Castelli's hydrophobic fabric is fast in the swim, but doesn't take on any water. Wind tunnel-tested mesh covers your back, minimizing drag to increase your speed on the ride and run. Micro clip hooks lock your top onto the Donna Tri Shorts for a race suit-like fit, and seamless underarm construction lies flat against your skin, eliminating rubbing and distractions.

Castelli’s race heritage shines through the Free Tri Collection, taking the design innovations from their cycling kit and incorporating speed-enhancing features like hydrophobic fabric and velocity mesh. The collection is an accessible, technical race assortment for those looking to move fast, race in comfort, and greatly diminish transition times.
