Castelli Mens Seamless Sleeveless Baselayer

Seamless polypropylene/nylon to pull moisture off your skin 3 different mesh patterns to allow the most open mesh where you need the most ventilation Insanely soft for complete comfort. 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 moderate conditions, but we like it in colder conditions as well, under a long-sleeve base layer, because this is the best way to keep dry and maintain body temperature.
