Description
Developed and fine-tuned in collaboration with some of the worlds fastest athletes, the Castelli Sanremo 4.1 Short Sleeve Speed Suit is the culmination of over 10 years of World Tour and road testing. Engineered for aerodynamic performance, this suit utilises a range of Castelli technologies to cut through the air and reduce wind resistance.
Dimpled Vortex fabrics are used on the legs to deliver muscle support and aero benefits, while the inner leg sees Forza stretch fabrics for an effortless fit. GIRO4 leg gripper elastic ensures the short stays put, while Castelli’s unique Doppio V construction ensures support and comfort from the short.
Highly breathable, the Velocity Rev2 fabrics on the front and sleeve provide unmatched airflow to keep you cool and dry throughout your ride. Airflow shoulder construction further reduces wind resistance, and elbow-length raw-cut sleeves ensure a smooth transition between the garment and your skin.
