Zerod tri-suits are already worn by many professionals, why don’t you try it as well? Their oSuit is designed for shorter distances like Sprint and Olympics and to give you the edge on your competition. It’s made of W3 (Water Wear Weapon) woven fabric made in France to provide compression with greater durability and increased muscle support. Feel comfortable with its flat seams plus smooth stitching along with the flexibility of the material. A water-repellent fluoro treatment combined with its light weight means W3 dries in just five minutes.
