The seasons never slow you down, and your kit shouldn't either. That's why Castelli designed the Core Seamless Short-Sleeve Base Layer to keep you warm and dry all year long. The reimagined fabric blend repels moisture so you won't feel like a wet sponge, and the seamless construction has our Gearheads pedaling in superior comfort.
