Moisture Wicking Underwear: The Unfiltered Guide to Staying Dry (US 2026)

Moisture Wicking Underwear: What It Actually Does (and What It Doesn’t)

Moisture wicking underwear is not a magic trick. It is textile engineering with a narrow, useful job: move liquid sweat away from your skin faster than the fabric can soak it up. That is the whole promise. Everything else — the cooling claims, the “dry all day” badges, the vaguely scientific names involving the word “air” — is downstream of that one mechanical function.

The problem is that most shoppers buy wicking underwear the way they buy running shoes: by color, price, and whichever influencer looked good in them. Then they wonder why a $6 multipack from a big-box retailer feels like wearing a damp washcloth by 10 a.m. The fabric was never built for the job. It was built to be cheap, stretchy, and acceptable under a pair of jeans for a two-hour dinner.

Here is the short version before the long one: moisture wicking underwear works when the fabric has a hydrophobic interior (pulls sweat off skin), a hydrophilic exterior (spreads it out to evaporate), and enough airflow to let evaporation happen. Miss any of those three, and you have paid a premium for a label.

The physics of a dry crotch, minus the marketing

Sweat does not “wick” because a brand says so. It moves through capillary action — tiny channels between fibers pull liquid along a pressure gradient. Flat, dense cotton has a tight structure; it absorbs water and holds it against your skin. Polyester and nylon filaments can be engineered into open, porous knits that transport moisture to the surface and release it. Merino wool does something different: the fiber’s scaly surface and internal structure absorb vapor and release it slowly, which is why it feels dry even when it is technically holding moisture.

The practical consequence is that two pairs both labeled “moisture wicking” can behave nothing alike. A dense, cheap polyester brief with a thick waistband may wick for twenty minutes and then turn into a sauna. A well-constructed nylon mesh brief with flatlock seams and a thin gusset will keep moving moisture for hours. The label is the start of the conversation, not the end.

Why cotton is the wrong answer for sweat (and when it isn’t)

Cotton is comfortable, breathable in the loosest sense, and genuinely terrible at handling liquid sweat under pressure. It absorbs water readily and releases it slowly. That is fine for a T-shirt on a breezy day. It is not fine for the crotch of someone who runs hot, sits in a humid office, or does a lunchtime workout and then returns to a desk.

But cotton is not the villain of every story. A cotton gusset — the liner panel that touches the vulva — is still the dermatologist-recommended choice for many women because it is breathable and non-irritating when dry. The mistake is buying a 100% cotton main body and expecting it to manage sweat during a spin class. Use cotton where it belongs: as a liner, not as the engine.

The three failure points: gusset, waistband, leg opening

Most wicking failures happen at the edges, not the center. The gusset is where moisture accumulates first; if it is a thick, non-wicking cotton panel sewn into an otherwise technical brief, you have built a dam in the middle of a river. The waistband is where heat and sweat pool against the lower back; a wide, non-breathable elastic band turns that zone into a moist ring. And the leg opening is where chafing begins — if the seam is thick, the fabric is stiff, or the leg hem rolls, the wicking properties of the main body are irrelevant.

When you evaluate a pair, flip it inside out. Run your thumb across the gusset. Bend the waistband. Stretch the leg opening. If any of those three feel heavy, stiff, or non-breathable, the pair will underperform no matter what the hangtag says.

Fabric Face-Off: Polyester, Nylon, Merino, Bamboo, and the Blends That Work

Fabric is the whole ballgame. Fit and seams matter, but they cannot rescue a bad textile. The US market is saturated with claims, so here is a practical hierarchy based on how these materials behave after repeated wear and wash — not how they feel on the hanger.

Synthetic performance fabrics: the real workhorses

Polyester and nylon are the backbone of moisture wicking underwear because they can be engineered at the filament level. Fine-denier polyester can be knit into an open mesh that moves sweat quickly and dries in minutes. Nylon is stronger and smoother; it is often blended with spandex for stretch and recovery. The best synthetics feel slightly cool to the touch and have a visible texture — tiny holes, a mesh pattern, a ribbed channel — that increases surface area for evaporation.

The weakness is odor. Synthetic fabrics can harbor bacteria if they are not washed promptly or if the fabric is too dense to dry fully between wears. Some brands treat the yarn with antimicrobial finishes; those finishes fade with washing, so do not expect a permanent shield. The workaround is simple: buy lighter-weight synthetics for high-sweat activities and wash them after every wear. No exceptions.

Merino wool: the expensive, stink-resistant outlier

Merino wool is the only natural fiber that genuinely competes with synthetics on moisture management, and it wins on odor control. The fiber absorbs moisture vapor inside its structure and releases it gradually, so the fabric feels dry against skin even when it is holding sweat. It also resists odor naturally, which is why long-distance hikers and multi-day travelers pay $30–$40 a pair without flinching.

The trade-offs are real. Merino is less durable than nylon or polyester; high-friction areas can develop holes faster. It also takes longer to dry than a thin synthetic mesh. For running in hot, humid weather, a lightweight synthetic usually outperforms merino on pure dry speed. For travel, cold-weather running, or anyone who prioritizes odor control over rapid drying, merino is the better call.

Bamboo viscose and modal: soft, sustainable, not all equal

Bamboo viscose and modal (often branded as MicroModal) are regenerated cellulose fibers. They are exceptionally soft, drape well, and feel cooler than cotton against skin. Their moisture wicking is decent — better than cotton, not as fast as engineered polyester — and they are a good middle ground for everyday wear, especially for people who find pure synthetics plasticky or irritating.

The catch is durability and drying speed. Bamboo viscose can pill and stretch over time, and it holds moisture longer than a performance mesh. If you are buying bamboo underwear for a sweaty commute or a moderate workout, it will feel pleasant. If you are buying it for a humid 10K, it will feel damp by mile four. Match the fabric to the sweat load.

Cotton’s role: gusset liner, not main body

Cotton’s place in a moisture wicking pair is the gusset. A cotton gusset provides a breathable, non-synthetic surface against sensitive skin, and it is easy to wash at high temperatures. The main body should be a performance blend that moves moisture away from that liner. A pair that is 95% cotton with a token “moisture wicking finish” is not a performance garment; it is a cotton garment with a marketing sticker.

There is one exception worth noting: very loose, lightweight cotton boxers for sleeping or lounging in dry climates. Airflow does the work that the fabric cannot. But for any activity that involves sustained sweat, cotton as the main body is a liability.

Best Moisture Wicking Underwear for Men: Brands That Survive Real Sweat

Men’s wicking underwear is a crowded, loud category. Nearly every athletic brand has a pair, and most of them are fine for a casual gym session. The pairs that earn a recommendation here are the ones that still work after a dozen washes, a few long runs, and a genuinely disgusting humid commute. The US market has a few standouts that separate themselves through construction, not marketing spend.

ExOfficio Give-N-Go 2.0: the travel-tested benchmark

ExOfficio’s Give-N-Go line has been the default recommendation for travelers and outdoor minimalists for years, and the 2.0 version earns that reputation. The fabric is a nylon-elastane blend with a mesh structure that dries remarkably fast — wash it in a sink, wring it out, hang it overnight, and it is ready by morning. The odor resistance is not as strong as merino, but it is better than most untreated synthetics. The fit is supportive without being compressive, and the waistband holds without rolling.

Where it falls short: the fabric can feel slightly slick, and the pouch design is not as anatomically shaped as SAXX or Duluth. For pure travel and everyday performance, it remains the safest recommendation in the US market.

Duluth Trading Armachillo: the cult pick for heat and chafe

Duluth’s Armachillo has a borderline cult following on Reddit’s r/BuyItForLife for one reason: it handles heat and chafe better than almost anything else at its price. The fabric has a cooling, almost mineral hand-feel, and the longer leg options reduce thigh friction for men who deal with chub rub. The pouch is supportive, and the waistband is wide enough to stay put during movement.

The downside is availability and sizing. Duluth’s physical footprint is smaller than a national big-box chain, and the Armachillo line does not always have the full size range in stock. But for hot-weather work, hiking, or anyone who spends the day on their feet in a warm climate, it is a top-tier choice.

SAXX DropTemp and Kinetic: pouch engineering for humid climates

SAXX built its brand on the BallPark Pouch, a internal sling that separates the anatomy and reduces skin-on-skin contact. The DropTemp Cooling Mesh version takes that design and wraps it in a lightweight, highly breathable mesh that is genuinely effective in humid heat. The Kinetic line adds a more compressive fit for high-impact activities.

Is the pouch gimmick? No — it is mechanical separation, which reduces friction and moisture trapping. The trade-off is price. SAXX sits at the premium end of the US market, and the mesh versions are not as durable as ExOfficio’s nylon blend over years of washing. But for humid climates and high-sweat days, the DropTemp is one of the most effective pairs available.

Mack Weldon AirKnitx: the comfort-first premium option

Mack Weldon’s AirKnitx is the pair you buy when you want wicking performance without the plasticky feel of traditional athletic mesh. The fabric is a knit blend that feels soft and slightly substantial, with good stretch and a waistband that does not dig. It is not the fastest-drying pair on this list, but it is one of the most comfortable for all-day wear, which matters if you are not actually running a marathon every day.

The price is the obstacle. AirKnitx sits firmly in the “treat yourself” tier, and the brand’s return policy is stricter than some competitors on worn items. Buy one pair first before committing to a drawer full.

Uniqlo AIRism: the budget disruptor

Uniqlo AIRism is the pair that makes expensive wicking underwear look overpriced. The fabric is a fine-gauge synthetic with a smooth, cool hand-feel and a mesh version that breathes well. It dries quickly, packs down small, and costs a fraction of the premium brands. For everyday wear and moderate workouts, it is genuinely good.

The caveats are fit and durability. AIRism runs slim, and the waistband can roll on some body types. The fabric is thinner than ExOfficio or Duluth, so it will not last as long under heavy use. But as a budget entry point or a travel backup, it is hard to beat.

Smartwool Merino: the odor-control specialist

Smartwool’s merino boxer briefs are the pick for anyone who has ever peeled off a synthetic pair after a long flight and wondered if they should burn it. Merino’s natural odor resistance is the real deal: wear a pair for two days of travel with airing out overnight, and it will not smell like a gym bag. The fabric regulates temperature well across cool mornings and warm afternoons.

It is not the fastest-drying option, and the price per pair is high. But for travel, cold-weather running, or anyone who prioritizes odor control over rapid dry time, Smartwool is a specialist worth paying for.

Best Moisture Wicking Underwear for Women: Fit, Coverage, and the Gusset Reality

Women’s wicking underwear has a different set of constraints. The gusset is a critical health and comfort zone, not just a construction detail. Seams under leggings are a visual problem and a chafe problem. And the range of styles — thong, bikini, brief, boy short — means the same fabric can behave differently depending on how much coverage it provides. The US market has a handful of pairs that get the balance right.

Knix and the leakproof-adjacent category

Knix built its reputation on leakproof period underwear, but the brand’s Essential No-Show Bikini is a genuinely good moisture-management pair even for non-period use. The nylon-Lycra blend is smooth and lightweight, with a cotton gusset for breathability. In Good Housekeeping Institute testing, the pair absorbed more liquid than expected for its thinness, and testers praised the barely-there feel.

The trade-off is the waistband. Some testers found it loose and prone to shifting, which is a problem if you are wearing the pair under leggings or a fitted dress. Try one pair before buying a multipack.

Tommy John Air: no-show performance that stays put

Tommy John’s Air Brief and Air Thong are the pairs to look at if you want wicking performance without visible lines. The fabric is a lightweight nylon-spandex blend that manages moisture and stays flat under clothing. In previous testing, the Air line held up well after washing and stayed in place during movement — which is more than most no-show pairs can claim.

The seams are the weak point. A few loose threads have been reported around the gusset and leg openings, which is annoying at the price point. But for leggings, workout classes, and warm-weather travel, it is one of the most reliable no-show options in the US.

Athleta Sleek Form: lightweight, seam-flat, legging-friendly

Athleta’s Sleek Form bikini is made from a recycled nylon-elastane blend with raw-cut seams that lie flat against the body. The fabric is designed to wick and dry quickly, and the medium-rise cut provides more coverage than a thong without feeling bulky. It is a strong choice for yoga, pilates, and everyday wear under fitted clothing.

The limitation is coverage preference. If you want high-rise or full-coverage underwear, this is not the pair. The medium rise sits below the waistband of many high-rise leggings, which can create a visible transition line.

Bombas Active: the sock brand’s underrated underwear

Bombas is known for socks, but the brand’s Active No-Show Thongs and briefs are a legitimate wicking option. The fabric is lightweight and breathable, with a seamless construction that reduces chafe. The no-show cut works under most workout bottoms, and the brand’s overall quality control is strong.

The sizing runs slightly small, and the thong style is not for everyone. But if you already trust Bombas for socks, the underwear is a low-risk add-on.

Step One Women’s Boxers: chafe reduction for thighs that touch

Step One’s women’s boxer briefs are designed for a specific problem: thigh chafe. The bamboo viscose fabric is soft, moisture-wicking, and has Ultraglyde panels that reduce friction between the legs. For women who wear dresses or skirts in hot weather and deal with inner-thigh rubbing, this is a practical solution that does not require bike shorts.

The boxer cut is not for everyone, and the bamboo fabric dries slower than a synthetic mesh. But for chafe-prone wearers in humid climates, it solves a problem that most wicking underwear ignores.

Plus-size picks that don’t treat moisture control as an afterthought

Plus-size wicking underwear is often an afterthought in the US market — a size extension of a straight-size style, with the same fabric and construction that may not account for different moisture and friction patterns. The better options are brands that actually extend the gusset, adjust the waistband, and use fabric that does not roll or dig.

Goddess Keira Full Coverage Briefs are a solid moisture-wicking option in extended sizes, with a soft modal-cotton blend and a wide waistband. Harper Wilde’s Bliss Thong is a good thong alternative for plus-size wearers who want wicking without bulk. Fruit of the Loom’s Breathable line is the budget pick — it is not a performance garment, but the cotton-mesh briefs are inexpensive, breathable, and available in plus sizes with a 4.6-star average across more than 10,000 Amazon ratings.

Workout, Running, and Travel: Matching the Underwear to the Sweat Load

“Moisture wicking” is not a single use case. A pair that works for a 30-minute weight session may fail on a 10-mile run, and a pair that is perfect for travel may be overbuilt for a desk job. The smart approach is to match the pair to the sweat load and the drying environment.

Running: seams, inseam, and why “cooling” is not a gimmick

Running underwear has to handle sustained sweat, repetitive friction, and a high chance of chafing. The priorities are flat seams, a leg length that does not roll, and a fabric that dries fast enough to avoid staying damp between runs. For men, the Patagonia Sender Boxer Brief and SAXX DropTemp are both strong picks in the US market. For women, Reebok’s Suki Briefs and the Universal Performance Seamless Bamboo Thong have tested well for wicking and comfort over long miles.

“Cooling” fabrics are not pure marketing. Some synthetics are engineered with high thermal conductivity or a channeled structure that spreads heat and moisture across a larger surface area. The effect is modest, but it is real. The gimmick is when a brand slaps “cooling” on a dense cotton blend and charges $28.

Gym and lifting: support without compression-shorts dependence

For lifting, the underwear needs to stay in place during hip hinges, squats, and sled pushes. A pair with a wide, non-rolling waistband and a supportive pouch or gusset will outperform a loose boxer. Mack Weldon AirKnitx and Under Armour’s BoxerJock are both good for this use case: supportive without being a compression garment.

Women who lift often prefer a brief or boyshort with a higher rise to avoid the waistband rolling under a belt or lifting belt. Tommy John Air High-Rise and Athleta’s high-rise options are worth looking at if that is your priority.

Travel: wash-in-sink dry time and odor management

Travel underwear is a different sport. You want a pair that can be washed in a hotel sink, wrung out in a towel, and hung to dry overnight. ExOfficio Give-N-Go 2.0 is the benchmark here; it dries faster than almost anything else in the category. Merino is the other travel pick — it takes longer to dry but resists odor for multiple wears, which matters when laundry access is limited.

The travel mistake is packing heavy cotton or thick bamboo blends. They feel comfortable on day one and become a damp, smelly problem by day three.

TOP-5 Moisture Wicking Underwear Picks for 2026 (US Market)

These five picks cover the most common US use cases: everyday performance, heat and chafe, humid workouts, no-show women’s wear, and budget entry. They are not the only good pairs on the market, but they are the ones that consistently deliver on the wicking promise without requiring a leap of faith.

1. ExOfficio Give-N-Go 2.0 Sport Mesh — best overall for men and women

Why it wins: The most reliable combination of fast dry time, odor resistance, and durability in the US market. The mesh version breathes better than the standard knit, and the fit works across a wide range of body types. It is the pair to buy if you want one underwear for travel, gym, and everyday wear without thinking too hard.

Watch out: The fabric feels slightly slick, and the women’s sizing runs closer to a straight-size cut. Try one pair before committing to a multipack.

2. Duluth Trading Armachillo — best for heat and chafe resistance

Why it wins: The cooling hand-feel and long-leg options make it a standout for hot, humid days and anyone who deals with thigh friction. The waistband stays put, and the fabric holds up to repeated washing.

Watch out: Availability is limited compared to national brands, and the size range is not as deep as it should be for a brand with a workwear heritage.

3. SAXX DropTemp Cooling Mesh — best for humid, high-sweat days

Why it wins: The BallPark Pouch reduces skin-on-skin contact, and the DropTemp mesh is genuinely breathable in humid heat. It is a strong pick for men who sweat heavily and want mechanical separation, not just a fabric claim.

Watch out: Premium price and mesh durability is not as strong as ExOfficio’s nylon blend over multiple years.

4. Tommy John Air — best no-show women’s performance pair

Why it wins: The lightweight nylon-spandex fabric manages moisture and stays flat under leggings and fitted clothing. It is one of the few no-show pairs that does not sacrifice wicking for invisibility.

Watch out: Seam quality is inconsistent for the price, and the return policy on worn underwear is stricter than some competitors.

5. Uniqlo AIRism — best budget entry point

Why it wins: It delivers genuine wicking performance at a price that makes premium brands look nervous. The mesh version breathes well, dries fast, and packs small. For everyday wear and moderate workouts, it is excellent value.

Watch out: Slim fit, rolling waistband on some body types, and thinner fabric that will not last as long under heavy use.

The US Buyer Protection Reality: Returns, Warranties, and “Free” Shipping

Underwear is a hygiene-sensitive category, and US return policies reflect that. Most brands will not accept worn underwear unless there is a defect or a specific “try one pair” guarantee. That is not a conspiracy; it is a public-health regulation and a reasonable business practice. But the details matter, and the marketing around “free returns” deserves a closer look.

Underwear hygiene rules: what you can and cannot return

The general rule in the US is that underwear must be unworn, unwashed, and in its original packaging with tags attached to qualify for a standard return. Some brands go further: ThruDark, for example, will not accept returns once the packaging has been opened, citing hygiene reasons. Others, like SAXX through Zappos, accept unworn items with the protective adhesive strip intact.

The exceptions are the “try one pair” guarantees. Tommy John allows a refund or exchange for one worn garment of each type if you are not satisfied. UXL’s “30-Day Best Pair Guarantee” covers one opened pair while unopened items remain eligible for return. These policies are genuinely useful, but they are brand-specific and often require you to contact customer service rather than use a standard return portal.

Brand-by-brand return windows worth knowing

Nordstrom offers a 90-day return window on Jockey items sold and shipped by Jockey, provided the items are in new condition with tags attached. Amazon’s standard return window is 30 days for most clothing, with free returns on eligible items, but the “free” label depends on the reason for return and the seller. REI’s membership program extends the return window to one year for members, which is one of the most generous policies in the outdoor retail space.

Tommy John’s standard policy is 30 days for unworn, unwashed products with tags. Duluth Trading’s “No Bull Guarantee” is more flexible, but underwear is still subject to hygiene restrictions. The safest approach is to buy one pair from a new brand, test the fit and fabric, and only then commit to a multipack.

The “free returns” asterisk

“Free returns” is the retail equivalent of a free sample at a warehouse store: it is free because the cost is baked into the price, the shipping threshold, or the fact that you will probably keep the item anyway. Amazon’s free returns are genuine for many eligible items, but the policy has conditions — some third-party sellers charge return shipping, and “free” may mean a drop-off location rather than a pickup.

The smarter move is to check three things before ordering: the return window, whether worn underwear is eligible, and who pays return shipping. A brand with a 60-day window and a $7 return label fee is often a better deal than a brand with a 14-day window and “free” returns that requires you to print a label at your own expense. Read the fine print. It is boring, but it is cheaper than a drawer full of underwear you cannot return.

How to Care for Moisture Wicking Underwear So It Keeps Wicking

Wicking performance degrades with improper care. The fibers do not stop being hydrophobic, but residue from detergent, fabric softener, and dryer sheets can clog the microscopic channels that move moisture. A pair that wicks well on day one can become a damp, clammy disappointment after six months of neglect.

Wash temperature, detergent, and the fabric softener trap

Wash wicking underwear in cold or warm water — not hot — with a mild, residue-free detergent. Hot water can damage elastane and shrink some synthetic blends. Fabric softener is the enemy: it coats fibers with a waxy film that reduces wicking and breathability. Skip it entirely. If you want softer-feeling underwear, buy a softer fabric, not a chemical coating.

Turn the pair inside out before washing to clean the gusset more effectively and reduce pilling on the exterior. Use a mesh laundry bag if you are washing expensive pairs with zippers or Velcro, which can snag the fabric.

Air dry vs. tumble low: what the labels actually mean

Most wicking underwear can be tumble-dried on low, but air drying extends the life of the elastane and preserves the fabric’s structure. Merino should always be air-dried; heat degrades the fiber and can cause shrinkage. Synthetics can handle low heat, but high heat will shorten their lifespan. If you are in a hurry, tumble low for 10 minutes and then hang to finish.

When to retire a pair

Retire a pair when the waistband stops recovering, the gusset develops permanent odor, or the fabric feels stiff and no longer dries quickly. A stretched-out waistband is not just annoying; it changes the fit and creates gaps where moisture and friction can build. Most well-made synthetic pairs last 1–2 years with regular wear and proper care. Merino may last longer if you rotate pairs and avoid high heat.

FAQ: Moisture Wicking Underwear Questions Buyers Actually Ask

Is moisture wicking underwear better than cotton for everyday wear?

For sweaty commutes, warm climates, and any activity that involves sustained sweat, yes. Synthetics and merino move moisture away from skin faster than cotton. For cool, dry conditions and low-sweat days, cotton is comfortable and breathable. The mistake is expecting cotton to perform like a technical fabric under sweat load.

Can moisture wicking underwear cause yeast infections or irritation?

It can if the fabric is non-breathable or the gusset is synthetic and traps moisture. Look for a cotton gusset, a breathable main body, and a fit that is not overly tight. Change out of sweaty underwear promptly, and avoid fabric softener, which can leave irritating residue.

How long does moisture wicking underwear actually stay dry?

It depends on the fabric and the sweat load. A thin polyester mesh can feel dry within minutes of a moderate workout, while a thicker nylon blend may stay slightly damp for longer. No fabric stays dry indefinitely under heavy sweat; the goal is to move moisture away from skin fast enough to avoid chafing and discomfort.

Do I need special detergent for moisture wicking underwear?

A mild, residue-free detergent is sufficient. Avoid fabric softener and dryer sheets, which coat the fibers and reduce wicking. If your water is hard, a small amount of white vinegar in the rinse cycle can help remove detergent residue, but do not use it with merino wool.

Is merino wool underwear worth the price?

For travel, cold-weather running, and anyone who prioritizes odor control, yes. Merino resists odor naturally and regulates temperature well. For hot, humid running where fast drying is the priority, a lightweight synthetic usually outperforms merino. Buy merino for the use case, not because it is expensive.

What is the best moisture wicking underwear for plus-size women?

Look for brands that extend the gusset and waistband, not just the size label. Goddess Keira Full Coverage Briefs and Harper Wilde’s Bliss Thong are solid options. Fruit of the Loom’s Breathable line is the budget pick. Avoid pairs with narrow gussets or stiff waistbands that roll or dig.

Can I wear moisture wicking underwear every day?

Yes. Many people wear wicking underwear daily, especially in warm climates or if they commute actively. The key is to wash after each wear, avoid fabric softener, and rotate pairs so the elastane has time to recover. For low-sweat days, a breathable cotton or modal pair is perfectly fine.

Final Verdict: Buy for the Sweat You Actually Have

The best moisture wicking underwear is the pair that matches your actual sweat load, not the one with the loudest marketing. If you run hot and live in a humid climate, prioritize a thin, breathable synthetic mesh with flat seams and a supportive fit. If you travel and hate doing laundry, ExOfficio or merino will serve you better than a budget multipack. If you want no-show performance under leggings, accept that you will pay more for a pair that stays put and dries fast.

Ignore the “cooling” claims that come without a fabric explanation. Ignore “free returns” that require you to pay for shipping. And ignore the idea that one pair can do everything. Buy two or three pairs for different use cases, test them, and keep the ones that actually keep you dry. Your crotch will thank you. The rest is just marketing.
