Castelli 2014 Seamless Sleeveless Cycling Base Layer A13031

USE THIS FOR EVERY RIDE. With the polypropylene inner layer, nylon outer layer and open mesh construction, this base layer was created to work with our race jerseys to move moisture away from your skin as quickly as possible. It obviously works well in warm conditions, but we like it in colder conditions under a long sleeve base layer because this is the best way to keep dry and maintain body tem perature.
