Castelli updates their distance triathlon suit with new fabrics and refined fit. The Free Sanremo 2 Suit capitalizes on research that went into its predecessor as well as the Castelli PR Suit to bring you aerodynamic advantage and a fit that feels comfortable through each leg. A snug fit layers well beneath a wetsuit and the quick-drying fabric helps you speed through each transition. On the bike its flatlock seams and tri-specific chamois minimize chafing and friction for a comfortable stride.
