My favorite

    Between these and the Smartwool Hiphuggers - I have gone back and purchased several pairs. I love them. I rinse them after hiking for the day and they're dry and like-new in the morning. The only thing that I don't like about these compared to the SmartWools is that there's a little bit of extra fabric in the back for me and I have an average (if not bigger) booty. Overall though, these are great!

    Like this underwear but....

      I am 5'6", 130 lbs and usually wear M in clothes. The S in these fit. I also wear S in Patagonia underwear. I bought the Icebreaker underwear because I loved the Icebreaker retreat tank so much and decided to try the underwear. They are comfortable but feel a little loose/insecure compared to the Patagonia underwear I usually wear which is more stretchy and snug fitting- I use these for everyday wear, but don't know how they would do for exercising - ie would they stay in place...

      search is over

        I've tried a LOT of brands of underwear, and these are finally absolutely right. I took two pair with me for four months on the Pacific Trail, they lasted like new and were so comfortable always- heat, wet, snow, the works. Wash and dry fast, in fact wearing them wet after swimming they dry really fast while you hike. And best of all, I can forget I have them on, they fit that well. I'm 135lbs. most of the time, and 5'6", size medium in these. Now I never wear any other kind.

        The BEST!

          Yep, amazing... great fit, hold up well ( I don't put mine in the dryer) and very comfortable. They stay put and don't ride up or fall down. Best thing is they don't hold odor, so never stinky even after a trek. Fast drying, so easy to rinse when traveling. They may be expensive, but worth EVERY penny!


            Not itchy at all even though it's at the most sensitive area. Perfect fit; not tight and not loose. Soft yet sturdy. Also the curved style is extremely flattering. I can't believe I spent thirty bucks and I'm going to spend another thirty on another pair. It's that good.
            Update: I'm not sure why but a hole developed right in the middle in the front, where nothing rubs against it. Hopefully it's just one pair with this problem.

            I'm wondering about size: I usually wear a L in icebreaker shirts, but my "low hip" is 40 in, which according to the size chart for these says a M. Anybody have suggestions about fit?
