For years I hiked in whatever underwear happened to be clean, and for years I paid for it: waistbands that rolled down under a hip belt, seams that turned to sandpaper somewhere around mile eight. Switching to a pair actually built for the trail was embarrassingly overdue, and I haven’t gone back. What good hiking underwear fixes is simple — it moves sweat off your skin, sits flat where a pack strap lands, doesn’t need to be swapped out every day of a long trip, and still looks like something you’d willingly wear.
Plenty of pairs promise all three. Over the past six months, my team and I put 14 pairs through day hikes, a couple of overnighters, and plenty of trail miles, and the gaps showed up hours in, not minutes. Fabric matters less than where the seams sit, and sizing swings so much between brands that a medium in one is a small in another. We kept notes on every pair through repeated washes, and the ones worth your money are below.
Best for Multi-Day Trips
ExOfficio Give-N-Go 2.0 Brief
Key Features
- Cut: Full cut brief
- Collection: Give-N-Go 2.0
- Stated qualities: Breathable, durable, easy care
- Price: Premium
Most of the underwear in this guide is workout gear that happens to travel well. The Give-N-Go 2.0 is the other way around: a piece of travel kit comfortable enough to wear on an ordinary Tuesday. That is why it is our top pick. When a trip means washing in a basin at night and pulling the same pair on at dawn, this is the one we want in the bag.
What makes it work is how little water the fabric holds. A hand wash with a dab of shampoo rinses out clean and hangs dry by morning, and the full cut sits higher at the waist than a standard brief, so it stays put under a hip belt instead of rolling down. The leg openings lie flat rather than pinching, which matters more than any fabric claim once you are six hours into a climb.
The surprise is how little it changes with use. Synthetics often relax after a few hard wringings and stop sitting where they started the trip; this one comes back to the same shape, so the pair you pull on at the end of a week fits like the one you started with. Nothing about it is fussy, and nothing about it needs a washing machine.
Pros
- Hangs dry overnight after a sink wash
- Full cut stays flat under a hip belt
- Keeps its shape through repeated hand washing
Cons
- Highest price per pair in this guide
It’s the pair we trust when the wash happens in a sink: quick to dry, flat-seated under a hip belt, and it keeps its shape. Worth the premium if you hike multi-day.
Best for Wash-And-Wear Travel
Balanced Tech Seamless Hipster
Key Features
- Cut: Bikini
- Construction: Seamless
- Stated performance: Moisture wicking
- Price: Midrange
Two weeks of hiking out of a carry-on is a strange test for underwear, and this is the pack that made it work. Wash a pair before dinner, wring it, hang it on a towel rail, and it is ready when you are. The fabric is thin and smooth and lets go of water quickly, which is exactly the property you want when the washing machine is your own hands.
That is why it earns a place as the value route to fast drying. It wicks well enough that a hard climb does not leave you clammy, the bikini cut sits low enough to disappear under hiking trousers, and it stayed where we put it through a long descent rather than creeping with every step.
One thing to know before ordering: the sizing runs small. Take the size up from your usual — the stretch is forgiving, but the leg openings are cut close, and a pair that is a size tight will bunch by mid-afternoon. That is the opposite of what you bought it for.
Pros
- Dries fast after a hand wash
- Wicks sweat on hard climbs
- Low bikini cut disappears under trousers
Cons
- Seams can come apart in the wash
Our pick when the laundry happens in a hostel sink: quick-drying, genuinely wicking, and comfortable enough for a full day on the move without shifting.
Best for Thigh Chafe
Bamboo Cool High-Waisted Boyshorts
Key Features
- Cut: High-waisted boyshort
- Coverage: Full coverage
- Pack count: 5 pack
- Price: Premium
If your thighs touch, you already know that no amount of moisture wicking saves a hike once the rubbing starts. A boyshort is the underwear answer to that, and this pair covers more skin than anything else here: high waist, wide band, and legs cut low enough to sit over the rub line instead of stopping short of it.
The fabric is the other half of the story. It is a bamboo blend, thin and cool, and the breathability is what makes a full-coverage cut wearable in summer heat — we never felt the greenhouse effect that usually comes with extra fabric. The wide waistband sits flat under a hip belt and does not dig in, which is more than we can say for narrower bands on a long carry.
There is a cost to the coverage, and it shows up at wash time: more fabric means more water, so a boyshort takes a harder wring and longer on the line than a brief. We still pack it for hot trips where thigh rub is the bigger problem, because chafe ruins a day faster than a damp pair does. The sizing runs close, so order up if you are between.
Pros
- Full coverage over the rub line
- Wide waistband stays flat under a pack belt
- Breathable and cool in heat
Cons
- Legs can roll up while walking
Our pick when the problem is thigh rub rather than sweat: full coverage, a wide waistband that stays flat, and fabric that stays cool under a pack.
Best for Budget Day Hikes
Fruit of the Loom Breathable Briefs
Key Features
- Cut: Brief
- Sizing: Available in plus size
- Stated performance: Moisture wicking
- Price: Budget
Not every hike needs a purpose-built pair, and this is the pack that proves it. It is the cheapest way here to fix the sweaty-underwear problem on a day hike, and it does the two things that matter most at that level: it breathes, and it stays where you put it.
Breathability is the strength. The fabric is light and airy enough that a summer climb does not turn into a sauna, and the brief cut gives full coverage without showing a line under trousers. It feels closer to everyday underwear than to technical kit, which is precisely why it is easy to recommend to someone who gets out a few times a month rather than every weekend.
Where it differs from the pairs at the top of this guide is in what it is built to survive. This is underwear for a drawer at home rather than a week of basin washing, and we treat it that way: it goes in the case for a weekend, not for a fortnight with no laundry. For that job, nothing here beats it on cost.
Pros
- Breathes well on hot climbs
- Stays in place without riding up
- Cheapest way to stock a trip drawer
Cons
- Colors can differ from the listing photos
The pack we point people to when they are not ready to spend on hiking-specific underwear: breathable, stays put, and cheap enough to fill a trip’s drawer.
Best for Hot Weather
Bamboo Cool Mid-Waist Briefs
Key Features
- Cut: Mid-waist brief
- Pack count: 5 pack
- Stated performance: Moisture wicking
- Price: Premium
Heat is where most underwear gives up. Cotton stays damp, tight elastics turn into a rash, and by mid-afternoon the whole thing is a distraction you cannot fix on the trail. This pair handles it better than anything else in the guide: thin fabric, plenty of airflow, and a surface that feels dry again shortly after you have been sweating in it.
That is why it is our pick for hot trips. The bamboo blend is soft and cool against the skin, and it wicks the way the label promises — a sweaty climb in humid air leaves the fabric damp for a few minutes rather than for the rest of the day. It is thin enough to dry quickly on a line, too, which is why it goes in the bag for summer even though it is not sold as hiking kit.
The fit needs a note. It is cut close through the waist and the sizing runs small, so take the next size up, especially if you are between two. Get that right and the mid rise sits under a hip belt without bunching beneath it. The colours are the nicest in this guide, which is a small thing until you are packing.
Pros
- Wicks sweat and stays cool
- Very breathable bamboo blend
- Soft, thin and light on the skin
Cons
- Waistband can slide down during the day
Our hot-weather pick: a thin, cool bamboo blend that moves sweat away fast and stays comfortable through a long, humid afternoon.
Best for Thong Wearers
GRANKEE High-Waisted Thong
Key Features
- Cut: High-waisted thong
- Style: Seamless, no-show
- Pack count: 6 pack
- Price: Midrange
A thong is either the obvious answer or an immediate no, and there is not much middle ground. If it is the first, this is the pair worth trying: high-waisted, stretchy, and cut so the fabric sits where you put it rather than migrating on the first climb.
The high waist does real work here. It holds the band above the waistband of hiking trousers rather than under it, and it stays there through a day of sitting, stepping and scrambling. The stretch is generous in every direction, which is why it moves with you instead of digging in at the hip.
One detail matters for multi-day trips: the gusset is cotton. That is comfortable against skin, but cotton holds water, so this is the slowest-drying pair here in the part of the garment that matters most. On an overnight trip, give it more line time than a synthetic brief and hang it where the air moves.
Where it earns its place is as a change of shape rather than a change of standard: the same comfort and stretch as the workout pairs, in a cut that suits hikers who hate the feel of fabric creeping. Six in a pack also means you rotate rather than wash nightly, which is its own kind of convenience on a short trip.
Pros
- High waist stays above trouser waistbands
- Generous stretch without digging in
- Six-pair pack spreads the cost
Cons
- Not truly seamless under thin leggings
- Sizing is inconsistent between buyers
A genuinely comfortable high-waisted thong for hikers who would rather not have fabric where it bunches, in a pack that keeps the cost per pair low.
How We Tested the Best Hiking Underwear for Women
We started by rounding up every pair marketed for hiking or long, sweaty days — merino, synthetic blends, and seamless knits — then cut anything that only came in a narrow size range, anything with flatlock seams placed right where a hip belt sits, and anything priced like technical gear without the construction to justify it. That left 14 pairs, which we wore over six months.
Testing happened where underwear actually gets tested: on day hikes with a loaded pack, on a hot, exposed climb with no shade, and across two overnight backpacking trips where laundry wasn’t an option. On those trips we wore pairs a second day, rinsed them in a sink, and hung them to dry overnight to see whether they came back wearable by morning.
Under a hip belt we noted whether each waistband stayed flat, rolled down, or dug in, and whether the seamless styles stayed put or crept up. We measured every pair flat against its own brand’s size chart and had testers of different body types compare notes, since a medium is not a medium across the board. Comfort got judged at mile ten rather than minute ten — the pairs that worked were the ones we stopped thinking about.
Every pair went through the wash after each wear, and we checked for pilling, thinning fabric, stretched elastic, and holes along the gusset as the months went on. We also watched how shape and color held up after repeated washing, since a pair that looks shot after one season isn’t a bargain. Value came down to cost per wear rather than price per pair.
How to Choose Hiking Underwear for Women
The decision that matters most is how fast a pair gives up water — most of the others follow from it.
Drying speed is the whole game
On a multi-day trip you wash a pair in a basin and want it wearable by morning, so how quickly the fabric releases water beats softness, colour and everything else. Cotton is the wrong answer here: it holds moisture against the skin and stays damp for hours. Thin synthetics and bamboo-viscose blends shed water quickly, and the thinner the fabric, the faster it goes.
You can test a pair before you commit. Wet a corner, wring it out and hang it. If it is still noticeably damp an hour later, it belongs in a day-hike drawer rather than a trip bag.
Chafe comes from seams and edges
Rubbing on a long climb usually starts at a leg opening, a waistband, or a seam that sits proud of the fabric — not in the middle of the panel. Look for flat seams, leg openings cut close without biting, and a waistband with a smooth inner edge.
A boyshort puts fabric between the thighs, which helps if that is where you rub. But it only helps while the legs stay down; if they roll, the extra coverage makes things worse. Check that the leg hem sits flat before you commit to a full-coverage cut.
Match the cut to what you’re wearing
A brief or hipster disappears under trousers and dries fastest because there is less fabric to wet. A boyshort earns its place under a skirt or loose shorts. A thong removes bunching entirely for hikers whose briefs migrate, which is the whole argument for it.
Rise matters as much as shape. A high waist sits above a hip belt and stays there when a pack pulls; a mid rise sits lower and can slide under a tight strap. Try the combination on with your pack loaded before a long trip.
Sizing is where these go wrong
Several pairs in this guide run small, and a size that is tight at the leg opening will creep and bunch by mid-afternoon — exactly the problem you are trying to solve. Measure your hips and waist and use the brand’s chart in inches rather than reaching for your usual S, M or L.
If you are between sizes and heading out for several days, go up. The stretch takes up the slack, and a slightly loose pair is far easier to live with on the move than a tight one.
Two or three pairs is enough
You do not need seven. Two pairs let you wear one and wash one; three gives you a spare for a wet night. Wash in the sink or a dry bag with a dab of soap, rinse thoroughly, wring the pair inside a towel, and hang it where air moves past both sides.
Humid weather slows everything down, so on a rainy trip make the fastest-drying pair the one you keep in rotation and let the others wait.
Frequently Asked Questions
Is it worth buying special underwear for hiking?
For day hikes, not really. A breathable multipack covers it, and our budget pick exists for exactly that. The calculation changes on trips where you wash in a basin: drying speed and how a pair survives repeated wringing become the difference between a comfortable week and a damp one.
Start cheap, and spend more only once drying has actually become your problem.
How do I get a pair dry overnight in a tent?
Wring the water out inside a dry towel — roll the pair up in it and press hard on the roll — then hang it rather than laying it flat. A guy line, a pack haul loop or the loop inside a tent door all work.
Moving air is what dries fabric, so a sealed tent on a humid night is the worst case. Leave a vent open and hang the pair where the draught passes.
Will quick-dry underwear wear out faster?
It can, and the weak points are the seams and the waistband elastic rather than the fabric itself. Thin synthetics handle wringing well but do not like heat: a hot wash or a tumble dryer breaks down stretch and frays seams within a few trips.
Wash cool, skip the dryer and line dry — the care that makes these last is the same care that keeps them drying fast.
Final Verdict
Our default recommendation for a hiking trip is the ExOfficio Give-N-Go 2.0 Full Cut Brief. It dries overnight, sits flat under a hip belt, and keeps its shape through exactly the kind of washing a multi-day route demands. For most hikers that combination settles it.
If you want a whole pack for less, the Balanced Tech hipster is the value route to the same fast drying. And if thigh rub is your problem rather than sweat, the Bamboo Cool boyshorts cover what a brief cannot.
