Light, stretchy, and moisture-wicking, the Castelli Men's Active
Cooling Sleeveless Base Layer effortlessly layers under your
favorite jersey to regulate your core temperature on sweltering
summer rides. Its Prosecco Ice fabric moves sweat off your body
to facilitate evaporative cooling. This fabric also shields your
upper body from harmful UV rays, as backed by its UPF 50+ rating.
Another cool feature is dynamic graphics, which disappear along
areas of heat dispersion.
