Base Layers

The Castelli Core Seamless Base Layer is designed with a seamless construction to enhance comfort, reducing chafing and irritation during wear. Featuring advanced moisture-wicking properties, this base layer ensures you remain dry and comfortable.

It’s crucial that our upper body gets an added boost against the elements during those cold fall and early spring conditions. As a solution, we developed the Spring/Fall LS Skin Layer, which has taken the torch from our iconic Skinfoil base layers.

Eliminate unwanted bulk underneath an aero race jersey with the ASSOS 1/3 Sleeveless Skin Layer P1, a sleeveless baselayer built with a second-skin fit to keep us cool during a hot summer ride.

To sleeve or not to sleeve—that is the question. Sure, it all boils down to a matter of preference, but the objective remains the same for any cycling base layer: increase comfort and maintain a consistent body temperature.
