SmartwoolMen's Merino 150 Boxer Brief

These are the best boxer briefs on the market! Soft, comfortable, don’t ride up, and retain their shape unlike other merino boxers.

I really wanted to not like these because of the price, but these are by far the best pair of underwear I have ever worn. They are super soft, they fit perfectly (no bunching, riding up, etc.), and they manage sweat and heat perfectly. I just returned from 5 days in the swamp that is Hong Kong in the summer, and these were much more pleasant to wear than regular cotton boxers.

I am a six foot, six inch guy who goes on lots of back country adventures. I purchased these to explore moving from synthetic clothing to natural fibers. After a summer backpacking trip in the Colorado wilderness and a rafting trip down the Grand Canyon, I am very impressed with these boxers. Smartwool definitely lived up to their sterling reputation with these boxers.Washing them in rivers and lakes got them clean, though the washing was out of habit. They were odor free and didn't cause any chaffing or crotch-rot. After a few months of wear and washing, they are showing minor wear faster than cotton or synthetic underwear. The wear does not affect comfort or performance. I dry them on a hanging rack overnight and they are dry by that time.I will continue to buy these boxers as they are an excellent solution to my high adventure underwear needs.

I've tried lots of different types of boxer briefs. The Winners and Losers are (in order):Winners: SAXX Undercover, SAXX Vibe, Izod Lacoste Cotton. I wear these regularly.Honorable Mention: Tommy John Cotton, Izod Lacoste Cotton Modal, Ex Officio Give-N-Go Sport Mesh, Izod Lacoste Motion Micro Mesh. I wear these also, but not quite as often.Losers: SAXX Platinum, Smartwool Merino 150, Mack Weldon, SAXX Kinetic, SAXX Shadow Boxer, SAXX Ultra, Hanes Ultimate. I no longer wear these.My criteria are simple. (1) They must keep me in place. The Winners, Honorable Mentions, and all of the SAXX brand do that. The others do not. (2) They must be comfortable. The winners are all comfortable. The Tommy John Cotton and Izod Lacoste Cotton Modal (honorable mention) are also very comfortable. The rest of the honorable mentions are comfortable but less so. From the loser group, the Smartwool was very comfortable as was the Mack Weldon. They just didn't keep me in place. (3) They must keep me cool. The winners all do that though the heavier Izod Lacoste Cotton can get a bit warm in the summer. The honorable mentions also do that except for the Izod Lacoste Motion Micro Mesh, which were a bit warm, but fine in the winter. The Smartwool and Mack Weldon also were cool, they just didn't keep me in place. The rest were not comfortable. Either they didn't feel right next to my skin or they were just too hot. (4) They must keep their shape and wear well over time. The winners all do that. The honorable mentions all do that except for the Tommy John Cotton and Izod Lacoste Cotton Modal which tended to wear quickly. This is the only thing that kept them from the winners group. Those in the loser group all wore well and keep their shape. The lost out either for not keeping me in place or comfort (too hot or didn't feel good next to my skin).

These are comfortable most of the day standing and walking. These are not good for long drives or sitting at a desk for long periods. Tend to do a little bunching and binding.

Good quality

Very soft and comfortable. Ordered Large and fit great on a 36" waist.

I have had 5 pairs of these underwear for about 6 months and I REALLY wanted to like them.They feel nice and hold everything in place.But, they are very thin, you can see straight through them and they are not durable.Almost all of them have sections were the weaving is splitting apart and a couple of them have open holes in them. I do not believe I am some extreme user of underwear, and yet in 6 months ive managed to "wear out" all 5 of these underwear when my prior ones looked as new as the day I bought them.ALSO, I paid 30$ a pair, I see now the price has gone UP BY FIFTY PERCENT TO 45$. At 30, I am now hesitant to pay that after my experience, but at 45 it is now not worth it at all.There are more luxurious available brands at that price point.I wanted to love these, but smartwool has failed me, and I fear they will fail you. And at 45$ per pair, that's quite the failure.

My boyfriend really likes this underwear for his hikes.

Merino is my best choice for travel underwear - long or short. Very comfortable, I have worn it from about -10C to +45C. Washes easy by hand and dries in 4-6hrs in warm and dry conditions. Hang straight and don’t need (critical for travel). I travel with 3-4 pcs and wash about every other day. Very expensive for underwear, but helps travel light, comfy and clean. Hint: avoid underpants without front opening if using motorcycle or ski or similar suits/overalls.

Sounds strange but these wool boxers are great for wicking the sweat away on hot long days keeping your jewels cool and chaff free whilst hiking in the mountains. They are also quick drying.

Doux mais pas 100% laine comme dit dans le descriptif.

They keep me 'very comfortably' where I need to be and are superb quality.Fred
