The Castelli Chill Sleeves actually cool you down as you sweat in the heat. The Prosecco Ice fabric is technologically designed to activate as your body heats up. When you sweat, the fabric spreads the moisture throughout so it can quickly evaporate. Air circulates through the fabric to add one more cooling quality to the cycling arm sleeves. The exceptional elasticity gives these arm sleeves a second skin feel so they stay in place no matter how much you move around on your bicycle.
