Castelli’s Free Tri Distance Suit is cut from their Hydrophobic Instadry Speed Fabric so you slip through the water and wind with minimal moisture absorption. It also sports their Velocity mesh back that's wind-tunnel tested for faster bike splits. Plus, Castelli's Kiss Tri chamois offers top comfort and support on the bike while remaining virtually unnoticed during the swim and run. You also get minimalist pockets so the suit remains hydro- and aerodynamic. This front-zip suit features no-sew under-arm construction to eliminate chafing, plus Castelli's Giro3 leg grippers to keep it comfortably in place.
