Castelli Aero Nano

The Castelli Aero Nano are the aero overshoes for wet conditions. They sport the aerodynamics of a time trial overshoe, but also have water- and windtight fabrics and waterproof seams. During rain you keep water away from your feet, even the zipper is watertight. It won’t keep your feet warm in cold conditions though, as they don’t have insulation materials. Perfect for all rides, except the freezing ones.
