Fast Legs Sleeves

The Castelli Fast Legs Sleeves are calf aero sleeves made for road cycling and race-day use, wind-tunnel tested to reduce drag and optimized within Castelli’s Rosso Corsa racing line.

They’re made from an 82% polyester / 18% elastane compression fabric and feature internal silicone tape at the top to help keep the sleeves from sliding.

The sleeves come in international sizes XS–XL, with lengths ranging about 62–70 cm and circumference measurements around 29–39 cm depending on size.

They’re intended for spring/autumn and warm-weather road cycling, especially when you want aerodynamic benefit on race or fast-ride days.
