New chassis geometry. Same cool factor. Tralyx Slim allows athletes and weekend warriors with narrower faces to benefit from the superior comfort and lightweight of our iconic performance machine, the Tralyx. Tralyx Slim is designed to maximize the fit for women, narrower faces, Asian conformations as well as younger athletes. The new shape incorporates the same features of the Tralyx: shield lens for uninterrupted field of vision, Power Flow ventilation System, Adaptive Tips and a co-injected Ergonose IX. Tralyx Slim mounts ImpactX unbreakable photochromic optics and the vibrant RP Optics Multilaser lenses to ensure maximum eye protection and face any light condition.
