Castelli combined two of its most popular products to create the Sanremo 3. 0 Speed Suit. Up top is Catelli's Aero Race 5. 0, with dimpled 3D fabric similar to a golf ball meant to slice through the wind and get you down the road faster. The bottom half is a bib free version of Castelli's Body Paint shorts, also with surface dimples and made of a single piece of supportive fabric for a seamless, irritation free fit. At the core of this speed suit is the Progetto X2 Air Seat Pad, an antimicrobial chamois with seamless construction, four way stretch, and a perforated foam layer for a soft, ventilated, friction free ride. Paying attention to even the little details, Castelli rounds out the Sanremo 3. 0 Speed Suit with Giro 3 integrated leg grippers. These bands eliminate the need for pinchy elastic and provide a smooth and gently compressive surface to hold everything comfortably in place.
