You have been hiking for an hour, and then you feel it: the burn on your inner thighs, the soggy fabric clinging to your skin, the waistband digging in under your pack belt. The wrong underwear can ruin a day of backpacking faster than any boot blister. The right pair stops chafing, dries fast after a river crossing, stays in place mile after mile, and resists odor when you are multiple days from a shower. The New Balance Performance Boxer Briefs are the top pick for most hikers because their 6-inch inseam (the length from the crotch to the leg opening) stays put and prevents ride-up, which buyers consistently confirm. For high-heat trips with breathability as the priority, the ExOfficio Give-N-Go 2.0 Sport Mesh is the better call; for the ultralight packer who counts every gram, the 32 Degrees Cool Active saves real weight.

This guide sorts through six contenders to find the best backpacking underwear for men based on real-world performance and verified buyer feedback.
How To Choose The Best Backpacking Underwear For Men
The specs that matter on a trail are different from what you’d look for in daily wear. Here’s what separates a good pair from a hike-wrecking one.
Fabric: The First Line of Defense
You want synthetics like polyester or nylon blended with spandex for stretch. These wick moisture away from your skin and dry fast when you rinse them in a stream. Cotton is your enemy on the trail — it holds sweat, stays wet, and causes chafing that can ruin your trip.
Inseam Length: Finding the Sweet Spot
A 3-inch inseam keeps you cooler in hot climates and dries faster, but a 6-inch inseam offers more coverage and prevents the legs from riding up under your hiking shorts. Choose based on your climate and whether you hate bunching more than you hate a little extra fabric.
Odor Control: The Multi-Day Factor
On a week-long trip, you’re not doing laundry every night. Anti-odor treatments help the fabric resist bacteria growth that causes smell. Look for brands with proven treatments, but know that no treatment lasts forever — eventually it washes out.

In‑Depth Reviews
1. New Balance Men’s Performance Boxer Briefs with Fly
$19.98as of Jul 7, 2:46 PM6-inch inseam makes this the top pick for hikers who want a boxer brief that stays put under shorts all day without constant adjustment. The 6-inch inseam prevents ride-up and stays in place, which matters when you want to focus on the climb, not your underwear.
Each pair in the 3-pack weighs about 83 grams (250 grams total), so you are not adding noticeable weight to your pack. The 90/10 polyester-spandex blend gives you 360-degree stretch for unrestricted movement when you scramble over rocks, and the moisture-wicking fabric draws sweat away from your skin so you stay dry during high-exertion climbs.
The catch is that a few reviewers wished the leg was slightly longer for even more security, but for most hikers the 6-inch length hits the sweet spot between coverage and cooling. If you want a proven trail performer that holds up wash after wash without riding up, this is the one to beat for its price on a 3-pack.
Why it’s great
- 6-inch inseam prevents ride-up on long hikes
- Moisture-wicking fabric keeps you dry on climbs
- Soft no-dig waistband for comfort under a pack belt
Good to know
- Some buyers wish the leg were slightly longer
- Medium thickness may not dry as fast as ultra-thin options
2. ExOfficio Men’s Give-N-Go 2.0 Sport Mesh Boxer Brief 3″
$32.50as of Jul 7, 2:46 PMCompared to the New Balance pick with its 6-inch inseam, the ExOfficio Give-N-Go 2.0 runs shorter at 3 inches — making it cooler in hot climates and faster to dry, but you trade coverage for ventilation. One loyal buyer called it the “best boxer briefs available for decades” and reported that his 8 pairs, all 5 years old, show no wear or holes, which speaks to the durability backing its higher price.
In humid Florida heat or on a sweaty summit push, the sport mesh fabric breathes significantly better than standard polyester blends, and the improved anti-odor treatment keeps you fresher on multi-day stretches. The 4-way stretch and flatlock seams reduce chafing under a pack strap, and the wide waistband won’t stretch out over a week of wear.
Skip the New Balance if you run hot or hike in a humid climate — the 3-inch length is your ally, letting air circulate and drying fast when you rinse it in a stream. This is for the hiker who puts breathability and longevity over thigh coverage.
Where it shines
- 3-inch inseam is cool and fast-drying in heat
- 20+ year user base with pairs lasting 5+ years
- Improved anti-odor treatment for multi-day use
Worth noting
- Tags are notoriously hard to remove without damaging seams
- Runs large; buyer with 32-33″ waist should size down to Small
3. OYGSieg Men’s Boxer Briefs with Fly and Total Support Pouch
$19.99as of Jul 7, 2:46 PMPicture this: you are on day four of a trek and the only water you have is for drinking — you are not washing underwear. The OYGSieg 5-pack gives you enough pairs to rotate without resupply, and buyers report that the support pouch (a built-in mesh liner that separates and supports your anatomy) works and keeps everything comfortable, which matters when you carry a heavy pack all day.
The value math is straightforward: you get five pairs for roughly what premium brands charge for two or three, so you can pack a full week’s worth without the sting. The moisture-wicking fabric, flat seams, and functional fly all serve a backpacker well. One reviewer called it “perfect for the price” and noted minimal ride-up.
If you are budget-conscious and need a bulk solution for extended trips without resupply stops, this is your move. The newer brand (2025) has limited long-term durability data, but for the price, you can afford to replace them.
What stands out
- 5-pack provides week-long rotation without washing
- Support pouch reduces chafing under pack load
- Odor control effective after all-day wear
The trade-offs
- Sizing may run snug; consider sizing up for looser fit
- Newer brand (2025) with limited long-term durability data
4. 32 Degrees Men’s 4 Pack Cool Active Boxer Brief
$24.99as of Jul 7, 2:46 PMWeight per pair: 3.6 ounces — the lightest in this lineup. The 32 Degrees 4-pack totals 14.4 ounces, and its “Cool Fabric” is designed for optimal airflow to keep you ventilated even under a midday sun.
The downside at this weight is durability: the thin fabric dries incredibly fast (owners mention hand washing dries by morning) but may not last as many seasons as heavier-duty options. One trail-tested reviewer called them “best travel briefs ever” because they pack small and dry overnight.
Pick these over the Wrangler if you count pack weight in ounces (you save about 1.5 ounces per pair) and need gear that dries before dawn. They are not the toughest, but for the ultralight backpacker, that is the right price-to-value read.
The upsides
- Ultralight at ~3.6 oz per pair saves pack weight
- Hand wash dries by morning for back-to-back days
- 4-way stretch moves with you on the trail
Keep in mind
- Thin fabric may not last as long as heavier blends
- Limited front room; some buyers size up for comfort
5. Wrangler Men’s Cooling Boxer Briefs, 6” Inseam
$47.99as of Jul 7, 2:46 PMAt this lower price you get a 6-pack of boxer briefs built from 91% nylon — a tougher, more abrasion-resistant material than polyester, which matters when your underwear rubs against pack straps and coarse shorts all day. Customers note these are “great, dry quickly, don’t hike up much and stay cool,” confirming the 6-inch inseam does its job.
The cooling and moisture-wicking technology works in both heat and cold — the fabric pulls sweat away from your body so you stay dry in summer and do not get chilled by wet fabric in winter. The gusset (a diamond-shaped reinforcement panel at the crotch) allows full range of motion, and the stretch fabric provides support without feeling restrictive.
If you put gear through hard miles and expect it to last multiple seasons, the nylon construction gives you a durability edge over polyester-heavy competitors. The trade-off is they come in multi-color packs, not solid colors, if you prefer a uniform look — making this pack perfect for the budget buyer who prioritizes long-term toughness over a uniform drawer.
Why we’d pick it
- 91% nylon fabric resists wear and abrasion
- 6-inch inseam keeps legs from riding up
- Cooling technology works in hot and cold conditions
A few caveats
- Color options limited to multi-color packs
- Heavier than polyester alternatives
6. SAXX Underwear Co. Men’s Multi-Sport Mesh Boxer Brief Fly 3-Pack
$62.95as of Jul 7, 2:46 PMThe SAXX Multi-Sport Mesh is for the hiker who has tried everything and still chafes. The patented BallPark Pouch separates and supports so nothing rubs together — reviewers point out that with these, chafing is not a problem anymore, and you do not even need to powder.
For that price you get a 3-pack of mesh-ventilated, moisture-wicking boxer briefs with flat out seams that disappear against your skin, a no-roll waistband, and no-ride-up legs that one reviewer noted require zero adjustments while sitting, walking, running, biking, or hiking. The feedback is consistent: soft, breathable, supportive without restriction.
If you have struggled with chafing on every trip and are sick of body glide and powder, SAXX solves the root problem rather than managing the symptom. The price stings upfront, but the peace of mind on a 20-mile day is worth it — just be prepared for the highest cost per pair of any pick here.
Strong points
- BallPark Pouch eliminates chafing at the source
- No-ride-up legs require zero adjustments all day
- Breathable mesh keeps you cool on high-output hikes
Before you buy
- Premium price per pair is the highest in this guide
- Some buyers find them too warm despite mesh ventilation
Understanding the Specs
Fabric Composition
The blend of polyester, nylon, and spandex determines how the underwear breathes, dries, and stretches. Polyester wicks moisture well and dries fast, nylon is tougher and more abrasion-resistant, and spandex provides the stretch that lets you move freely. A higher spandex percentage (10-15%) means more freedom of movement, while higher nylon content means more durability against pack straps.
Inseam Length
Measured from the crotch to the leg opening, this determines how much coverage you get. A 3-inch inseam is shorter and cooler with faster drying time, but a 6-inch inseam provides more security against ride-up. Your choice depends on whether you prioritize ventilation or want to eliminate mid-hike adjustments.
Moisture Wicking vs Quick Dry
Moisture wicking pulls sweat away from your skin so it can evaporate, keeping you dry during activity. Quick dry refers to how fast the fabric itself dries after getting wet — critical when you wash your underwear in a stream and need it ready by morning. Both are essential, but they’re different metrics: a pair can wick well but dry slowly if the fabric is thick.
Anti-Odor Treatment
Many active underwear brands apply a proprietary treatment to the fabric that inhibits the bacteria growth responsible for smell. This is valuable on multi-day trips when you’re wearing the same pair for 3-4 days between washes. The treatment does fade over time with washing, so the best approach is to check reviews for how well the odor control holds up.
