My boy friend claims these are life changing. I’ll take his word for it

Very comfortable fabric, but as someone with debilitating swampass this doesn't do enough to dry, even with gold bond. 4 stars because it almost gets there, but not quite. Other brands I tried for dryness were exofficio and uniqlo airism. Airism has been the winner by far for me, but it is practically sheer and probably isn't warm enough for colder environments. I'd say go with this in the colder outdoors, go with airism for warmer indoors climates.

It is super thin and breathable. Hoping it would last. The fit is great but it is definitely expensive.

I love Smartwool Merino products. As a backpacker I try to use as much Merino Wool as possible and as much as I feel I can afford. So far the Sport 150 Boxer Briefs have been comfortable, wicked up moisture, dried quickly, felt comfortable, and like all wool products seem to reduce body odor. One thing I missed in ordering mine and that is the lack of a fly. I can make them work, but I have never understood why they would be omitted in men's briefs. It will not prevent my using them. It is too early to know how they will hold up. As Merino Wool products are expensive, I hand-wash or machine wash delicate in cold water with Woolite and then tumble dry on low heat.

If you have thick legs, the material will rub under very normal use and you’ll get holes pretty quickly. For the money I expected better.

These shorts fit and feel wonderful with all the added benefits of merlino wool and they’ll serve you well as long as you treat them gentle when washing. Always wash them on medium or gentle cycles and do NOT put them in the dryer. Hang dry them only and I guarantee they will last twice as long. Also, NATURAL SOAP only. Synthetic detergents will eat this fabric up in no time. They are expensive but if you treat them well they will treat you well and pay for themselves with care.

Pros: Very comfortable underwear. They feel great. Cons: 1. Purchased these in March and, even after following all of the smartwool guidelines on washing and drying, they developed holes in the crotch 2. Contacting smartwool about their guarantee via there customer service has resulted in zero resolution- even after following their guidelines. It is a shame because I like smartwool socks, but I won't be purchasing anymore smartwool products as their "guarantee" is nothing more than a slogan to lull consumers into buying their sub standard products. Update: Smartwool got back to me with an update and giftcard to replace the faulty merch. It makes me happy that they are good to their word so upped the star count.
