Our clothing sizing is made to European cycling standards. This means that they fit very tight for performance cycling. If you don't want it to be skin tight, please order one or even two sizes larger than your normal size. It's also a good idea to go up by two sizes in the long sleeve jersey so it can be worn over other clothing. The rain jackets fit even tighter, so please go up by two or three sizes from your normal clothing size. We do accept returns and exchanges, but you can avoid this by sizing up. Email us with any questions you have.
