No pinches cotton chonies!!!
Get some wicking synthetic underwear from a manufacturer like Wickers, or Terramar, or Under Armor. Get the boxer style, they fit tighter than regular boxers and are stretchy. They pull the sweat away from your skin instead of absorbing it like cotton does.
You can get them here:
Sierra Trading Post I've found the Terramar to be some of the best fit and quality.
