up the absorbent layer so liquid can't pass through it anymore, which quietly kills the absorbency and traps odours in. It's the reason a lot of people find their pairs stop working or start to smell, and it's largely permanent once it happens. Bleach is out for the same reason it's out on anything you love: it breaks the fibres down. Mild detergent, nothing else. Step 4: Air dry, never the dryer Hang them up or lay them flat somewhere with a bit of airflow, and let them dry fully. High heat from a dryer is hard on the waterproof layer and the elastic, and it's the fastest way to shorten a pair's life. If you're in a hurry, press them in a clean towel to pull out the extra water rather than wringing them, then let them finish in the air. Just make sure they're completely dry before they go back in the drawer, since any leftover damp is what causes that musty smell. That's it. For our own pairs, the care is exactly this: cold machine wash in a mesh bag, no fabric softener, air dry. Do you have to rinse before washing? On a heavier day, yes, the cold rinse is worth the thirty seconds. It pulls out most of the blood so nothing sets in the wash, and it's the single best thing you can do to prevent stains and keep pairs smelling fresh. On a light or just-in-case day, when there's barely anything to rinse, you can put them straight into a cold wash and they'll come out perfectly clean. Use your judgement, there's no rule that every pair needs a rinse. Why does my period underwear smell after washing? If a pair still smells once it's clean and dry, it's almost never the underwear itself. Fresh menstrual blood barely has a scent. A lingering smell after washing usually comes down to one of a few fixable things: Fabric softener or detergent build-up. The most common culprit. That waxy residue traps odour. Stop the softener, use a little less detergent, and run an extra rinse. Not rinsing enough first. Blood left deep in the absorbent layer feeds bacteria. A proper cold rinse until the water runs clear fixes it. Not drying fully. Damp left in the fabric turns musty. Air them somewhere with good airflow until bone dry. If a smell has already built up, soak the pairs in one part white vinegar to three parts cold water for about fifteen to thirty minutes, then wash cold as usual with no softener. The vinegar cuts through the residue and resets the fabric. One honest note: if you're noticing a strong odour coming from your body rather than from clean underwear, that's a different thing worth mentioning to your doctor. This is general information, not medical advice. Can you wash period underwear with the rest of your laundry? Yes. Once a pair has been rinsed until the water runs clear, it's perfectly hygienic to wash it in a cold load with everything else, and it won't stain your other clothes or your machine. A washing machine dilutes everything almost instantly, and cold water keeps anything from setting. That said, plenty of people still prefer to use a mesh bag or run a separate load, just for peace of mind or to be a little gentler on the fabric. Both are completely fine. There's no hygiene reason you have to keep them separate, so do whatever makes you comfortable. How long does period underwear last? With good care, a pair generally lasts somewhere between six months and a couple of years, and how you wash it makes most of the difference. Cold water, no softener, and air drying are what protect the absorbent and waterproof layers over time. The pairs that wear out early are almost always the ones that went through a hot dryer or picked up softener residue. Replace a pair when you notice it's not holding like it used to, the elastic has gone, or a smell won't shift no matter how you wash it. Compared with reaching for disposables every cycle, a few well-cared-for pairs go a long way, which is part of the appeal. A note on soft fabric The same gentle routine that protects the working layers also keeps the fabric feeling good. Our period range is made from soft modal, which stays buttery against the skin when it's washed cold and air dried, and loses that softness fast if it's put through high heat. So the care that makes your pairs last is the same care that keeps them feeling nice to put on. If you're looking for a pair to start with, our Period Boxer Briefs have a full built-in absorbency panel, and you can see the whole period and leakproof range in sizes XS to 5XL. Frequently asked questions How do you wash period underwear? Rinse in cold water until it runs clear, then cold machine wash in a mesh bag with a mild detergent. Skip fabric softener and bleach, and air dry rather than using the dryer. Do you have to rinse period underwear before washing? On heavier days, yes, a quick cold rinse until the water runs clear prevents stains and odour. On light days you can usually put them straight into a cold wash. Can you machine wash period underwear? Yes. Use a cold, gentle cycle with mild detergent, ideally in a mesh bag to protect the fabric. Hand washing works too if you prefer, but it isn't necessary. Can you put period underwear in the dryer? It's best to air dry. High heat can damage the waterproof layer and the elastic and shorten the life of a pair. Air drying keeps them working and feeling soft for longer. Can you use fabric softener on period underwear? No. Fabric softener leaves a waxy coating that clogs the absorbent layer, reduces absorbency, and traps odour. Use mild detergent only, with no softener, dryer sheets, or bleach. Why does my period underwear smell after washing? Usually it's fabric-softener build-up, not rinsing enough first, or not drying fully. Stop using softener, rinse until the water runs clear, soak occasionally in one part white vinegar to three parts cold water, and let them air dry completely. Is it hygienic to wash period underwear with other clothes? Yes, once rinsed, washing them in a cold load with everything else is perfectly hygienic and won't stain your other clothes or your machine. Many people still prefer a mesh bag or separate load, which is fine too. How often should you replace period underwear? With good care, most pairs last from six months to a couple of years. Replace them when the absorbency drops off, the elastic wears out, or a smell won't wash out. Shop period & leakproof  

It's the first proper warm day. You put on the dress, you feel great, you walk out the door. Twenty minutes later your inner thighs are on fire, and by the time you're home there's an angry red patch where skin met skin all afternoon. If you know, you know. This is chub rub, and it's one of the most common, least talked-about parts of warm-weather life. Here's the good news: it's very fixable, and you don't have to hide your legs to fix it. This is the honest, complete guide, every real solution laid out with the pros and cons, not just a list of things to buy. What is chub rub, really? Chub rub is the friendly, slightly cheeky name for inner-thigh chafing: the skin irritation you get when your thighs rub against each other, over and over, usually in heat and humidity. Dermatology sources describe chafing as exactly that, skin rubbing against skin or clothing in warm, damp areas like the inner thighs, groin, underarms and under the bust. Sweat, heat and movement all make it worse. It usually shows up as redness, a stinging or burning feeling, and sometimes a raw patch or rash. When it gets more severe, or keeps happening in the same warm, moist fold of skin, it can develop into what doctors call intertrigo, an inflammation of the skin folds that can sometimes get irritated further by yeast or bacteria. Most mild chub rub calms down within a day or two once the rubbing stops, but if it keeps coming back, that's worth paying attention to. Why do my thighs chafe? (And why it's not about your weight) This is the myth worth busting first, because it keeps people quietly embarrassed for no reason. Chub rub is not a plus-size problem. Whether your thighs touch comes down to the width of your hips and the structure of your pelvis, not the number on the scale. That's why slim women get chub rub. Runners get it. Athletes with strong, muscular thighs get it, sometimes more, because muscle increases the contact. If your thighs touch when you walk, you can chafe, and most people's thighs touch. So if you've been carrying a bit of shame about this, put it down. It's friction, it's physics, and it's incredibly common. Every way to stop chub rub, honestly reviewed There's no single right answer, because it depends on what you're wearing and how your day looks. Here's the honest rundown. Long-leg underwear and bike shorts This is the most reliable all-day fix, because it puts a smooth layer between your thighs so skin never touches skin in the first place. Unlike a balm, it doesn't sweat off or need reapplying halfway through the day. The catch is that a lot of bike shorts are thick, hot, or roll up as you walk, which defeats the point. The trick is a thin, breathable pair with a leg that actually reaches where your thighs touch and a hem that stays put. More on how to choose below. Shop the 5″ boxer (XS–5XL) Anti-chafe balms and sticks A glide stick or balm (the drugstore favourites like Body Glide and Megababe Thigh Rescue) creates a slippery barrier right on the skin. It's invisible, it works under any outfit, and it's easy to carry. The downside is that it can sweat off on a hot day, needs reapplying, and can melt or feel greasy. Great for minimal outfits where you don't want an extra layer, less reliable for a long, sweaty day on your feet. Powders and gels Powders (cornstarch-based ones rather than talc) absorb moisture and cut friction, which helps because damp skin chafes faster. Anti-chafe gels do a similar job to balms but tend to dry clearer and resist sweat a little better. Both need reapplying, and powder can get messy or cake up. Thigh bands Fabric or lace bands that sit around each thigh (Bandelettes are the best known) are a discreet alternative to shorts. They work well for some people, but the common complaint is that they slide down or roll as you move, so fit matters a lot. Staying dry Not a barrier on its own, but it helps everything else work: breathable fabrics, changing out of damp clothes, and avoiding cotton (which holds sweat against the skin) all reduce how fast you chafe. Think of it as the base layer of any chub-rub plan. Most people land on a combination. The honest takeaway: for a long, active, hot day, a good pair of long-leg underwear is the most dependable option, and a balm is a great backup for outfits where you'd rather not layer. How to choose anti-chafing shorts that actually stay put If you go the underwear route, the difference between "life-changing" and "back in the drawer" is in the details. Here's what actually matters. Length that reaches where your thighs touch. This is the whole game. A short cut leaves your thighs meeting below the hem, so the chafing just moves down. For most people that means a 5″ or 8″ inseam. The longer the leg, the more reliably skin stays off skin. A leg band that grips without rolling. The number-one complaint about anti-chafe shorts is that they ride up. A flat, bonded hem (rather than a thick stitched one) tends to stay lower on the thigh and won't dig in or leave marks. Breathable, moisture-managing fabric. Since heat and sweat are what start the problem, you want something that breathes and dries fast, not a thick compression short that traps heat. Modal, for example, is more breathable than cotton and dries faster, so it stays comfortable in humidity. Smooth and no-VPL under dresses. A seamless pair in a nude or skin tone should be invisible under a summer dress, so you get the protection with none of the "are those showing?" worry. Size-inclusive. Since chub rub affects every body, the range should too. Shop the 8″ Biker This is exactly where our longer styles fit in. The 8″ Biker gives the most thigh coverage of anything we make, in a thin, breathable modal with a flat, hot-pressed hem that's designed to stay down instead of rolling up. For a shorter, lighter option that still clears most thighs, the 5″ boxer brief runs all the way to 5XL. One customer put it better than we could: "I've long been a curvy girl who wants to wear dresses, but the chub rub can get real!", and another said the 8″ "literally feel like you are wearing nothing... especially if you have larger thighs." How to heal chafed thighs (and when to see a doctor) If the damage is already done, stop the friction first, that's what lets the skin settle. Keep the area clean and dry, and give it a rest from whatever caused it. Dermatologists at the American Academy of Dermatology note that a thin layer of petroleum jelly can help protect and soothe irritated skin while it recovers. Mild chafing usually calms down within a day or two. See a doctor or dermatologist if the skin breaks, oozes, blisters, spreads, or hasn't improved after a week or so, or if it comes with a fever, since that can signal an infection that needs treatment. This is general information, not medical advice, so if something doesn't look right, get it checked. Surviving chub rub season Summer is peak chub rub season: heat, humidity, dresses, weddings, festivals, long days walking around on vacation. The freeing part is realising you don't have to choose between comfort and wearing what you want. A thin pair of long-leg underwear under a sundress, a balm in your bag for touch-ups, and staying dry where you can, and the thing that used to ruin your afternoon just stops being a problem. Frequently asked questions What is chub rub? Chub rub is a casual, body-positive term for inner-thigh chafing: skin-on-skin friction that leaves your thighs red, stinging or raw, usually in heat and humidity. Does thigh chafing only happen to plus-size people? No. Whether your thighs touch comes down to your hip and pelvic structure, not your weight. Slim women, runners and athletes chafe too. If your thighs touch, you can get chub rub, and most people's do. How do I stop my thighs from rubbing together? Put a barrier between them. Long-leg underwear or bike shorts are the most reliable all-day option, an anti-chafe balm works for minimal outfits, and keeping skin dry with breathable fabric helps everything work better. What length should anti-chafing shorts be? Long enough to reach where your thighs actually touch, which for most people is a 5″ or 8″ inseam, with a leg band that won't roll up. A cut that's too short just moves the chafing lower. How long does chafed skin take to heal? Usually a day or two once the friction stops. More severe chafing can take up to a week or two. See a doctor if it blisters, oozes, spreads, or won't heal. Do anti-chafing shorts show under dresses? Not if they're seamless with a flat, bonded hem and in a nude or skin tone. A thin pair should be invisible under a dress, with no visible panty line. Are balms or shorts better for chub rub? Shorts are the most reliable all-day barrier since they don't sweat off. Balms are great for outfits where you don't want a layer, but they need reapplying. Plenty of people use both. What fabric is best to prevent chafing? Breathable, moisture-managing fabrics like modal, which is more breathable than cotton and dries faster. Avoid cotton on hot days, since it holds sweat against the skin. Shop anti-chafing shorts  

Let's talk about the underwear you never actually reach for. You know the one, shoved to the back of the drawer, only worn on laundry-emergency days. It rides up. It digs in. It goes see-through under leggings by lunchtime. Somehow, it's just... fine. We think "fine" is a pretty low bar for something you wear every single day. Most underwear is designed around broad averages and how efficiently it can be produced, not around how it actually feels on a real body, living a real life. So when we started Pure Snug, we asked a nosier question: what would make a woman genuinely excited to reach for the same pair again tomorrow? That question shaped everything, from the fabric to the women's-specific patterns, the inseam options, the gusset choices, the smooth finishes, and yes, those prints people can't stop collecting. Here's what we believe makes underwear genuinely great. The short version Great underwear should feel soft, stay exactly where you put it, and work with your body, your clothes and your day, not against them. We combine premium modal with women's-specific patterns, three inseam lengths, tapered leg openings, flexible gusset options and sizes from XS to 5XL. The goal is simple: underwear you forget you're wearing, and remember the moment it's time to get dressed. 1. Fabric: not all "soft" feels the same "Soft" and "breathable" get printed on just about every underwear label out there, but the fibre, the knit and the finishing all quietly decide how a fabric actually feels against your skin. We use premium modal, a regenerated cellulose fibre made from responsibly sourced beech wood. Modal is produced in a resource-efficient process with high recovery rates of the chemicals involved, and what lands on your skin is smooth, breathable, and naturally good at absorbing and releasing moisture, so it feels drier against the body through a long day. Our fabric is also tested to OEKO-TEX® STANDARD 100, Product Class I, the standard's strictest product class, which sets the lowest limit values for harmful substances and is the class applied to textiles for babies and toddlers. To be fully upfront: this doesn't mean "chemical-free", and it isn't an organic or environmental certification. What it means is independent, third-party lab testing of the finished fabric against a genuinely strict limit for harmful substances, checked and renewed each year, not just a nice word on a swing tag. The result, for everyday wear, is a light, silky feel with real stretch and shape retention, without needing a heavy, bulky fabric to get there. Shop the 3″ boyleg 2. Fit engineering: designed around women's bodies Comfort isn't fabric alone. A pair can feel beautifully soft in your hand and still bunch, ride up, or demand constant adjusting if the pattern was never built for how your body actually moves. Our patterns are developed specifically for women, not resized from a unisex block. Waistband placement, gusset shape, leg taper, inseam length and coverage are all considered together, then refined through real customer feedback. That's what we mean when we say thoughtfully engineered to stay put. Tapered leg openings that actually follow your thigh A straight leg opening leaves excess fabric bunching in one spot and pressure digging into another. Our tapered leg shape follows the natural line of the thigh more closely, so the fabric sits snugly with less bunching and far fewer mid-day tugs. If you've been hunting for women's boxer briefs that don't ride up, or comfortable underwear for fuller thighs, this one small pattern detail tends to make a surprisingly big difference. Three lengths, because no two days (or bodies) are the same Bodies, outfits and comfort needs all vary, so we make three lengths. The 3″ boyleg is lighter, shorter coverage designed to sit smoothly under fitted pants and leggings. The 5″ boxer is the everyday all-rounder, with balanced coverage and thigh comfort. The 8″ biker is longer coverage for dresses, no ride up, anti-chafing comfort, or anyone who wants more fabric through the thigh. Gusset options built for real life Different needs call for different construction, so we don't force a single gusset on everyone. Our standard styles feature an attached gusset, while our PadStay collection uses a floating organic cotton gusset, designed to make it easier for the wings of many pads to wrap around securely. Gusset type varies by style, so it's always worth checking the individual product page. 3. Construction: the details you feel after hours of wear The very best construction details are usually the ones you never notice at all. We focus on cutting bulk, rubbing and visible ridges, while keeping every style secure and genuinely wearable. Smooth waistbands and hems Selected styles use heat-bonded waistbands and hems for a flatter finish under leggings, fitted pants and anything close-fitting, helping cut down on bulky edges and visible lines. Other styles use stitched finishes where that construction suits the garment best. Check the product page for style-specific details. Fewer pressure points where you sit Most of our styles skip the centre-back seam, so there's no raised ridge running through the exact spot you sit on all day. The result is a smoother feel with fewer pressure points, whether you're travelling, at a desk, or just living your life. Sizing from XS to 5XL Our range runs from XS to 5XL. Inclusive sizing isn't just about stretching a size chart, it takes real pattern grading and fit decisions to preserve the intended coverage, leg shape and comfort across every single size. Always check the current size guide, since fit is personal and varies with body shape and preference. 4. Prints designed to be collected This might be our favourite difference to talk about, honestly, because it's the one most brands skip entirely. A lot of "cute print" underwear is built from cheap, mass-produced stock patterns, the kind of small repeating tile you'll spot on a dozen unrelated products. It's fine. It's also completely forgettable. Picture your desktop printer printing a photo onto a sheet of paper, then scale that up to a giant textile printer running continuously across metres of fabric. That's essentially how our digital prints are made: the artwork is printed straight onto the fabric roll before it's cut and sewn into your Snugs. More traditional printing methods are often built for large production runs, where simpler repeating patterns and flatter colours are more practical. Digital printing gives us the freedom to play with intricate detail, colour gradients, more complex artwork and smaller batches. That's how flamingos, Wild Jungle, cherries, birds and all our other slightly-too-fun ideas make their way onto your underwear, with a richer, more detailed finish that genuinely feels like wearable art. Some of our customers properly collect our prints, the way other people collect scarves or sneakers. That's not an accident, it's kind of the whole point. Shop the printed boxers 5. Built through real customer conversations We keep refining fit and construction based on the people who actually wear it. Our length options, expanded sizing, gusset variations and evolving finishes all come from one practical idea: comfortable women's underwear should work for real bodies and real routines, not ask women to work around the garment. Is Pure Snug "better" than every other brand? Honestly? Fit is personal, and no single pair is going to be perfect for every body, we're not going to pretend otherwise. What we can promise is intent: our fabric, patterns, length choices, gussets, finishes, sizing and prints are all deliberate decisions, shaped around real women's comfort, not just around what's cheapest to mass-produce. If you've spent years bouncing between brands, wondering why underwear just won't stay put, the problem probably isn't your body. It might simply be that the garment was never designed for the way you move, sit, walk and live. Trying a new underwear brand can feel like a bit of a leap of faith. Our Love at First Snug Guarantee is designed to make that first-pair decision easier: if your first pair isn't right, get in touch and our team will help sort it out. Full eligibility and conditions are on our website. Frequently asked questions What fabric does Pure Snug use? Premium modal, a regenerated cellulose fibre made from responsibly sourced beech wood. It's soft, breathable and naturally moisture-managing, and it's tested to OEKO-TEX® STANDARD 100, Product Class I, the strictest product class of that certification. Is modal good for hot weather? Its smooth, breathable feel and the way it absorbs and releases moisture can make it a genuinely comfortable choice in warm weather, though comfort still depends on fit, activity and personal preference. Does Pure Snug make anti-chafing underwear? The 8″ biker offers the longest thigh coverage and is our go-to recommendation when you want extra help reducing skin-on-skin friction, whether that's under a dress or just through a busy day. What does "printed by the metre" mean? Think of a desktop printer printing onto paper, scaled up to a giant textile printer running continuously across metres of fabric. The artwork is printed straight onto the fabric roll before it's cut and sewn. Unlike traditional methods built for simple repeating patterns, digital printing lets us play with intricate detail, colour gradients and smaller batches, which is how we get all those detailed, collectable prints. What sizes does Pure Snug offer? XS through 5XL. Use the current size guide, and factor in how snug you personally like things to sit. What's the difference between a floating and attached gusset? A floating gusset is secured at the ends but open along the sides, which makes it easier to wrap pad wings around. An attached gusset is built in flat all the way around. Gusset type varies by style, so it's always worth checking the product page. Which inseam length should I choose? Go for the 3″ boyleg for shorter, lighter coverage, the 5″ boxer for everyday versatility, or the 8″ biker for longer coverage and extra thigh comfort. Your height, thigh shape, outfit and coverage preference can all steer the decision. Will Pure Snug show under leggings? Selected styles use flat, heat-bonded waistbands and hems designed to reduce bulk and visible lines. Results can vary with garment colour, fabric thickness, fit, and the leggings you're wearing. Find your snug  

If you've shopped for underwear lately, you've seen these three words everywhere: bamboo, modal, cotton. All three get sold as "soft", "breathable" and "sustainable", and honestly the labels start to blur. We get asked about this a lot, so here's the proper breakdown: what these fabrics actually are, how they're made, and which one makes sense for underwear. Spoiler: it isn't simply "bamboo is natural, so bamboo wins". It's more interesting than that. First, a myth-buster: "bamboo fabric" usually isn't just bamboo This is the part that trips most people up. When you read "bamboo" on a clothing label, you probably picture the plant being turned into thread. That's not what's happening. Bamboo is a woody grass, and raw bamboo fibre (the mechanically processed kind, sometimes called bamboo linen) is coarse, closer to linen than to the silky fabric you've felt on clothing. To get that soft, drapey feel, manufacturers dissolve bamboo pulp in chemicals and re-spin it into fibre. That process is called viscose, or rayon, and the conventional version typically uses sodium hydroxide and carbon disulfide, chemicals that can pollute air and waterways if they aren't properly recovered and treated. So most "bamboo" underwear on the market is technically bamboo viscose, not bamboo in any raw sense. This isn't a fringe complaint. In the US, the Federal Trade Commission has taken repeated action over it, with retailers agreeing to civil penalties totalling roughly 1.26 million dollars in 2013, 1.3 million in 2015, and 5.5 million in 2022 (that last one involving Kohl's and Walmart). The FTC's position is simple: once bamboo is chemically processed, the finished fibre is rayon, so it has to be labelled "rayon" or "rayon made from bamboo", not just "bamboo". The FTC has also separately challenged "antibacterial" and "eco-friendly" bamboo claims as unproven. None of this makes bamboo viscose bad to wear. It's soft, it breathes, and plenty of people love it. But if sustainability is the reason you're reaching for it, the word "bamboo" alone doesn't tell you much about how it was actually made. So what is modal, exactly? Modal is also a regenerated cellulose fibre, meaning it goes through a dissolve-and-respin process like bamboo viscose, but it's made from beech tree pulp, and the better versions are made under much tighter environmental controls. The name you'll see most is TENCEL™ Modal, made by the Austrian company Lenzing. Here's a distinction worth getting right, because a lot of articles get it wrong. You may have read that "modal recovers over 99% of its solvents in a closed loop". That famous figure actually belongs to TENCEL™ Lyocell, a different fibre made with a non-toxic solvent in a genuinely closed loop. TENCEL Modal is made with a modified viscose process instead: cleaner than generic viscose, using oxygen-based bleaching and recovering a high share of its process chemicals (Lenzing has cited around 95%), but it isn't the same near-zero-waste loop as Lyocell. The honest short version: TENCEL Modal is a cleaner, more transparent modal than the generic kind, with real numbers behind it, rather than a miracle fabric. Beech trees are also low-maintenance to grow. They're largely sourced from managed forests in Central Europe and don't need irrigation or replanting the way many crops do. Shop the loungewear On feel, modal is one of the softest apparel fibres there is: smoother and silkier than cotton, with a bit more stretch. It's also good at moisture: it absorbs sweat and releases it into the air faster than cotton, so it feels drier and cooler against the skin rather than staying damp. That matters a lot for something worn against your body all day. And cotton, the fabric everyone already knows Cotton barely needs an introduction, but it's worth remembering it's a completely different category. It's a natural fibre, harvested from the cotton plant and spun straight into thread, with no chemical dissolving step. That simplicity is part of why cotton has been a wardrobe staple for so long. Shop the 3″ boyleg briefs Cotton is breathable, gentle on sensitive skin and widely considered hypoallergenic, which is why it's stayed a go-to for underwear. Its trade-off shows up with moisture: cotton absorbs sweat but holds onto it, so on hot or active days it can stay damp longer than modal, which releases moisture faster. Cotton also tends to lose its shape and softness a bit faster over many washes, where modal resists pilling and stretching better. On the environmental side, cotton is genuinely resource-heavy. WWF estimates it takes around 2,700 litres of water to produce a single cotton t-shirt, roughly what one person drinks in about two and a half years. Beech, the raw material for modal, needs no irrigation and far less water. Organic cotton improves on the chemical side, but it's still a thirstier crop than beech. Putting it side by side Feel. Modal tends to win, silkier and smoother than both cotton and bamboo viscose, though good bamboo viscose comes close. Breathability and moisture. All three breathe reasonably well, but modal moves moisture away and dries faster, rather than just absorbing and holding it like cotton. Durability. Modal holds its shape and resists pilling better than cotton over time. Cotton tends to thin out and lose structure faster with repeated washing. Sustainability. The most nuanced one. Beech for modal needs very little water or land management, and the better modal processes recover most of their chemicals. Bamboo as a raw crop is fast-growing and low-input, but bamboo viscose processing is often not closed-loop, so a lot of that raw sustainability gets undone in manufacturing. Cotton is the most water and land intensive of the three, especially when it isn't organic. Everyday comfort for underwear. This is where modal has the edge, because the combination of softness, faster-drying comfort and shape retention matters more for something worn against skin all day than it does for a t-shirt. Why this matters for what you're wearing We're not here to tell you cotton is bad or bamboo viscose is a scam. Both are perfectly reasonable choices, and plenty of great underwear is made from each. But "natural", "eco" and "bamboo" get thrown around so loosely in fashion marketing that it's genuinely hard to know what you're buying without digging in. Shop the 5″ boxer briefs That's a big part of why we make our undies from modal spun from sustainably sourced beechwood. It's not just the softness, although yes, it's extremely soft. It's that beech is a low-water, renewable source, and modal gives you that silky, faster-drying, holds-its-shape comfort that works so well against skin all day. If you've been choosing fabrics by which label sounds the most "natural", it might be worth choosing by what's actually happening in the supply chain instead. Sometimes the more processed option is the more transparent one. You'll find the same beechwood modal across the range, from our 3″ boyleg briefs and 5″ boxer briefs to the 8″ biker shorts and our loungewear. Prefer classic cotton? We make that too. Frequently asked questions Is bamboo underwear actually made from bamboo? Technically yes, but not the way most people picture. The bamboo plant is dissolved into pulp and chemically re-spun into fibre, a process called viscose. So bamboo is the raw material, but what ends up on your body is rayon, made the same way as most rayon fabrics. The FTC has taken action against brands for labelling this simply "bamboo" rather than "rayon made from bamboo". Is modal natural or synthetic? Neither exactly, it sits in between. Modal starts from a natural, plant-based source (beech pulp) but goes through chemical processing to become fibre, which is why it's classed as semi-synthetic, or "regenerated cellulose". It isn't petroleum-based like polyester or nylon, but it isn't a raw natural fibre like cotton either. Is modal better than cotton? It depends what you're optimising for. Modal generally wins on softness, faster-drying comfort and holding its shape over time, resisting pilling and stretching better than cotton. Cotton wins on simplicity, since it's a raw fibre with no chemical processing, and it's a safe choice for sensitive skin. For underwear worn all day or on active days, most people find modal the more comfortable option. Does modal shrink? Not easily. Modal is more shrink-resistant than cotton, but it isn't shrink-proof. High heat, hot water or a hot dryer, is the main culprit, so wash cold and air dry or tumble on low to keep it looking new. Is modal biodegradable? The fibre is. TENCEL™ Modal is certified by TÜV Austria as biodegradable and compostable, since it's made from cellulose rather than plastic-based fibres. One thing to know: most underwear is blended with a little elastane for stretch, and that blend won't fully biodegrade the way 100% modal would. Why does modal feel cooler than cotton? It comes down to how each fabric handles moisture. Cotton absorbs sweat and holds onto it, which can feel damp. Modal absorbs moisture too but releases it into the air faster, so it feels drier and cooler even when you're warm. That's part of why it's such a popular choice for underwear. Feel the difference  

Turn a pair of undies inside out and you'll find it: a separate little panel of fabric sewn into the crotch, usually a softer, plainer material than the rest. A surprising number of people think it's a pocket, and every so often someone asks what they're supposed to keep in there. The answer is nothing. That panel is the gusset, and once you know what it's doing, you start to care quite a lot about how it's made. It turns out there's more than one way to build one. We make two, and the difference between them decides whether your pad stays put or wanders off halfway through the day. So it's worth two minutes to understand. What is a gusset, and why is it there? A gusset is an extra piece of fabric set into the crotch of your undies. The dictionary calls it an insert added to a seam "to provide expansion or reinforcement," which is a dry way of describing something that genuinely makes your underwear better to wear. The crotch is the narrowest part of the garment and the part that moves and stretches the most, so instead of forcing a single seam to cope with all of that, the gusset spreads the load across a whole extra panel. That gives you room to move, takes the strain off the stitching so the undies last longer, and lays a soft layer against the most sensitive skin on your body. It's an old idea. The word "gusset" started out as an armour term, the piece of chain mail that protected a knight's armpit, and only crossed over into clothing in the 1500s. The job has stayed the same for five hundred years: put stretch and strength exactly where the body needs it most. And no, the open edge you can sometimes lift isn't a pocket. It's left unstitched on one side purely to hide the seams during manufacturing. Handy to know before you try to tuck anything in there. Why is the gusset almost always cotton? This is the part worth paying attention to, because it's about comfort and health, not just construction. Cotton breathes and pulls moisture away from the skin, so even when the outer fabric of your undies is something smoother and stretchier, the layer actually touching you stays cooler and drier. That matters most in exactly the warm, humid conditions where things get uncomfortable. Australian health bodies land on the same advice. Jean Hailes recommends "natural fibre underwear, such as cotton," and Australia's healthdirect points to breathable, natural fabrics for the same reason. Gynaecologists at the Cleveland Clinic put it more bluntly: cotton "wicks away excess sweat and moisture that bacteria and yeast thrive on." Ours is organic cotton, grown without harsh pesticides and finished with fewer chemical residues, which is the gentler choice if your skin reacts easily. It's a small detail that sits against you all day, so we'd rather get it right. This is general information, not medical advice. If something doesn't feel right, see your GP. Attached vs floating: the two kinds we make Here's where the two-minute lesson pays off. Every gusset is sewn in, but how it's sewn in changes what the undies can do. An attached gusset is the traditional one, and it's what most of our styles have. It's stitched down flat all the way around, so it lies smooth and disappears under your clothes. There's nothing to think about: it's comfortable, it's clean, and it's perfect for everyday wear, panty liners and regular pads. If you're not layering a winged pad over the top, this is all you need. A floating gusset is built differently on purpose. It's stitched at the front and the back, but left open along both sides, and that open edge is the entire point. The wings of a pad tuck up underneath it, so the pad is gripped from both sides instead of clinging on by its sticky strip alone. It holds a winged disposable pad, a liner, or a reusable cloth pad exactly where you put it, through walking, sitting, and a full night's sleep, without shifting, folding or bunching. This is our PadStay range. One thing trips people up, so it's worth saying plainly: a floating gusset doesn't absorb anything by itself. It holds your pad, it doesn't replace it. If what you actually want is protection built in, with no pad at all, that's a different product, our period and leakproof range, which absorbs on its own. If you love your pads and just want them to stay put, that's PadStay. So which one is right for you? It comes down to how you actually use them, and for most people the answer is quick. If you wear undies for everyday, reach for a liner now and then, or use a regular pad without wings, the attached gusset is the easy pick. Smooth, simple, no fuss, and it's already on most of our range. If you use pads with wings, or you've switched to reusable cloth pads to cut down on waste, the floating gusset is the one that will change your day. Cloth pads especially have no adhesive to rely on, so a gusset that physically holds them is the difference between a pad that stays and a pad that slides. That's what PadStay is for. Every PadStay style already comes with an organic cotton floating gusset. We're bringing the rest of our range over to organic cotton as well, so in time every pair will work beautifully with liners and pads of every kind. The little things add up The gusset is one of those details you never notice until it's wrong: the pad that won't sit still, the panel that feels sweaty, the seam that rubs. Get it right and you simply stop thinking about it, which is exactly how good underwear should feel. Now that you know what that little panel is doing, you know what to look for. Frequently asked questions Can I put anything in the gusset pocket? No. It isn't a real pocket, just a gusset with one edge left unstitched during sewing. There's no lining to hold anything, so nothing is meant to go inside it. Is a cotton gusset enough, or do I need all-cotton undies? A cotton gusset puts a breathable layer where it matters most. Doctors note that a cotton panel isn't identical to an all-cotton pair, so if breathability is a priority for you, look for a natural-fibre gusset like our organic cotton one, and choose breathable outer fabrics too. Will a reusable cloth pad stay put in a floating gusset? Yes, and this is where it shines. A cloth pad's poppers snap around the gusset and the open sides hold it steady, which solves the sliding problem cloth pads are known for. Can I still use a floating gusset without a pad? Absolutely. On a normal day it's just comfortable undies. The floating design only comes into play when you add a pad, so you can wear PadStay any day and pop a pad in when you need one. Do your period undies have a floating gusset too? Our leakproof styles use a floating gusset so you can add a pad on heavier days, while our built-in Period Boxer Briefs absorb on their own. You can see both in the period and leakproof range. Is organic cotton actually worth it in a gusset? If your skin is sensitive, it can be. Organic cotton is grown without harsh pesticides and processed with fewer chemical residues, so there's less sitting against your skin all day. Look for GOTS certification when you're comparing.

Underwear riding up isn't about your body, it's the cut. Here's why it happens, why sizing up makes it worse, and the fix that finally stays put.

You know the feeling. You're out, you're having a nice time, and then it starts: the slow crawl of your undies riding up, the thigh rub that turns into a proper sting by lunchtime, or that little panic when you catch a panty line in a shop window. So you do the discreet tug-and-shuffle and hope nobody noticed. If any of that sounds familiar, we promise it's not you. It's almost always the wrong length. Here's the thing most people never get told: no two bodies are the same. Two women can wear the exact same dress size and have completely different waist, hip and thigh measurements. That's exactly why we make our undies in three leg lengths instead of one, so you can pick the amount of coverage that actually works for your body, not settle for whatever the packet gave you. So let's clear it up properly. Boylegs, boxer briefs and biker shorts, what's the real difference, and which one is right for you? The short version is that it all comes down to how much thigh coverage you want. Here's the long version. Quick comparison Length Style Best for What it fixes 3" Boylegs Cheeky, barely-there coverage Under leggings, shorts, fitted skirts No VPL, no wedgies 5" Boxer Briefs Our most-loved everyday length Everyday wear, lounging, sleeping No chafing 8" Biker Shorts Max coverage, tapered leg Fuller thighs, dresses, long days on your feet No ride-up, no chafing Boxers or briefs: what's the real difference? Let's start with the basics, because this trips a lot of people up. Regular briefs stop right at the leg. Nothing runs down your thigh, so they're light, but there's also nothing between your thighs to stop the rub. That's fine until it's warm, or you're walking a lot, or you've got a dress on and your thighs are saying hello to each other with every step. Boxer-style undies fix that. A bit of leg gives your thighs something to glide against instead of each other, so the chafing just stops. That's the whole idea behind our range: instead of the old brief cut, we build everything around leg length, 3", 5" and 8". Once you're choosing by length, the only real question left is how much coverage you actually want. So let's go through them. 3" Boylegs: light, invisible, no VPL These are our barely-there option, and the shortest cut we make. Light, low-bulk, and cut to vanish under leggings, shorts, jeans or a fitted skirt. No visible panty lines, no wedgies, nothing showing through. If you're petite, love a shorter hemline, or you just want to forget you've got undies on at all, these are the ones you'll reach for. They're the go-to for fitted outfits and warmer days, when you want the least amount of fabric without giving up on comfort. And a fair warning: people get a little attached to how these look. Real things customers have actually told us include "I had to stop myself from saying 'feel my bum!'" and "I swear my bum felt 30 years younger." You've been warned. One honest note: because the 3" is our shortest leg, it sits higher on the thigh. If you've got fuller thighs, or ride-up is your main worry, the 5" or 8" will stay put better. But if minimal coverage and a barely-there feel is what you're after, nothing beats the boyleg. Shop 3" Boylegs 5" Boxer Briefs: our most-loved all-rounder If you're not sure where to start, start here. The 5" is the happy middle: enough leg to stop your thighs rubbing, but not so much that it feels like you're wearing shorts under your clothes. It's our most popular length by a mile, and honestly it just works. Under jeans, under work pants, under a dress, in bed, on the couch, at the gym, it does the lot. It's the one most people order first and then come back for in three more prints. Enough coverage to keep chafing away all day, light enough that you forget it's there. If you want one length that handles ninety percent of your week, this is it. Shop 5" Boxer Briefs 8" Biker Shorts: no ride-up, no chafing This is max coverage and max stay-put. The longer leg tapers and sits lower on the thigh, which is exactly why these are loved by curvier ladies, taller ladies, and anyone with fuller thighs. If ride-up or all-day chafing is your biggest gripe, this is the one that finally sorts it. They're brilliant under a flowy dress or a longer skirt, on your feet all day at work, or just worn on their own for lounging around the house. And if you've been reaching for gym bike shorts under your dresses to stop the chafe, you already know the problem: they're thick, hot and bulky, like wearing an extra sweaty layer. Ours aren't. Same light, breathable fabric as the rest of the range, thin enough to disappear under a dress, but with all the coverage you need. Shop 8" Biker Shorts Seamless by design: why the hem matters as much as the length Length is only half the story. The edges matter just as much, and this is where a lot of undies quietly fail. A normal sewn hem leaves a raised ridge that digs into your skin, rolls down as you move, and prints a line straight through your leggings. Not ideal. Every Pure Snug waistband and hem is hot-pressed instead of stitched. That means the edge is bonded flat, with no bulky seam sitting on your skin and nothing to show through your clothes. It's why our hems don't roll or curl over time the way stitched elastic does, and it's a big part of why nothing digs in. Someone asked us recently, "a waistband that doesn't dig in, sure, but does it roll?" Nope. No dig-ins, no roll-ups. The finish moves with you instead of fighting you, wash after wash. Which length stops ride-up best? Ride-up is a mix of fabric, fit and construction, but length does most of the heavy lifting. If it's your main worry, go longer. The 8" biker shorts are your best bet: the extra length tapers and stays snug around the leg, instead of sitting at a point where fabric can bunch up and climb. The 5" boxer briefs are the next best for the same reason. The 3" boyleg, being the shortest, is the most likely to shift, so it's the one to skip if ride-up bothers you more than panty lines do. The fabric: TENCEL™ Micro Modal Every style, boyleg through to biker, is made from the same TENCEL™ Micro Modal. It's a plant-based fibre spun from sustainably sourced beechwood, sometimes called "vegan silk" for how soft it feels, and it's honestly the thing customers rave about most. Here's why it matters: Cool in the heat. "Won't these be hot in summer?" is easily the question we get most. They do look cosy, don't they? But they're much lighter than they look. The fibre producer rates Micro Modal as more breathable than cotton, so it doesn't trap heat against your skin. Dries faster than bamboo. Sweat moves away quicker, so there's no swampy feeling on hot, humid days. Antibacterial gusset. A soft viscose-lined layer right where it counts, for that extra bit of freshness. Stays soft. It doesn't stiffen or pill the way cotton blends tend to after a few dozen washes. Put that fabric together with the hot-pressed edges and the anti-chafe part isn't just a line on a label. It's a genuinely soft, breathable layer with no scratchy seams to bother skin that's already prone to rubbing. That's the whole point of Pure Snug in one sentence. How to choose: three quick scenarios Still deciding? Here's the shortcut: Wearing a dress or skirt: go 5" boxer briefs or 8" biker shorts, for the most secure, no-ride-up fit under fabric that swishes around as you move. Petite, or you just want zero panty lines: the 3" boylegs, light, smooth and invisible under fitted clothes. Fuller thighs, on your feet all day, or heading to the gym: the 8" biker shorts, the tapered leg is built to stay exactly where you put it. Quick sizing tip: our sizes run a little big, so if you're between sizes, size down for your first pair. You'll get that snugger, stay-put fit that keeps ride-up away. Loads of customers tell us the same thing afterwards: "they fit, but next time I'll size down." And if it's still not quite right, our Love at First Snug Guarantee has you sorted, no return needed. Frequently asked questions Are boxer briefs good for women? Yes! Our 5" boxer briefs are cut for a woman's hips and thighs, with a bit of leg that stops chafing whether you're at work, travelling or at the gym. They're designed from scratch for us, not just men's undies made smaller. What's the difference between boylegs and boxer briefs? Boylegs (3") are a shorter, lighter cut designed to get rid of visible panty lines with minimal coverage. Boxer briefs (5") add more leg for proper anti-chafe protection, while still feeling like everyday undies rather than shorts. Which length is best for stopping ride-up? The 8" biker shorts. The extra length creates a naturally tapered hem that stays snug around the leg rather than sitting where fabric can bunch. It's helped along by our hot-pressed waistband and hems too, which have no raised seam to dig in or roll. Won't they be hot in summer? Totally fair, that's what most people think at first. They do look cosy, but they're much lighter than they look. Made from breathable TENCEL™ Micro Modal (more breathable than cotton, dries faster than bamboo), so they're built to keep you cool on hot, humid days. If it's an Australian company, why are the lengths in inches, not centimetres? Fair question. For underwear, leg lengths are more universally described in inches (3", 5", 8"), especially as we also sell to the US and UK. It just makes styles easier to compare. Our size chart includes both inches and cm. Where are Pure Snug undies made? Good question. We actually spent months looking into making them here, but the specialised hot-press machinery we use isn't feasible to run in Australia at a fair price yet. They're made in China with OEKO-TEX certified fabrics, while our support, warehousing and shipping all stay right here in Australia. What are they made from? TENCEL™ Micro Modal, a soft, plant-based fibre spun from sustainably sourced beechwood. It's breathable, quick-drying and gentle on skin, with an antibacterial viscose-lined gusset. We've also got a cotton range with an organic cotton gusset. How do I wash them? Cold wash and air-dry is the golden rule. TENCEL™ Modal is beautifully soft but a little delicate, and high dryer heat can loosen the hot-pressed hem over time. If you can't air-dry, a low tumble setting is your safest bet. Can I wear them for swimming? No. They're made for everyday comfort, not for water, chlorine and sun. Swimwear uses a completely different, more durable fabric. What if my first pair doesn't work out? Pure Snug offers the Love at First Snug Guarantee: try a pair, and if it doesn't live up to expectations, you'll get a refund on your first pair. No return needed.
