Thoroughly Engineered for race day Performance
Meticulous preparation goes into your race day, and possibly even more into Castelli’s Free Tri products. Free is fast thanks to the water-repellent fabrics that are also wind tunnel tested for on-bike speed. And Free helps you perform at your maximum by providing just right muscle support and keeping your body cool. Details are carefully thought out, like the Free aerodynamic yet high capacity pockets, Speed Hooks that can secure your jersey and prevent it from riding up during the swim and bike. Even the back fabrics shows the engineering in this garment: wind tunnel tested for on-bike speed, it also provides exceptional cooling while offering UPF 16 protection. That means that 94% of UV rays are blocked, providing a reasonable level of protection, but it can be combined with sunscreen for those with sensitive skin. We think it achieves a good balance between protection, cooling and outright speed.
