Proving its worth in the wind tunnel when pushed to the limit, the Castelli Free Speed Race Jersey is constructed from two types of ventilated fabric (Velocity Mesh in the back and SpeedFreak over the front) to not only reduce drag from the air but also keep things highly breathable when you most need it. It’s a highly efficient jersey too, and works beautifully when pairs with the Castelli Free Tri Shorts thanks to the SnapLock fastener at the waist. Thanks to the practicality of the Free Speed Race Jersey, it’s a highly versatile bit of apparel that you can use in all three stages of triathlon. The back features added storage in the shape of aero optimised pockets and two hydro options that are ideal for looking after nutritional items. Extra elastic in the shoulder adds extra comfort to the swim and run sections, and the YKK Camlock Zipper makes it dead easy to get in and out of in a hurry. Highly breathable to enhance your experience at every stage, this Castelli jersey will change your triathlon for good.
