I've spent the last few years wearing underwear from these guys 24/7, and they are the most comfortable and colorful underwear I've ever owned. MeUndies are designed in L.A. and made from sustainably sourced MicroModal -- a fabric three times softer than cotton. And now, they are also offering socks made from some of the most comfortable, premium materials. If you don't love your first pair of MeUndies, they'll hook you up with a new pair or a refund. Check out MeUndies.com/Tim to see my current faves (some are awesomely ridiculous, like the camo) and get 20 percent off your first pair.
