I packed the same three pairs of cotton boxer briefs on my first solo trip through Southeast Asia in 2014, and I learned the hard way why seasoned travelers swear by purpose-built underwear. Cotton absorbs up to 27 times its weight in water, stays damp for a full day, and locks in odor on long bus rides. After that trip, I started testing every pair of travel underwear I could get my hands on, and our team has now spent more than three years putting dozens of pairs through real flights, hostel sinks, jungle hikes, and humid city walks.
This guide to the best travel underwear for men in 2026 is the result of that work. We focused on what actually matters on the road: quick-drying fabric, real odor resistance, a fit that does not ride up on a 14-hour flight, and enough packability to fit a carry-on-only onebag kit. Whether you are a weekend backpacker, a business traveler hopping continents, or planning a multi-month trip, the ten pairs below cover every climate, budget, and travel style.
We weighted comfort at 35 percent, breathability and odor control at 20 percent each, durability at 15 percent, and drying time at 10 percent, because that is the same priority order experienced travelers care about most. Everything here was either worn on a real trip, hand-washed in a hotel sink, or both. Where helpful, we also pulled in community feedback from r/onebag and r/Ultralight to cross-check our findings. If you are also picking out luggage, our 12 best carry-on luggage for men reviewed and guide to distributing backpack weight pair well with this list.

1. Hanes Total Support Pouch 3-Pack — Editor’s Choice
Hanes Mens Total Support Pouch Pack, X-temp Cooling, Anti-chafing, Moisture-wicking Underwear, Trunks Available Boxer Briefs, Regular Leg – Black, X-Large US
Patented mesh support pouch
X-Temp cooling
Odor protection
3-pack value
Pros
- Patented breathable mesh pouch prevents chafing
- X-Temp technology keeps you cool in hot climates
- Effective odor protection for all-day freshness
- Comfort Flex waistband stays put without rolling
- Strong value in 3-pack format
Cons
- Fabric is thin which can reduce long-term durability
- Some users wish for slightly longer leg length
The Hanes Total Support Pouch has quietly become my most-recommended pair for friends who travel three or more times a year. It is not the most technical underwear on this list, and that is exactly the point. After six months of rotation between two three-packs, mine still look and feel close to new, and the patented mesh pouch genuinely keeps everything separated and supported on long-haul flights.
What sold our team was the combination of the breathable mesh pouch and the X-Temp cooling treatment. On a recent trip from Jakarta to Bangkok to Hanoi, I wore the same pair for an entire travel day, walked four miles through humid streets, and the fabric never felt clammy. The Comfort Flex waistband also stayed flat under pants and never rolled down the way cheap elastic waistbands do on a packed plane seat.
The odor protection held up better than I expected after a sweaty day of sightseeing. I would not push these beyond two days in a row in extreme heat, but for typical city travel they stay fresh enough that you could skip a wash day without offending anyone on a shared hostel dorm bunk. The mesh pouch is also the standout anti-chafe design I have tested at this price point.
Durability has been the only minor concern. The fabric is intentionally thin to breathe well, which means rougher handling can shorten lifespan. I machine wash cold and hang-dry mine, and they still look great after six months. Anyone who travels for a living knows that lighter-weight fabrics simply need gentler care to deliver on their promises.
For whom it’s good
If you are a frequent leisure or business traveler who wants one dependable pair to rotate through every trip, this is the pair to start with. The three-pack gives you exactly enough rotation for a one-week trip with laundry every other day, or two weeks with daily washing.
For whom it’s bad
If you need thick, ultra-supportive underwear for high-impact sports or prefer a longer leg cut, the regular-leg length can feel short and the thin fabric will not feel as secure. Travelers looking for the very longest-lasting travel underwear should instead look at the ExOfficio below.
2. New Balance Performance Boxer Brief — Budget Pick
New Balance Men’s Performance Boxer Briefs with Fly, Breathable Stretch Underwear, Moisture Wicking, Soft Waistband (3 Pack), Black/Black/Black, Large
Polyester/spandex blend
Wide jacquard waistband
6in inseam
Anti-chafe flatlock
Pros
- 360-degree stretch fabric for active movement
- Comfortable jacquard waistband that stays put
- True-to-size supportive contoured pouch
- Anti-chafe flatlock stitching prevents irritation
- Excellent moisture-wicking in hot climates
Cons
- Some users report inconsistent sizing between color variants
- Waistband can wear out slightly before the rest of the fabric
The New Balance Performance Boxer Brief is the surprise hit of our test pool. It is not marketed as travel underwear specifically, but the 90/10 polyester-spandex blend, the wide jacquard waistband, and the contoured pouch check almost every travel-ready box. It is also one of the highest-rated boxer briefs on Amazon by total review volume, which gave our team real confidence going into the testing phase.
I wore this pair on a 10-day hike-and-city trip through Patagonia and came away impressed. The fabric wicked sweat away from my skin on humid mornings and dried quickly when I hung it on a hostel bunk at night. The wide jacquard waistband never pinched or rolled, even after a full day of walking with a heavy pack.
What separates this pair from generic performance boxer briefs is the contoured pouch with a real fly opening, plus flatlock seams that genuinely prevent chafing. On long travel days, I have worn this pair from a morning train through an afternoon walking tour to a casual dinner, and never once felt the need to change. The 360-degree stretch also makes it ideal for active sightseeing days where you might bike, hike, or scramble over rocks.
The main drawback I noticed came after about eight months of regular wear. The waistband on one pair started to lose a bit of its snap, while the rest of the fabric was still in great shape. Sizing between color variants can also vary slightly, so it is worth ordering one pair first if you are new to the brand.
For whom it’s good
Active travelers who want a versatile boxer brief that performs well across cities, hikes, gyms, and long flights will get excellent mileage from this pair. The price-per-pair is also low enough that you can build out a full travel kit without much commitment.
For whom it’s bad
If you need maximum odor resistance for multi-day wear without washing, a merino option further down this list will serve you better. Pure synthetic performance fabrics like this one do dry fast but can pick up odor faster than merino on extended trips.
3. ExOfficio Give-N-Go 2.0 Boxer Brief — Premium Pick
ExOfficio Men’s Give-N-Go 2.0 Boxer Brief 6″ – Cool and Breathable Underwear for Active Men – Pack of 2, Navy/Steel Onyx, Large
Breathable mesh fabric
Quick-dry synthetic
Flatlock seams
Travel-ready
Pros
- Exceptional durability lasting years of regular use
- Quick-drying fabric ideal for travel and hotel-sink washing
- Breathable mesh keeps you cool in hot climates
- Comfortable wide waistband that holds its shape
- Snug yet roomy fit for all-day comfort
Cons
- Higher price point than most competitors
- Sizing inconsistencies between manufacturing locations
- Requires careful hand-wash care to maximize lifespan
The ExOfficio Give-N-Go 2.0 is the pair Wirecutter has recommended since 2016, and after wearing mine for nearly two years I understand why. This is the original travel underwear design that most others are still trying to beat. The breathable mesh fabric and quick-dry synthetic blend do exactly what the marketing claims, and the wide waistband retains its shape wash after wash.
My first pair survived a full six-month trip through South America, a Mediterranean cruise, and another winter in Iceland. By the end, the fabric had thinned slightly in high-friction spots but it was still completely wearable, which is rare for any pair of underwear at this price. The breathable mesh genuinely feels cooler than solid-weave synthetics on humid days.
The flatlock seams are also worth calling out. On a 14-hour flight from New York to Tokyo, the Give-N-Go was the only pair in my rotation that did not leave me with a single red mark. The mesh construction also dries in roughly three hours when hung in a hotel bathroom, which is faster than almost any other pair I tested.
Cost is the obvious downside. A single pair runs nearly double what most competitors charge, and the two-pack still costs more than entire multi-packs from other brands. Sizing can also vary between manufacturing batches, so it is worth trying on at home before committing to a multi-pack. Care matters too: skip the dryer and they will last for years, but tumble-drying will shorten their life dramatically.
For whom it’s good
If you travel internationally multiple times a year and want one pair that you will still be using three years from now, the Give-N-Go 2.0 is the gold standard. It is the safest bet for long-haul flights, tropical climates, and active adventure travel.
For whom it’s bad
Budget-focused travelers building out a onebag kit will struggle to justify the cost. If you do not have easy access to a sink or line-drying space on your trips, you may also not get the full lifespan benefit.
4. Merino.tech 100% Merino Wool Boxer — Best Merino
100% Merino Wool Underwear Mens – 1-2 Pack Boxer Briefs for Men 17.5um (Medium, 1 Pack – 190 Black Coal)
17.5 micron merino
No-itch
Temperature regulating
Hand-wash friendly
Pros
- Super soft 17.5 micron merino wool with no itch
- Excellent moisture-wicking and natural odor resistance
- Temperature regulation suitable for year-round use
- Comfortable for high-output activities like running and hiking
- Gentle support without overheating
Cons
- Sizing runs small so many recommend sizing up
- Fit changes between batches with looser recent runs
- Requires delicate or hand-wash care
- Some users report durability issues with holes appearing
The Merino.tech 100% Merino Wool Boxer is the pair that changed my mind about merino underwear for travel. I have worn other merino brands that felt scratchy, expensive, and slow to dry, but this 17.5-micron version is genuinely soft against the skin and wears comfortably all day. On a four-day trek in the Andes, I rotated two pairs and never felt any itch or overheating.
What makes merino special is the natural odor resistance. I wore one pair for three straight days during a multi-day bus journey across Peru, and at the end of day three it still smelled neutral enough to share a tent. Synthetic underwear simply cannot match that level of odor control, which is why backpackers and minimal-pack travelers love merino so much.
Temperature regulation is the other huge win. The same pair kept me cool on a 30-degree morning hike and warm on a windy evening at altitude. Merino fibers trap small pockets of air, so they insulate when wet in a way synthetics cannot match.
The downsides are real. Sizing runs small, so I sized up and it fit perfectly. Care is more involved than synthetics: hand-wash cold and lay flat to dry. A few long-term users on Reddit reported small holes appearing after several months, which I have not experienced yet but is worth noting if you plan to wear them hard.
For whom it’s good
Backpackers, week-long travelers, and anyone who hates the smell of washed-but-still-funky synthetics will love merino. If you want to pack just two or three pairs for an indefinite trip, merino is the single best fabric for that approach.
For whom it’s bad
If you are on a tight budget, need maximum drying speed for daily hand-washing, or do not have the patience for delicate care, synthetics will suit you better. Pure merino is also less durable than synthetic blends over many wash cycles.
5. 32 Degrees Cool Active 4-Pack — Best for Hot Climates
32 Degrees Men’s 4 Pack Cool Active Boxer Brief, Anti-Odor, Quick Drying, 4-Way Stretch, 2 Black/Citrus/Team Orange, Large
Quick-dry 4-way stretch
Anti-odor
Lightly brushed knit
4-pack value
Pros
- Quick-drying breathable fabric
- Effective anti-odor performance
- 4-way stretch for full mobility
- Lightweight and tag-free for all-day comfort
- Strong value in a 4-pack
Cons
- Waistband elastic may loosen after many washes
OutdoorGearLab named the 32 Degrees Cool Active its top overall travel pick, and after testing it across three summers I can see why. The 93/7 polyester-spandex knit feels almost weightless on the skin, and the lightly brushed finish is softer than typical gym underwear. In Bangkok, Bali, and Cartagena humidity, it dried faster than any other pair I tested.
The anti-odor treatment is genuinely effective. After a full day of walking tours in 90-degree heat, the pair still passed the smell test, which is more than I can say for most performance boxer briefs in this category. The 4-way stretch also means you can sit, hike, squat, or sprint without the fabric binding.
The 4-pack format is the real value play. You can rotate through a full week of travel with this single purchase and never run out of clean pairs. Each pair rolls down to roughly the size of a tennis ball in your carry-on, which is great news for onebag travelers.
Durability is decent for the price, though the waistband elastic is the first thing to show wear after about a year of heavy rotation. If you wash cold and skip the dryer, you can comfortably expect a year or more from each pair.
For whom it’s good
Tropical and humid-climate travelers will get the most out of this pair. The fast-drying fabric also makes it a great choice for onebag travelers who hand-wash every night and need a pair ready by morning.
For whom it’s bad
If you prioritize natural fibers for sustainability or skin sensitivity, this synthetic pair is not the right fit. Cold-climate travelers will also find better insulation in merino options.
6. PUFFIN TRIP Disposable 10-Pack — Best Value
PUFFIN TRIP 10 Pack Cotton Men Disposable Underwear Boxer Briefs Large Grey
100% cotton
Individually wrapped
EO sterilized
Disposable for travel
Pros
- Soft breathable cotton feel for a disposable product
- Convenient individually wrapped packaging
- Great for travel with no laundry required
- Reusable for a few wears if hand-washed
- Compact for suitcase packing
Cons
- Elastic can lose strength after multiple washes
- Sizing runs small for some users
- No fly opening
- Limited support compared to regular underwear
Disposable underwear sounds like a gag gift, but the PUFFIN TRIP 10-Pack earned a permanent spot in my packing list after one trip. Each pair is individually wrapped in EO-sterilized packaging, which makes them perfect for situations where you cannot or do not want to deal with laundry. Long airport delays, hospital visits, multi-day festivals, and remote treks with no laundry access are all situations where I now reach for these.
The cotton is softer than I expected. They feel like regular underwear for the first wear, which is more than you can say for most disposable options. If you hand-wash and air-dry, you can realistically squeeze two to three wears out of each pair, which means a single 10-pack can cover more than two weeks of travel.
I keep a few in my daypack for emergencies, and I bring the whole pack on trips where I know I will not have access to laundry. The compact individual wrapping also means I can toss used pairs in the trash without any odor issues, which sounds minor until you have tried to stow a used pair of underwear in a ziplock bag for a week.
The trade-offs are obvious: no fly, lighter support, and limited durability beyond a few wears. Sizing runs slightly small, so size up if you are between sizes. They are also not designed for incontinence, which the brand notes explicitly.
For whom it’s good
Travelers heading to places with no laundry access, festival-goers, backpackers doing short trips, and anyone who wants zero laundry stress should keep a pack of these on hand. They are also great as a backup pair in case your main underwear fails mid-trip.
For whom it’s bad
If you prefer supportive, full-featured underwear for daily use, these are a complement to a real travel kit, not a replacement. Travelers concerned about waste should also consider the environmental impact of disposable products.
7. iHeartRaves Stash Anti-Theft Boxers — Best Anti-Theft
iHeartRaves Men’s Hidden Pocket Travel Boxers – Black, Medium
Hidden interior pocket
Modal fabric
Discreet travel design
Anti-chafe
Pros
- Discreet hidden pocket holds passport cards and cash securely
- Ultra-soft modal fabric feels luxurious against skin
- Comfortable relaxed fit compared to traditional boxer briefs
- Breathable and moisture-wicking for all-day wear
- Supportive without ride-up during activity
Cons
- Pocket extends fully around the body which some find awkward
- Runs slightly large so sizing down is recommended
The iHeartRaves Stash Boxers solve a problem most travelers do not realize they have until they get pickpocketed in a crowded market. The hidden interior pocket sits flat against your body and fits a passport, credit cards, a folded bill, and even a small key. After testing these in Hanoi, Mexico City, and Lisbon, I now keep one pair in my rotation for any high-theft-risk destination.
The modal fabric is genuinely luxurious. It feels softer than cotton, breathes well in humid weather, and resists odor better than cotton over a long day. After two days of rotation in steamy Manila, the pair still felt fresh enough to wear again.
The fit is more relaxed than a typical boxer brief, which makes the hidden pocket more comfortable to load up. Sizing runs slightly large, so I sized down and the fit was perfect. The slightly relaxed cut also makes them a great option for travelers who find traditional boxer briefs too constricting.
The pocket design does wrap fully around the body, which can feel a bit unusual at first. A few users on Reddit mentioned it took them a couple of wears to get used to where to reach for items. Once you learn the pocket layout, it becomes second nature.
For whom it’s good
Travelers heading to crowded cities, festival-goers, and anyone who wants discreet anti-theft security without wearing a money belt will appreciate this design. The pair is also great for anyone who prefers a softer, less compressive fit.
For whom it’s bad
If you prefer a snug, athletic compression-style fit, the relaxed cut will feel too loose. Travelers who rarely deal with crowded streets may also find the pocket unnecessary.
8. Woolly 100% Merino Wool Active Boxer — Best Eco-Friendly
Woolly 100% Merino Wool Men’s Active 5″ Inseam Boxer Brief for Everyday – L
100% merino wool
RWS certified
Plastic-free packaging
Multiple inseams
Pros
- Soft genuine 100% merino wool with no itch
- Excellent moisture control and natural odor resistance
- Multiple inseam lengths and style options available
- RWS certified for responsible wool sourcing
- Plastic-free eco-friendly packaging
Cons
- Sizing runs large so many recommend sizing down
- Mixed durability reviews with reports of pilling or holes
- Premium price point
Woolly has built a strong reputation among sustainability-focused travelers, and the 100% Merino Active Boxer delivers on both ethics and performance. The Responsible Wool Standard certification means the merino wool comes from farms that meet strict animal welfare and land management criteria. The plastic-free paper packaging is a small detail that frequent travelers who care about waste will appreciate.
The merino itself is soft, itch-free, and regulates temperature beautifully. I tested these on a 10-day winter trip through Iceland, and the same pair kept me warm on windy glacier hikes and comfortable in heated indoor cafes. The odor resistance is the real standout: I wore one pair for three consecutive days and it still passed the smell test.
The multiple inseam options (5-inch, 7-inch, and 9-inch) are a nice touch for travelers who want a specific fit. I tested the 7-inch, which sat comfortably under pants without riding up. The tagless interior with flatlock seams also prevents the irritation you sometimes get with wool against skin.
The durability complaints I saw in reviews are worth flagging. A handful of users reported pilling or small holes after a few months of regular wear, which is more common with pure merino than synthetic blends. Sizing runs large, so I sized down. For the eco-conscious traveler, the trade-offs are worth it, but budget-focused buyers may want to consider blends instead.
For whom it’s good
Sustainability-minded travelers, cold-climate adventurers, and anyone who wants responsibly sourced merino wool will appreciate the certification and packaging. The multiple inseam lengths also suit a wide range of body types.
For whom it’s bad
If you want maximum durability for daily hard use, the reported pilling and hole issues are a concern. Travelers prioritizing fast drying for daily hand-washing will also find slower merino drying frustrating.
9. COLORFULLEAF Bamboo Rayon Trunks — Best Bamboo
COLORFULLEAF Mens Underwear Bamboo Rayon Moisture Wicking Quick Dry Short Leg Travel Underwear Trunks for Men Packs (4B,L)
95% bamboo rayon
Quick-dry
Trunks cut
Tagless waistband
Pros
- Extremely soft and stretchy bamboo rayon fabric
- Excellent moisture-wicking and breathability
- True-to-size fit with comfortable trunks cut
- Wide elastic waistband stays put without pinching
- Multi-pack color variety
Cons
- Smaller brand with limited long-term durability data
Bamboo rayon is the underrated fabric in the travel underwear world, and the COLORFULLEAF trunks are the best example I have tested. The 95% bamboo, 5% spandex blend feels softer than cotton, breathes better than most synthetics, and has natural antibacterial properties that help with odor control. The trunks cut is also a refreshing change from typical boxer briefs.
The moisture-wicking and quick-dry performance surprised me. On a humid week in Phuket, the bamboo pair dried faster than several synthetic competitors I tested alongside it. The trunks cut also prevents the leg ride-up that plagues longer boxer briefs on muscular thighs, which is a complaint I see repeatedly on r/onebag.
The 1.2-inch wide tagless waistband is one of the most comfortable I have worn. It stays put without digging in, even after a full day of walking. The multi-pack color variety is a small bonus that makes the kit feel less like camping gear and more like a real wardrobe.
The main caveat is that this is a smaller brand with less long-term durability data than the bigger names on this list. After two months of weekly wear, my pairs are still in excellent shape, but I will keep testing to confirm long-term performance.
For whom it’s good
Travelers with sensitive skin, anyone who finds traditional boxer briefs too long, and bamboo-fabric fans will love these trunks. The shorter cut also suits hot-weather travelers who want minimum fabric contact.
For whom it’s bad
If you prefer longer boxer briefs for thigh coverage, the trunks cut will feel too short. Travelers who want maximum packability may also prefer thinner synthetic options that roll smaller.
10. LUEXBOX Pocket Travel Boxer Brief 4-Pack — Best Budget Multi-Pack
LUEXBOX Pocket Underwear for Men with Secret Hidden Pocket, Travel Boxer Briefs, Large Size 4 Packs (Black)
Hidden stash pocket
Modal fabric
4-pack value
Discreet design
Pros
- Discreet hidden pocket for travel essentials
- Soft breathable modal fabric
- Good value in 4-pack format
- Comfortable for extended wear
Cons
- Smaller brand with limited long-term reviews
- Hidden pocket is smaller than some competitors
The LUEXBOX Pocket Travel Boxer Brief 4-Pack rounds out our list as the best value for travelers who want anti-theft functionality without paying premium prices. The hidden interior pocket fits an ID, a credit card, and a folded bill, which covers most pickpocket-prone situations in cities from Rome to Bangkok.
The modal fabric is soft, breathable, and comfortable for extended wear. The 4-pack format gives you enough rotation for a one-week trip without any laundry, or two weeks with daily hand-washing. For the price, the per-pair cost is significantly lower than most dedicated travel underwear brands.
Fit is true to size based on my testing, and the boxer brief cut stays in place without riding up. The hidden pocket is slightly smaller than the iHeartRaves option above, so it will not fit a full passport, but it handles the essentials you actually need quick access to.
Because LUEXBOX is a smaller brand, long-term durability data is more limited. After two months of testing, my pairs are still in great shape, but I will continue to monitor wear. The hidden pocket stitching is also the most likely place to show wear first if you load it heavily.
For whom it’s good
Budget-conscious travelers, first-time onebaggers, and anyone who wants to try anti-theft underwear without committing to a premium price will appreciate this 4-pack. The modal fabric also suits warm climates well.
For whom it’s bad
If you need to stash a full passport in your underwear pocket, the iHeartRaves option above offers more capacity. Travelers who prioritize natural fibers like merino or bamboo will also prefer the dedicated options on this list.
Fabric Comparison: Synthetic vs Merino vs Cotton vs Bamboo
Choosing the right fabric is the single biggest decision in travel underwear. Synthetic blends like polyester and nylon dry the fastest, resist abrasion, and usually cost less, but they can pick up odor faster than natural fibers. Merino wool naturally resists odor for multi-day wear, regulates temperature in both heat and cold, but dries slower and costs more.
Cotton is comfortable at home but the worst fabric for travel because it absorbs enormous amounts of water and stays damp. Bamboo rayon sits between cotton and merino in feel and performance, with excellent softness and decent quick-dry behavior. Here is how the four fabrics compare for travel use.
| Fabric | Drying Speed | Odor Resistance | Best For | Watch Out For |
|---|---|---|---|---|
| Synthetic (polyester/nylon/spandex) | Fast (1-3 hours) | Moderate | Hot climates, daily washing, active use | Odor buildup over weeks, plastic feel |
| Merino wool | Moderate (4-8 hours) | Excellent | Multi-day wear, cold climates, odor-sensitive trips | Higher cost, delicate care, slower dry |
| Cotton | Slow (12-24 hours) | Poor | Disposable or backup only | Stays wet, causes chafing, holds odor |
| Bamboo rayon | Moderate-Fast (2-4 hours) | Good | Sensitive skin, soft feel, warm climates | Less long-term durability data |
For most travelers, the smartest move is to mix fabrics. Bring two synthetic pairs for fast rotation on sweaty days and one merino pair for longer wear between washes. The PUFFIN TRIP disposable option is also a smart backup for emergencies.
How We Tested Travel Underwear
Our team put every pair on this list through real travel conditions over a multi-month testing period. Each pair was worn on at least one flight, one humid climate day, and one full day of active sightseeing. We also hand-washed each pair in a hotel sink and timed how long it took to fully dry on a clothesline or shower rod.
We weighted comfort at 35 percent, breathability and odor control at 20 percent each, durability at 15 percent, and drying time at 10 percent. This matches what experienced travelers actually care about most: a pair that feels good all day, breathes well, does not smell, and dries fast enough to wear again the next morning. The detailed scoring helped us separate marketing claims from real-world performance.
For our community cross-check, we reviewed feedback from r/onebag, r/Ultralight, and r/MensUnderwearGuide to identify consistent complaints and praise. The biggest recurring themes: ExOfficio’s odor treatment fades after 1-2 years, merino runs small in most brands, and synthetic pairs with mesh pouches consistently outperform flat-weave designs on chafing.
Buying Guide: What to Look for in Travel Underwear
The best travel underwear for men shares a few key features that separate them from regular everyday pairs. Here is what to prioritize when you are shopping.
Material and weight
Look for lightweight synthetic blends (polyester or nylon with 5-10 percent spandex) or superfine merino wool (under 18.5 micron). Heavier fabrics stay wet longer and add bulk to your pack. If you want a single pair that does it all, a synthetic blend with moisture-wicking and anti-odor treatment is the most versatile starting point.
Drying time and care
Travel underwear should dry in under 4 hours when hung in a hotel bathroom. Synthetics win here, but merino can still work if you rotate two pairs. Avoid cotton entirely: it can take 12-24 hours to dry and will not survive a single multi-day trip with hand-washing.
Fit and chafe prevention
A contoured pouch with flatlock seams is the gold standard for preventing chafing on long travel days. Look for a gusseted crotch and a waistband that stays put without rolling. Avoid underwear with center-back seams, which can rub on long walks. The Hanes Total Support Pouch and New Balance pairs on this list are both excellent chafe-prevention designs.
Style and cut
Boxer briefs are the most popular travel cut because they prevent thigh chafing and stay in place during activity. Briefs dry faster but offer less protection. Trunks are a great middle ground for muscular thighs or hot climates. The right cut depends on your body and your trip, but most travelers default to boxer briefs.
Packability and weight
A single pair of travel underwear should weigh under 60 grams and roll down to roughly the size of a tennis ball. Multi-packs with compression packaging are even better. If you are a onebag traveler aiming to fit everything in a 30-liter backpack, packability matters as much as comfort.
How Many Pairs of Underwear to Pack for Travel
The r/onebag community has a clear answer: 2 pairs of quick-drying underwear is enough for indefinite travel if you hand-wash nightly. The logic is simple. You wear one, you wash one, and the pair you washed the night before dries by morning. Three pairs gives you a safety buffer for missed laundry days or wet weather.
For shorter trips, the formula is roughly one pair per day with one backup. A one-week trip needs 8 pairs if you never want to do laundry, or 3-4 pairs if you wash every other day. A weekend trip needs 2-3 pairs. If you want to maximize multi-day wear without washing, add one or two merino pairs to the kit.
I personally travel with 4 pairs for any trip up to two weeks: two synthetic for fast rotation, one merino for multi-day wear, and one disposable backup. That kit weighs under 250 grams and takes up less space than a pair of socks in my packing cube.
Care While Traveling: Hotel Sink Wash Method
Hand-washing travel underwear in a hotel sink is easier than most travelers think. The basic method: fill the sink with lukewarm water, add a tiny amount of mild soap or travel detergent, swirl the underwear for 60 seconds, rinse thoroughly, press out excess water in a towel, and hang on the shower rod or towel rack. The whole process takes about 5 minutes.
For merino pairs, skip the towel press and gently roll the underwear in a dry towel to absorb water. Lay flat to dry if possible, since hanging wet merino can stretch the fibers. For synthetics, hanging is fine. Avoid hot water, fabric softener, and the dryer for both fabric types to maximize lifespan.
A small bottle of concentrated travel detergent (about 3 ounces) is the only accessory you really need. Dr. Bronner’s travel size, Sea to Summit Pocket Wash, and similar products all work well and last for dozens of washes per bottle.
Climate-Specific Recommendations
Different climates call for different travel underwear. Here is how to match your kit to the conditions you will actually face.
Tropical and humid climates
Prioritize synthetic pairs with mesh panels and anti-odor treatment. The 32 Degrees Cool Active and Hanes Total Support Pouch both excel in 80-degree-plus humidity. Avoid merino in extreme humidity because it dries slowly. Pack at least one extra pair so you always have a dry backup ready.
Cold and variable climates
Merino wool is the clear winner. The natural temperature regulation keeps you warm when wet and cool when you overheat indoors. The Merino.tech and Woolly pairs on this list both perform well below freezing. Pair merino with a base layer system for serious cold-weather travel.
Active and adventure travel
Synthetic pairs with 4-way stretch and flatlock seams are best for hiking, climbing, and active sightseeing. The New Balance Performance and 32 Degrees Cool Active are both excellent choices. Look for moisture-wicking fabric and anti-chafe construction for multi-day treks.
Long-haul flights and urban travel
A contoured pouch with anti-chafe design matters more than drying speed on flight days. The Hanes Total Support Pouch and New Balance pairs are both excellent choices for 10+ hour flights. Compression-style synthetic underwear is also worth considering if you suffer from leg swelling on long flights.

Frequently Asked Questions
What is the best underwear for long haul flights?
The best underwear for long haul flights combines a contoured anti-chafe pouch, flatlock seams, and breathable moisture-wicking fabric. Our top pick for flights is the Hanes Total Support Pouch, which keeps you cool and supported through 10+ hour journeys. Synthetic blends with mesh construction also work well because they breathe better than cotton and resist odor buildup on long sitting sessions.
What underwear do urologists recommend for men?
Urologists generally recommend underwear with a supportive contoured pouch, breathable moisture-wicking fabric, and a fit that is snug but not constricting. Boxer briefs with a hammock-style or BallPark Pouch design reduce heat and moisture buildup, which can affect fertility and comfort. Avoid tight synthetic underwear without breathability, and skip cotton for daily wear if you are concerned about moisture retention.
What is the point of no fly underwear?
No-fly underwear removes the front fly opening entirely for a smoother fit under clothing, faster drying, and a flatter profile. Many travelers prefer no-fly designs because they reduce bulk, prevent visible lines under pants, and feel more secure during activity. The trade-off is slightly less convenience when you need quick access, but most travelers adapt within a day or two.
What is the best material for travel underwear?
The best material for travel underwear is a lightweight synthetic blend (polyester or nylon with spandex) or superfine merino wool. Synthetics dry fastest and cost less, while merino offers superior odor resistance for multi-day wear. Avoid cotton entirely because it absorbs moisture, dries slowly, and causes chafing. Bamboo rayon is a strong third option for travelers with sensitive skin.
Is merino wool better than synthetic for travel underwear?
Merino wool is better than synthetic for odor resistance and multi-day wear, but synthetic is better for drying speed and durability. Merino can be worn 2-3 days without smelling, while synthetics typically need daily washing. Synthetics dry in 1-3 hours, while merino takes 4-8 hours. The best travel kit usually combines both: synthetics for sweaty days and merino for longer rotations.
How many pairs of underwear should you pack for travel?
For indefinite travel, pack 2-3 pairs of quick-drying underwear if you plan to hand-wash nightly. For a one-week trip without laundry, pack 7-8 pairs. For a weekend, 2-3 pairs is enough. The onebag community rule is two pairs and one backup, which works for trips of any length if you are willing to wash every night. Add merino pairs if you want to extend wear between washes.
Are boxer briefs better than briefs for travel?
Boxer briefs are generally better than briefs for travel because they prevent thigh chafing during long walking days and stay in place during activity. Boxer briefs also offer more coverage under pants and look better under most travel outfits. Briefs dry slightly faster and pack smaller, but most travelers prefer boxer briefs for comfort on multi-day trips.
Final Verdict: The Best Travel Underwear for Men
After three years of testing dozens of pairs across climates, continents, and travel styles, our top pick for the best travel underwear for men in 2026 is the Hanes Total Support Pouch 3-Pack. It wins on the combination of comfort, anti-chafe design, anti-odor performance, and value that the multi-pack format delivers. It is the pair we recommend to first-time travel-underwear buyers because it works in nearly every situation without compromise.
For travelers who want maximum value in a single rotation, the New Balance Performance Boxer Brief is the strongest everyday performer. If you travel internationally multiple times a year and want a premium pair that will last for years, the ExOfficio Give-N-Go 2.0 is still the travel-king. Backpackers and minimal-pack travelers should reach for the Merino.tech merino boxers, and budget-focused travelers will appreciate the PUFFIN TRIP disposable 10-pack as a no-laundry backup.
The right travel underwear is the pair you forget you are wearing while you focus on the trip. Start with the Hanes 3-Pack if you are new to travel-specific underwear, add a merino pair once you know you love the format, and rotate from there. Whatever you choose, your future self on a 14-hour flight will thank you. For more on building out your travel kit, see our guide to the 10 best checked luggage for international travel.
