Wind tunnel tested to show a 3-minute advantage on a 5-hour Ironman bike leg. We call it free speed. Well, almost...possibly the cheapest speed you can buy. Put this on after the swim and get to T2 three minutes faster than with the Free Tri Suit alone. You can gain even more if you put it over some of Castelli's competitors' pieces as tested in the wind tunnel. Get the bonus of sun protection and be ready to scorch the run.
