Customer Reviews Smartwool Merino Sport Boxer Brief

Sweaty, itchy bum in the summertime? Not with these bad boys! The wool puts all other fabrics to shame, SO breathable and fast drying that you could literally pee your pants in them and still be comfortable. You'll never want to wear another kind of underwear.

Super comfortable boxers, the fit is great. They don't bunch up and seem to hold their form really well.

Daily wear, hiking they wick away moisture so you stay dry. Best I have ever worn

Very comfortable for everyday wear.

Most comfortable pair of underwear I think I've ever had. Great even in a warm climate. I think they run a little big, I tend to wear a medium in everything and in these I'm a small.

Comfortable, dry quickly after sweating. #sweepstakes

Comfy & light

I love Smartwool socks so I thought I would try the boxer briefs for running. So far very good. Comfortable and no thigh chaffing.

Super comfy and just great all around

Most comfortable underwear I've ever owned. Just with they had a fly

Used when participating in action sports. I like the fact that waist bands don't stretch out before the briefs wear out. Most other brand lose their elasticity and are a lot narrower. Smart wool brand are a lot more comfortable and durable.

I bought these for a 3 day BC ski hut trip and they worked great. Good fit. Comfortable fabric. Didn't notice them, which is kind of the point.

I absolutely love these underwear for their fit, attractiveness, comfort, warmth ( or cooling!), moisture wicking, and functionality for an avid outdoor athlete. The fit is sleek and supportive. I'm of the camp that is glad there is not excessive room in the baggage compartment because I feel more secure in my activities. Following that logic, I am also really pleased there is no fly. There are a lot of pros and maybe one con* to that, but again I like the sleekness and support of not having an open piece of material. It's just a nuisance (*I guess, until it's not?). These wash well, are lightweight, very breathable, and merino just feels so much better for underwear than the usual nylon/polyester/spandex blends. And you can wear them year round because they are cooling, wicking, and breathable. Plus, wool is naturally antimicrobial/antibacterial. Like others have said: try them. You'll never go back to anything else.

Love these boxer briefs. Purchased 6 pairs ab 18 months ago and when it was time to replace, no question that I got some more! Great for camping/hiking and really all activities. #sweepstakes

Very comfortable all around. Hugs the junk just right.

I use the product as underwear...not as a mask as has been rumored before. They work very well as underwear. Not so well as a mask, which I have never tried to do.

I got one of each color in a medium for my partner (mwho is normally a Small/32 ish on pants/bottoms sizes but always seems to be tugging at his waistbands on his older boxer briefs so I figured a medium would help keep him from pulling on them and it works! They fit great, little extra room in the butt so he's got motivation to do those BOOTY SQUATS and not too tight on the waistband, love the purple Heather color but the black and grey are super safe, would be cool to see other colors but I could only afford 3 anyway.

Excellent fit and comfort. Use for hunting and hiking outings. True to size: I'm 5'7" & 167 #'s and waist: 35", the large fits perfect.

It took me a long time to pull the trigger on a pair of these and months ago opted for a set of organic cotton undergarments. While those were still a good product for the most part these wool boxer briefs have outclassed my originals by far. Love the feel against skin, I used the sizing chart and it was very accurate for my fit. Very pleased and plan on purchasing more.

A little softer material than the "non sport" boxers. Great fit without squashing the boys.

Husband found them comfortable

These are very comfortable. I run 60 miles a week and I never get chaffing. Furthermore they last.

Taking these boxers to Nepal for trekking! Have worn them in the Rocky Mountains and will be taking them to the Himalayas. Not constricting, size is accurate, comfortable and do not smell when on a long hike. I'll be buying three more pairs asap!

As comfortable as the others, but didn't notice here lack an opening.

Rides up a little bit.. but for the most part, very soft and a good athletic fit.
