Patagonia Silkweight Boxer Briefs Reviews:

Positive Reviews:

Do you remember Riverdance? Michael Flately with his tights on and his puffy shirt.. Oh my... These man panties make you feel like you are part of the action. You may look absolutely normal on the outside with your clothes on but underneath you'll have the feeling of being a Celtic warrior princess. It is quite the feeling.
I never understood how those dancers could last so long tapping and jigging away like they did until I slid a pair of these on. There I was jigging and tapping my way throughout the house to the amazement and shear wonder of those viewing the spectacle. When I finally stopped and had the peace of mind to put the rest of my clothes on I was amazed at what I would find... They kept my balls dry. Any other man panty I own wouldn't have done that. So I have to say these are impressive.
Do you know the leading cause of male fumunder cheese production? That's right.. Sweaty nut sacks. No one enjoys being in a tent with someone with ripe nuts.. But they do enjoy a little entertainment. So Riverdance your way to a dry sack and be the talk of your next outing.

Next-to-Skin Comfort, Wicking, Worth it!

Buying my first pair of Silkweight Boxer Briefs was a mistake in that I immediately learned how awful and cheap-quality my other boxers were in comparison! I quickly picked up additional colors and prefer these as my go-to boxers for running and everyday activities. As a runner, it's nice to finish a 10, 15, 20+ mile run in the heat and, upon taking these boxers off, noticing that my skin is dry! When pulling them out of the wash, they are nearly dry if that gives you an idea on how insanely fast wicking these are. I tried to capture the stitching and complexity of the waist-band weave in the picture. I am a male with a 29-30 inch waist and the size Small fits perfectly. Note they do take a little bit to break in but you want them hugging your skin for optimal performance. These things fit like a second skin. I usually wait until their sales either in store or online and pick them up for half-price and would recommend them even at full price.

I've worn these every day for the last 15+ years (well, not the same pair, and I have washed them...), so I can legitimately say I've "put them through the wringer." If you are wondering why I am typing so smoothly right now, it is because of my Silk Weight Patagonia briefs. They are that good.
Butt seriously, 2-3 star reviews? I love those things and would much rather get a new pair or two every year instead of a paisley tie. They are comfy and loose fitting in the right places, while being snug around your hips so they don't fall down.
A friend of mine claims he can wear them for a week at a time and they don't stink. I don't know if I'd go that far, but they are a very nice set of boxers. I'm going with a 5 out of 5 on these.

Andrew McLean at on 03/14/2013

I am partial to wool boxer briefs. All this talk of "wicking" has never seemed to be a reality for me. After a while, synthetics seem to feel clammy around the inner thigh and my junk. Furthermore, synthetics are torture on dry winter hands (nails on a chalkboard kind of thing). So, I prefer wool boxer briefs (few make them, and they are expensive). But wool can get, in summer I prefer superfine cotton (which is also expensive). All that said, this is literally an excellent pair of synthetic boxer briefs. I like the feel (like silk) and the fit is so good that I might simply keep them in the rotation. I am here reviewing them because I want to stock up.

Fine for sports

I didn't have last years version to compare. But I picked these up specifically for use in acrobatic sports. Though the legs are on the tight side and ride up, once thy get there, I have no problem with the comfort, I wanted them to keep things in place, and the do a great job of that. Of course being SW Cap. they also do a great job of moisture control which is vital for any kind of sport use. I'm giving 4 starts, fix the legs and it's 5, but no reason not to use these. Also FWIW, I don't like the SW Stretch at all for briefs, there is something about them that feel cold down there.

Smoother than silk

It's been a while since I purchased Patagonia boxer's after struggling to get a good fits for over the last five years (prior to that I have worn Patagonia silk boxer's for more than a decade). Nevertheless, these Boxer Brief fit great. I think it's because they are brief's and still conform to my body. They are great to wear under bike riding shorts without bunching up. Overall, the silk weight is cool enough or comfortable to wear without getting to hot compared to other polyester kinds of shorts. I bought them on sale and would have bought more if I know that they felt so good.

fit bigger this season, need to make XS

Hey, patagonia i love the improved fabric and slightly bigger thighs (exactly what i would suggest to improve on last seasons) but the small now fits questionably more loose then the old medium... they are cut bigger and since they stretch out easier also its a big difference especially in the support offered while active. I use to wear either the small and mediums depending on the activity but now the small it too big. Please, offer extra-small of make the small smaller next season! These are my favorite briefs otherwise!
ChristopherTheClimber at Patagonia on 02/08/2012

Very Comfortable

These feel very supportive, yet don't bind. Up until recently, I had always worn the short briefs. I tried out some Patagonia boxers, and really like sleeping in them, but they didn't feel supportive enough during the day, and because they are baggy, they bunched up under jeans or regular pants. These strike a happy medium,and I like them.
JohnnyB at Patagonia on 03/31/2012

Last seasons' were better

I love the silkweight boxer briefs from last season. These are still pretty good, but they are tighter than last season (which were perfect for me.) They are branded on the rear so if you bend down you'll be repping patagonia. These are still great--lightweight, wedgy-free, dry fast, and breathe well. I will not ever return to cotton.
MikeyMike at Patagonia on 08/25/2012

Great Fit

Obviously, fit will vary for everyone. These boxers happen to fit me great, and are very comfortable. I bought them for my backpacking trips, but wear them all the time. More comfortable for me than Ex Officio and REI briefs. They also dry very quickly, which is great after those dips in the river/lake.

Negative Reviews:

Tight, no stretch, so much worse than last year's

Last year's silk weight boxer briefs were awesome, dried super fast, had the normal amount of stretch you'd expect from boxer briefs. These things on the other hand are bizarre, it's like they picked a fabric for boxers, that has just about zero stretch and made them in a boxer brief cut, they're uncomfortable to wear just walking around, they ride up. Doing any sport in them is down right unpleasant. I'm a big Patagonia fan, they normally put so much thought into their gear, but this one is just a total loser. On the strength of last year's, I mail ordered two of this new kind, I wore one pair, washed them a couple times and I hate them, still have the other pair in the bag, and I think it's too late to return, I'd sell them on eBay or something, but I think whoever bought them would just complain and give me bad feedback. Rating these a 'Don't buy'!
citybiker at Patagonia on 04/08/2013

Don't bunch up, but too hot

I ordinarily like Patagonia products, but not these (unfortunately, I bought a bunch). I travel a lot and hike a lot; I want something the washes well, dries well, is comfortable, and wicks sweat. I don't like cotton boxers that become sweat boxes; unfortunately, that's what these become. It's great quality and I'm stuck with these for a long time, but I recommend the Ex Officio brand instead of these. These are not vented, the silk-like material smears sweat instead of wicking it, and they are hot. Great for sleeping in though; but they are too expensive ultimately.
Von Wandurer at Mountain Gear on 06/06/2013


6'0 170 lbs The fit is strange on these. I have the caps in a large, the lightweight boxer briefs in a large and these weird diaper things in a large. While the plain caps and the lightweights are the best thing ever and feel great. These make you feel like something weird is going on down there. The legs are too tight while the waist is loose. Ummm why? And the crotch area just feels funky and it feels like I'm in a diaper.
Sacredmonkeyman at Patagonia on 03/17/2013

Not the Same

I have been enjoying these boxers for years, but am afraid I have to agree with those who find the latest version a major disappointment. Unlike the old boxers, which had a nice drape and feel, these are form fitting and constricting; not really boxers at all. It's not strictly a matter of size; it appears the design has changed. Hard to understand why the company would alter a proven winner for the worse. Will not repurchase until product matches former standards.
Dash at Patagonia on 02/12/2014

Surprisingly bad

Agree with the other reviews -- the 2013 versions of these boxer briefs that I've purchased are horrible. Very tight, not much stretch, very little breathability. These pale in comparison to briefs from just the year before. Patagonia, I used to love these (5 stars, easily). What happened?!
tacobean at Patagonia on 07/24/2013

Maybe the next size up?

I wear a Medium in the Lightweight Boxer Briefs and gave the silkweight boxers a try during a recent sale. The fabric has little stretch and I could barely fit them over my hips, while I can wear the Lightweight Boxers comfortably, YMMV...
Julian at Rock/Creek Outfitters on 09/09/2013

Neutral Reviews:

Along with the previous reviewer, I feel that these are contricting(and I'm skinny).
It feels like they didn't cut it to accommodate for any leg movement. Raise your leg too high, and it starts to constrict.
Aside from that, they do wick moisture very well. I also used them for swimming trunks recently, and they dried in a snap.
It's not too bad... but I wouldn't buy any more of these

Emerson Takahashi at on 01/12/2013

Streamlined review here.....
Fit: true to size (always wear a Medium, and the M in these fit fine)
Material: moisture wicking for sure, but NOT as stretchy as I'd wanted/hoped for....a bit constrictive for me, and this is where "3 stars" comes from.
Overall: for the price, I was hoping for more...the overall fit of 'em and the lack of elasticity just make these adequate in my opinion.....go for Ex-Officio instead.

stridemon at on 01/11/2013

I love the silkweight boxers, so I figured I'd give these a try. I found a medium to be super tight--like, sausage casing tight (pun intended)--I'm 6'0, 160lbs, 32" waist, so I figured a medium would be plenty roomy, which was not the case. That said, they do stretch, which helps. I still wear them, but overall, I'll stick with the boxers from here on out.

wyap454541 at on 01/27/2014

tight on leg

I have owned several pair of these Boxer Briefs and love them but the last pair I ordered were tight in the leg area, seems like the cut was changed. this causes them to ride up and bunch where you don't want them to bunch. If you have legs like a distance runner you will be fine, sprinter not so much
tommytaha at Patagonia on 07/29/2012

sized smaller

I love the silkweight boxers and have had a pair or two of the boxer briefs in the past, but recently got two more, and they fit VERY tightly. You may want to consider sizing up or a cold shower prior to putting them on. All of their other undies sized as expected and are fantastic
Wyoerik at Patagonia on 10/06/2013

Poor fit

Agree with citybiker and some others that these just fit weird. I can definitely deal with the fit and I still wear them but they are my least favorite pair of patagonia underwear. It feels like if these had some spandex in them to give some stretch they would be a whole lot more comfortable.
PTdawg at Patagonia on 06/11/2013

I've owned Patagonia Silkweight Boxers for years and they are by far and away my favorite, but these are "briefs" meaning they have the same pattern, but are tight fitting. Not quite what I was hoping for, and as a matter of pride, I'm not going to return underwear. ;)

Andrew McLean at on 01/29/2014

smooth and comfy!

I have some cap boxers that I really like and the medium fits fine. However the med silkweights are a lil snug....its OK. Great for running or working out. Feel more like a compression brief. I give it 3 stars because I was expecting more of an underwear feel.
Rangerglx at Patagonia on 03/11/2013

Jury's still out

I purchased these because I find the modern Patagonia SW boxers to be cut too full and the waist band likes to double over on itself. While ok, these briefs don't seem to be the answer. They tend to bunch up and I have felt some slight chafing.
kaceman at Patagonia on 03/17/2012

Expensive but will last for a long time
