Castelli Sanremo 4.0 Speed Suit

The Sanremo Speed Suit revolutionized the way pro riders dress when Castelli invented it back in 2011 but they are still surprised that every other manufacturer has simply copied the Sanremo front opening rather than trying to come up with something original.

While the front opening is the most visible part, Castelli has worked on every other detail to make this the perfect race suit. It's aero thanks to CFD based seaming and wind-tunnel selected fabrics. It's comfortable thanks to the body fabrics that will keep you drier and cooler than the simple Lycra fabrics used by some other companies. The lower portion of the suit is created from Castelli's Free Aero Race 4 bibshort, to make the most comfortable suit for your longest, toughest race days.

Besides the new fabrics and seam placement Castelli also worked on the pockets to make them better for racing. They're somewhat narrower for better aerodynamics but there are now 2 big pockets instead of 3 small ones, so they're easier to access in racing.
