Developed and perfected for six years on the World Tour, the Castelli Sanremo 3.2 Speed Suit is the fastest, most comfortable, road-racing suit on the market. Updated with faster drying fabric on the front and a new lower portion, the Sanremo 3.2 will change the way you ride. The upper is constructed based on the Castelli Aero Race 5.1 Jersey and features a 98 percent polyester fabric to keep you dry, plus a surface texture, so it even faster in the Wind Tunnel. The lower portion is Castelli's Free Aero Race Shorts, which delivers maximum comfort, muscle support and aerodynamics. Progetto X2 Air chamois provides the ideal blend of support, ventilation and quick-drying performance for race-day comfort. Open front makes it easy to put on, easy to ventilate and convenient for nature brakes. Three back pockets with limited stretch stay in perfect position, even when fully loaded.
