Made for optimal comfort in the heat, the Free Sanremo 3 Sleeveless Suit has been engineered using CFD-based fabric placement and seam construction plus wind tunnel tested stretch fabric on the legs, for improved aerodynamics, while soft fabric overlap around the armhole boosts its wearability.

Cooling, important for the determined competitor, is delivered by the incorporation of an internal neck pocket made to hold ice, light fabric throughout and the suit's namesake Sanremo front opening. The latter makes it easier to bend while cycling and straighten out during the run and swim. It also allows for easy calls of nature, while the zip fully opens for added ventilation.

Built around a minimalist, fast-drying seat pad that you'll forget about during your run, the suit also features pockets that lie flat, for better hydrodynamics during the swim and safe carriage of nutrition at any point.

All of these features add up to a suit uniquely fitted for triathlon, which bears Castelli's Rosso Corsa label, a hallmark of true racing pedigree.
