Wow. Never in my wildest dreams did I think I would review underwear - but these deserve a shout-out. Weary of traveling with endless pairs of plain cotton underwear that chafed, rode up, trapped heat, and never dried out after washing overnight, I invested in two pairs of these after reading some reviews. Let me tell you: these are a better investment than most of those in your mutual fund. They were cool, soft, and virtually undetectable - I literally forgot I was wearing them. They never, ever rode up. The fit is perfect. And, when washed, they dry out in a matter of hours. I took two pair on a 8-day trip to Central America. I could have gotten away with just bringing the pair I showed up in. For anyone who travels, hikes, camps, paddles - this is the only underwear to have.
