Designed for fans of intense effort, such as vertical kilometre racing, thesesun glasses are uncompromising when it comes to performance and comfort. Their mono lens, available in photochromic Reactiv, guarantees a wide, obstacle-free field of vision, regardless of light levels. The suspended construction adds outstanding ventilation by encouraging air to pass between the lens and the frame. Last but not least, the Air Link concept and its shock absorber insert at the end of the temples offers even better grip and lightness.
