Castelli Women's Free Tri ITU Suit

Castelli have expertly built the supportive and versatile Women’s Free Tri ITU Suit while still making it compliant with ITU rules, which means it’s perfect for future Ironman champions all the way down to plucky novices. This suit, the female-specific version of what Fred Van Lierde wore when winning the 2013 Ironman World Championships, is made with the legendary KISS Tri seat pad within its chamois (made with an antibacterial top layer that keeps you feeling fresh and padding in all the right spots), which disappears with ease when you move into the run section.

But the superb seat pad is not the end of the story here, and the Free Tri ITU Suit is ideal for improved performance in all three stages of a triathlon. SpeedFreak fabric on the top half is ventilated for coolness as you run and ride, while also helping the wind work for you to improve aerodynamics, while the outside of the shorts feature Instadry Speed fabric that avoids absorbing water when you swim. On top of that, a pair of pockets on the hips keep nutrition within quick and easy reach, GIRO Air leg grippers keep everything perfectly in place, and soft-finish armholes help to reduce chafing.
