Yeah, it might feel funny to have that diapery-feeling pad under you when pulling on cycling shorts. But that pad—or chamois—serves a purpose. Aside from padding, it’s made of special microfibers that not only move with the skin but move smoothly against the skin, preventing chafing. The cotton of your tighty whities may seem fine, but cotton actually abrades the skin. Not good. A basic cycle short for training will make your bike-riding experience much more enjoyable.
