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.
