The Sanremo Speed Suit revolutionised the way pro riders dress when Castelli invented it back in 2011 but it is 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. CFD based seaming and wind-tunnel selected fabrics makes the suit aerodynamic, and it's comfortable thanks to the body fabrics that will keep you drier and cooler than other simpler Lycras. 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.
