Thought I'd try their undies since I live in Texas and it is hotter than hell right now. Went on a 200 mile ride today in temperatures that ranged from 95 to 100. These are better than advertised. I was wondering if my purchase was worth it......yes, without a doubt. Want a t-shrit now. If you ride in hot weather do your butt and cajones a favor, spend the money and keep 'em cool.
