Wouldn't this defeat the purpose of the sweat wicking properties of the jersey? You don't want to keep the moisture of sweat to remain close to your body, but to be wicked away by the polyproplene properties of the jersey.Originally posted by Guest
Always wear a T-shirt under your cycling jersey. This will provide some protection to shoulders etc. in the case of a fall. Also helps absorb sweat which will feel better than a soaked jersey.
