After checking some reviews on Amazon I think I'm going to try the
ExOfficio Men's Give-N-Go Boxer Brief
They appear to be cheaper than they normally are, and I read a convincing review from someone who said he prefers them over the Under Armours. I've never paid this much for underwear, but it sounds like they will last for years. I'm now realizing that part of my problem with my underwear getting wet is that I don't always remember to put a seat cover on my bike. Thus the seat gets wet from sitting in the rain. I do wipe it off with either my shirt or a paper towel, but I think some of the rain seeps into the seat, making my crotch wet. I'm thinking a wicking underwear like this will really help the problem. I know, I know, it's my fault for not covering my seat, but I forget half the time, especially if it's sunny in the morning and rainy in the afternoon.
