Speed on the bike and in the water. The Castelli Free Tri ITU Suit has SpeedFreak ventilated race fabric on the front of the upper is both breathable and matches perfectly to the aerodynamically efficient VeloCity rear mesh. The Instadry Speed fabric on the short offers minimal absorption of water, so swimming speed isn’t impeded upon.
A 30cm long YKK® camlock zipper is placed at the rear to keep it out the way and the soft-finish armholes reduce chaffing, while the FreeAero 2 hydro and aero optimised pockets offer convenient and efficient storage. The KISS Tri seat pad is ideal for hard charging on the bike, but isn’t intrusive when swimming and running. This triathlon suit is compliant to ITU rules.
