Free Speed, Free Comfort, Freedom.

Setting out to make your next triathlon easier and more comfortable, Castelli's Free Tri Short combines a great anatomic fit with quick-dry technical fabrics. With its Hydrophobic Speed fabric, the Free Tri Short is fast in the swim with minimal water absorption, and quick-to-dry for a comfortable ride and run.

Inside this triathlon short, the Kiss Tri seat pad offers just what you need for the ride, while disappearing on the run. With its SnapLock fastener located at the lower back, the shorts clip to compatible jerseys to prevent riding up or falling down during the swim or bike leg. Flatlock stitching and a drawcord waist keep you comfortable by minimizing any zippers or seams that can cause irritation while on the move.

Elevate your adventures with the Castelli Men's Free Tri Short. High-quality Giro Air gripper elastic along the leg keeps these shorts in place, so you don't have to struggle with continually readjusting. Complete with two small pockets on the hip that can hold your keys or nutrition, you're set to enjoy the day with the things you love most.
