Patagonia reduces relative humidity in your shorts with the Men's Active Boxer Brief. These boxer briefs feature wicking Capilene fabric that moves moisture and heat away from your skin, so you don't overheat. Trail running, climbing, and backcountry skiing all become more comfortable in Patagonia's fitted boxers. With its smooth surface, Capilene won't bunch or ride up, and this underwear works wonders under hiking shorts or even suit pants.

Will the Patagonia Active Boxer Brief - Men's shrink after wash and drying?

Responded on

Nope, doesn't shrink at all. Synthetic fibers (like polyester) hold their size, so no worries there.

these fit well. but loosen up after a few hours of wearing. they are also very susceptible to body funk. i am a pretty clean dude when it comes to personal hygiene, but these will still always get that funk by days end. the best i have found for outdoor pursuits (fit and ability to stay fresh) are actually calvin klein micro modals

Hi, guys. There is a question about size....

Hi, guys. There is a question about size. I'm 177cm(5.8ft) tall, 65KG, and my waist is 83cm (between 32-33in). I should be fine with M according to patagonia sizing chart and my CK boxer is M too. However, I'm slim guy and I feel good in S with Icebreaker and Arcteryx long bottom underwear (not boxer etc.)

Should I stay S or go for M as sizing chart suggeted? I'm new to Patagonia product.

Honestly I think you'd be happy with either size, it just depends how snug you want em. Sizing seems pretty versatile, I have both medium and large in these and don't dislike anything about either and both are comfortable. Hope that helps more than confuses...

go with the briefs

Because they're better. These are alright too. I don't believe the guy that said he wore them for a week and didn't have any odor issues, maybe I have bad smelling sweat. Then again it could have been the curry chicken I had the night before. LOL.

Alright, here is my dilemma. I got my cold weather skivvys down, but looking for some hot summer time ones. From walking around the city to hiking on the trails in the summer, will these work to help the counteract the swamp?

Responded on

These are the best skivy's I've found to counteract the swamp - for sure. Super comfortable and quick drying, you can't go wrong w these.

Sad Day

I bought 2 pairs of these 2 years ago right before studying abroad in Viet Nam. They are very very comfortable, breathable but noticeably thin. I was concerned about this when I initially bought them but decided to trust patagonia's reputation. This past fall I noticed holes have developed in the crotch due to normal wear. For this reason I would not buy these again. Yes it took a year and 1/2 for them to develop this wear but wore them at most 1 a week and my 3 for a dollar cotton boxer briefs that I have had for twice that time have yet to wear through. Come on patagonia I expected more for a $30 a pair premium!

The Best Undies Ever

i bought a pare of North face boxer briefs. These ones blow them out of the water. the north face took forever to dry unlike these and i think that these are so much more comfortable

Excellent briefs

I've been a fan of the regular Patagonia capilene boxers for years, but these are great under jeans and work pants.

Didn't know boxers could be so comfortable

These are definitely the most comfortable boxers I have ever worn. They stay in place but have enough stretch to move with you. They do a great job of moisture and temperature regulation. Worth every penny.

based on the size chart, i would wear a...

based on the size chart, i would wear a small (30" waist). But, at 6'1" i'm on the slightly tall side for that waist size and, when going strictly on waist size with other boxers, i have found the inseam to be too short. does anyone have a recommendation as to whether i should order small or medium?

Best Answer Responded on

I think a medium in the Active Boxer Brief would do well for you. I'm 6'1 and a 32 waist and the large fits me fine.

Ya Get What Ya Pay For

I thought there was no way I was going to like these more than my UnderArmour briefs, but I was wrong. Now I'm kind of peeved that I bought as much UA as I have. These are more comfortable than UA and don't stretch out as much during wear. They're cooler and not as restrictive. If any underwear can be called "great", these are the ones.

so smooth

pricey, but effective. I have worn these from everything to weddings to trails + they keep you feeling cool + comfortable.

Although gross, upon purchasing my first pair I wore them 5 days straight as a pseudo-field test. They stood up great + after a sink wash they were ready to hit day 6 + beyond...

Perfect fit. Very comfortable. More affordable then other others such as Smart Wool. Purchased a second pair because I liked them so much.

Ok, let's face it; while many think its simply gross many of us guys go commando. I have been f433b@11in for many years. Recently, however, I have been contemplating on getting me a pair of boxers like these. Since it seems after many reviews of various brands that these are the recommended best my only question is it like cramming your three friends in a Honda CRX or a luxury Civic? Please, any quick advice on this would be greatly appreciated cuz I'd like to order some pretty soon for a thru hike. I can deal with returning insoles even, but I don't think I'd want to be on the recieving end of anyone's skivvy returns, lol!

thanks in advance!

Responded on

If you are worried about cramming the boys into something so tight you will need a can opener to use the bathroom, I would look to a model/brand that uses two different fabrics. Some brands use a more relaxed material around the family jewels so they are not so compressed. This gives you the best of both worlds, underwear that won't ride up and some room for the boys.

Responded on

These aren't especially tight at all, ended up being more like boxers than boxer briefs

Responded on

Much less restrictive than any other boxer briefs I've tried (UA in particular) - they keep their shape, don't ride up, never feel clammy or sticky, and dry out quickly. They don't SEEM like they'd be that great, but I prefer them over anything else I've worn.

To be honest, these are OK. I have tried just about every pair of non-cotton boxer brief on the market, and while these may come in third place, the Ex Officios and Under Armour BoxerJocks are both far superior to these in comfort and performance.

how do these do with odor? I am planning on going on a week long hiking trip and do not want to take many clothes.

Responded on

I have not worn these in particular, but the 'new' Capiline (Cap 1, 2, 3) resists odor much better than the older stuff (silkweight, lightweight, midweight).

(sorry it's not a great answer, but i figured some info was better than none)

Responded on

well, my friend, I can say that these will smell. I used them on my Appalachian Trail thru-hike where I would go a week or two without washing my clothes. These were my camp boxers, so I didn't wear them while hiking, but after a while they start to smell. The great thing about them is they are incredibly easy to rinse out in a river -- and then you're golden!

Responded on

They do great. I wouldn't expect them to smell washer-fresh after seven days, but they shouldn't reek to bad after a week. They are synthetic so they will start to gain critical bacterial mass after a while, but they are also anti-microbially treated to help out with that. They are super light and super-packable, so you could stash a spare pair to switch out to, or, since they dry incredibly fast, you could wash them out one night, hang them up under your shelter and be good to go by morning (which is what I do.) For synthetic underwear, these are still my favorite hiking and travel undershorts, bar-none.

form fitting

I have two different pairs both of the same size and they dont fit the same. However I do prefer how they fit for hours of walking/running at a time. I've even worn these under cycling shorts ( I dont know why ) and was very happy with them. I like that they are light and have a small form-factor in your diddy/pack bags, much better then the REI MTS layers..
