Tailored with a polypropylene inner surface, nylon outer surface and open mesh construction, the Castelli Seamless base layer was designed to move moisture away from your skin as quickly as possible. It obviously works extremely well in warm conditions under any short sleeve jersey, but Castelli also suggests you try it in colder conditions under a long-sleeve base layer. This is a great way to keep dry and maintain body temperature.
