Rated 4 out of 5 by from Waste-Band colors (Blue and Green)? I understand the colors used on the waste-band for the Blue and Green are Smartwool's logo colors, but why isn't it like this for the Light Grey and Taupe(glad they didn't because I like the Light Grey color with the black waste-band better)? Personally I don't care for the waste-band color scheme of the Blue and Green, because it stands out like a sore thumb when visible... My (2) Pattern prints and (1) solid boxer briefs developed holes and tears 6 months in and were replaced under REI 1yr exchange policy. I have to say I do like the wider waste-band and the way they lined the inside with merino wool fabric, and find the newer design better than the previous years

Rated 5 out of 5 by from I bought one of each color! Yes, they are expensive but the husband loves them. They last, are nice and soft, and durable. Great for extended outdoor trips. Easy to wash and quick to dry. Very light weight too (compared to those conventional cotton boxers).

Rated 5 out of 5 by from Most comfortable briefs I've ever used! Period... Not much more to say. They stay cool and dry, keep you warm and cool. They make me tempted to swap out my entire underwear collection for merino wool underwear. They are that amazing!

Rated 5 out of 5 by from Good for an all wool outfit I love wearing these with wool pants as they help you keep the full benefits of wearing wool baselayers and outer garments in the winter.

Rated 5 out of 5 by from Love Synthetic underwear makes for stinky nether-regions - not so with wool! Love these.
