Pure speed.

The Sanremo Speed Suit revolutionized the way pro riders dress when Castelli invented it back in 2011. Other manufacturers have replicated the Sanremo front opening but no other speed suit is exactly as precise as the Sanremo.

While the front opening is the most visible part, Castelli has worked on every other detail to make this the perfect race suit. The CFD base seaming and wind-tunnel tested fabric make this suit exceptionally aerodynamic. Double V construction of the speed suit allows for greater overall support and comfort with the Progetto X2 Air Seamless Pad allowing you all-day comfort in the saddle.

The lower portion of the suit is the well-designed Free Aero Race 4 bibshort, the most comfortable suit for your longest, toughest race days. In addition to the new fabrics and seam placement, the two rear pockets with floating construction are even better for racing. The pockets are somewhat narrower for better aerodynamics but there are now 2 big pockets instead of 3 small ones, allowing for easier access when racing.
