If you've ever bought a pair of "leakproof" undies expecting them to work like a pad, then found out the hard way that they don't, you're not the only one. It's one of the most confusing bits of shopping for period gear, because most brands use the words to mean slightly different things. Here's the short answer. Period undies absorb. They have an absorbent panel built in, so they catch flow on their own. Leakproof undies stop leaks getting through. They have a waterproof barrier, but they're a barrier rather than a sponge, so they're designed to be worn with a pad or as backup. And pad-friendly undies simply hold a pad in place. Below is how each one works, which one suits which day, and how to mix them so you're covered without the bulk. Why most brands use "leakproof" and "period underwear" as the same thing Most period brands sell one type of product and call it both names. Their "leakproof underwear" is period underwear: an absorbent layer on top of a waterproof one, sold by how much it holds. So when you search for leakproof undies, that's usually what you're shown. We built our range differently. Instead of one pair that tries to do everything, we make undies with different jobs, plus reusable pads you can add when you need more. That means you choose how much absorbency you want and where it comes from, rather than committing to a thick pair on a day you barely need it. It also means the word "leakproof" means something specific here. On a Pure Snug product it tells you there's a waterproof core. It doesn't tell you the pair will absorb a heavy day on its own, so it's worth reading the next section before you buy. The three kinds of leak protection we make 1. Period undies: they absorb on their own Our Period Boxer Briefs (4″) have a full absorbency panel running from front to back, built into the gusset. You wear them like normal undies, with nothing extra. They're made for lighter days, like the tail end of your period or the sneaky little leaks you don't want to plan around. Because the gusset is attached, they aren't designed to hold a pad as well. If you need more than they give you, that's when the next type comes in. 2. Leakproof undies: a barrier, made to pair with a pad Our Leakproof Boxer Briefs 2.0 (4″) and Leakproof Biker Briefs (8″) have a full leakproof core that runs from the front waistband to the back and down through the leg panels, with an organic cotton top against your skin. On top of that sits a floating gusset that holds a pad with wings. So the barrier stops anything getting through to your clothes, and the pad does the absorbing. On their own they're good for spotting, or as backup under a cup or tampon. For anything more, add a pad. One honest note: because of the extra core, these feel a little firmer than our everyday undies. Most people don't mind on the days they need them, but it's worth knowing so it doesn't surprise you. Shop Period & Leakproof 3. Pad-friendly undies: they just hold the pad still Our PadStay range has a floating organic cotton gusset but no leakproof core. It's for anyone who already uses liners or pads and is sick of them shifting halfway through the day. The floating gusset gives winged pads something to wrap around, and it takes liners well too. Customers who use them this way tend to say the same thing. Cathy wrote that the floating gusset is great for attaching a pad for extra protection, and Sheryl found that the liners she now needs sit beautifully on both the fixed and floating gusset. How to match your undies to your flow Think of it as two choices: the undies decide how protected you are, and the pad decides how much you can absorb. Our reusable pads come in three levels. Panty Liners cover spotting and everyday freshness. Day Pads suit light to medium flow. Night Pads are for heavy flow and overnight. Your day Undies Add a pad? Spotting, first or last day Period Boxer Briefs No Backup under a cup or tampon Leakproof Boxer or Biker No Light to medium flow Leakproof Boxer or Biker Day Pad Heavy days and overnight Leakproof Boxer or Biker Night Pad Everyday discharge or freshness Any PadStay style Panty Liner None of our undies are designed to handle a heavy day on their own. For those, the leakproof core plus a Night Pad is the combination to reach for. Everyone's flow is different, so it's worth trying a new setup at home or overnight first, until you know how it works for you. Leaks that aren't periods Leakproof undies aren't only for your period. Plenty of people get the odd bladder leak when they laugh, sneeze, jump or go for a run, and a leakproof pair with a liner or Day Pad makes those moments a lot less stressful. The same setup works for discharge, or just for days when you want to feel extra covered. They're made for light leaks, not for ongoing incontinence. If leaks are new for you, happening more often or getting worse, it's worth a chat with your GP or a pelvic floor physio. This is general information, not medical advice. Why leg length matters for leaks This is the part most period undies skip. A lot of period briefs are cut high on the leg, which leaves very little coverage at the back and around the legs, and that's exactly where leaks tend to escape when you're sitting for a long time or lying down. Our period and leakproof styles come in a 4″ boxer and an 8″ biker. The longer leg keeps more coverage where you need it, with the leakproof panels running down into the leg. Your thighs don't rub together either, which matters more than you'd think on a hot day. They come in sizes XS to 5XL, so you don't have to size down your comfort to find a pair that fits. Lynne, who wears the 8″ biker, put it simply: she also got the winged pads, found them very comfortable, and said there's no rubbing like liners from the supermarket. What they're made of The body of every pair is our soft, breathable modal, the same fabric as our everyday undies. The leakproof core has an organic cotton top layer against your skin, and the floating gussets are organic cotton too. The range is PFAS-free. Our reusable pads have three layers: 100% organic cotton on top, an absorbent terry core in the middle, and a leakproof layer on the bottom. The pad fabric is OEKO-TEX certified. Looking after them Give them a rinse in cold water first until it runs clear, then cold machine wash in a laundry bag. Air dry recommended. If air drying isn't practical, tumble dry on low heat. Don't use bleach, and skip the fabric softener, since it can coat the fabric. Our full guide to washing period undies goes through it step by step. Frequently asked questions What's the difference between leakproof and period underwear? Period underwear has an absorbent panel built in, so it catches flow on its own. Leakproof underwear has a waterproof barrier that stops leaks reaching your clothes, but it doesn't absorb much, so it's designed to be worn with a pad or as backup. Can you wear leakproof undies without a pad? Yes, for spotting or as backup under a cup or tampon. For anything more than that, add a pad. The leakproof core stops leaks getting through, and the pad does the absorbing. Are leakproof undies good for bladder leaks? For light bladder leaks, like the odd leak when you laugh or sneeze, a leakproof pair with a liner or Day Pad works well. They aren't designed for ongoing incontinence. If leaks are new or getting worse, talk to your GP or a pelvic floor physio. Can I wear period undies overnight? None of our undies are designed for heavy flow or overnight on their own. For nights and heavy days, wear Leakproof Boxer Briefs or Biker Briefs with a Night Pad in the floating gusset. Do leakproof undies feel different to normal undies? A little. The leakproof core makes them slightly firmer than our everyday styles. They're still soft modal on the outside with organic cotton against your skin. What sizes do they come in? Our women's period and leakproof range comes in XS to 5XL, in a 4″ boxer and an 8″ high-waisted biker. Find your leak-free setup  

Underwear is the last thing you think about before a workout, and the first thing you notice when it's wrong. The pair that rides up mid-squat, the lace that chafes on a run, the cotton that's soaked through by your second set. What you wear underneath makes more difference to a workout than most people give it credit for. The honest answer to "what's the best underwear for working out" is: it depends what you're doing. Running, lifting, yoga and a sweaty HIIT class all ask for something slightly different. Here's a no-nonsense guide, sorted by workout, plus the things that matter no matter what you're doing. What actually matters in workout underwear Before the specifics, four things separate underwear you forget you're wearing from underwear you fight with the whole session. It has to breathe and handle moisture. This is the big one. Cotton feels soft but it absorbs sweat and holds onto it, so it stays damp against your skin the whole workout and long after. A breathable fabric that releases moisture faster keeps you cooler and drier. That's why we make ours from modal, which is more breathable than cotton and doesn't cling once you start sweating. It has to stay put. Repetitive movement is where cheap underwear fails. Squats, lunges and running all work a short leg or a thin waistband loose until you're adjusting between reps. A leg that grips without digging, and a waistband that doesn't roll, is the difference between forgetting about it and fixing it every five minutes. It shouldn't chafe. Seams in the wrong place, lace edges, or thighs rubbing skin-on-skin all turn into raw patches over a long session. Flat, bonded edges and a bit of leg coverage solve most of it. It shouldn't show. Under thin leggings, a lacy or seamed pair prints straight through. Flat, hot-pressed edges sit invisible where a stitched seam would show a line. The best underwear by workout Running Running is repetitive, sweaty, and long, which is the hardest combination for underwear. You want something breathable that won't hold moisture, with a leg long enough to stop your thighs rubbing over the miles. A boxer brief with a bit of leg is the sweet spot for most runners: enough coverage to stop chafe, light enough that you don't feel it. If your thighs touch or you're running distance, size up the leg to a longer biker length. Our pick: the 5″ boxer brief for most runners, or size up to the 8″ biker if your thighs touch or you run distance. Shop the 5″ boxer – $27 Lifting and strength training Lifting isn't about sweat so much as position: deep squats, hip hinges, lunges. That's exactly where a short leg climbs and a thong migrates. Go for more coverage, not less. A boxer brief stays anchored through the full range of motion, so you're thinking about your form and not your underwear. Our pick: the 5″ boxer brief, anchored through every squat, hinge and lunge. Shop the 5″ boxer – $27 HIIT, bootcamp and circuits Fast, explosive, sweaty. This is the workout that exposes anything that rides up or holds moisture, because you're changing direction constantly and sweating hard. A longer, breathable pair that grips the leg is your friend here. If one workout is going to make you notice your underwear, it's this one, so pick your most stay-put pair. Our pick: the 8″ biker, the most stay-put coverage we make, for fast, sweaty, change-direction workouts. Shop the 8″ biker – $27 Yoga and Pilates Different problem entirely. Here it's not sweat or movement, it's thin leggings and revealing positions. The complaint we hear most is fabric bunching at the front in a forward fold. A flatter, wider cut sits smooth instead of gathering into the middle, so a boyleg or boxer works better than a narrow bikini. Thin and seamless matters more than coverage. Our pick: the 3″ boyleg, thin and flat so it won't bunch at the front or show under thin leggings. Shop the 3″ boyleg – $24 Spin and cycling On the bike you're sitting on a seam for 45 minutes, so the last thing you want is more seams underneath. A smooth, flat, breathable pair with no bulky edges sits comfortably against the saddle. Skip anything with thick seams or lace at the leg. Our pick: the 3″ boyleg for the least bulk against the saddle, or the 5″ boxer if you want more leg coverage. Shop the 3″ boyleg – $24 Should you even wear underwear to work out? Fair question, and you'll hear both answers. A lot of leggings and bike shorts come with a built-in gusset and are designed to be worn on their own, and plenty of people do exactly that, especially for a short, sweaty session where an extra layer feels like too much. There's nothing wrong with going without if that's comfortable for you. That said, many people prefer a thin layer of breathable underwear for hygiene and for a barrier between skin and shared equipment or thin leggings. If you do wear a pair, the rules above still apply: breathable, stays put, no chafe. The worst option is a thick, sweat-holding pair that traps everything against your skin. The one habit that matters most: change out afterwards Whatever you wear, the single best thing you can do for comfort and freshness is get out of sweaty underwear and leggings soon after you finish, rather than running errands in them for the rest of the afternoon. Sitting in damp fabric is what leads to irritation and that not-so-fresh feeling. A breathable fabric that dries faster helps, but nothing beats a quick change. This is general information, not medical advice, so if something doesn't feel right, check with your doctor. What to look for, and what to skip Look for: a breathable fabric like modal that releases moisture rather than holding it; flat, bonded or hot-pressed edges that won't dig, roll or show; enough leg to stop your thighs rubbing; and a smooth, tagless build with no scratchy seams. Skip: all-cotton (holds sweat), lace or heavily seamed pairs (chafe and print through leggings), and anything with a thin elastic leg that rolls up the moment you move. Which one for you? Each workout above has its pick, but if you want the short version: the 5″ boxer is the do-it-all default, the 8″ biker is for high movement or fuller thighs, and the 3″ boyleg is your yoga and under-leggings option. All come in breathable black modal, XS to 5XL. If you want the deeper dive on going invisible under thin leggings specifically, we cover that in what to wear under leggings, and if chafing is your main issue, how to stop chub rub goes further on that. Frequently asked questions What is the best underwear for running? A breathable pair with a bit of leg, so it won't hold sweat and won't let your thighs rub over distance. A boxer brief suits most runners; go longer if your thighs touch or you run distance. Should you wear underwear when working out? It's up to you. Many leggings and bike shorts have a built-in gusset and can be worn alone. If you prefer a thin layer for hygiene or a barrier under thin leggings, choose a breathable pair that stays put and doesn't chafe. Is cotton underwear bad for the gym? Cotton isn't dangerous, but it absorbs sweat and holds it against your skin, so it stays damp through a workout. A breathable fabric that releases moisture faster, like modal, feels cooler and dries quicker. What underwear stops chafing during exercise? A pair with enough leg to keep your thighs from rubbing, plus flat, bonded edges rather than seams or lace. A longer boxer or biker length is the most reliable for high-movement workouts. What's the best underwear for yoga? Something thin, flat and smooth that won't bunch at the front during forward folds or print through thin leggings. A boyleg or boxer cut works better than a narrow bikini. How do I stop underwear riding up at the gym? Choose a longer leg with a flat, hot-pressed hem that grips your thigh instead of a thin elastic edge that rolls. The longer the leg, the more reliably it stays put through squats, lunges and running. Should I change out of my underwear after a workout? Yes, when you can. Getting out of sweaty underwear and leggings soon after you finish helps you stay fresh and comfortable, rather than sitting in damp fabric all afternoon. Shop workout-ready underwear  

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
