The Crave sunglasses feature a lightweight, flexible and durable grilamid frame, which makes it perfect for almost any athletic endeavor. The hydrophilic rubber stays grippy even when wet so the glasses will stick to your nose when you move, regardless of rain or transpiration. Lightweight, durable grilamid frame has a minimal, semi-open design supporting a larger field of view. Temples and the nose piece are both constructed from hydrophilic rubber and are fully adjustable for a secure fit that isn’t affected by strenuous activity. The durable PC lens from Carl Zeiss Vision offers outstanding optical performance and the open frame construction provides ventilation that helps to evacuate steam. Lens is ripel treated to help keeping fog, dirt and grime off your lenses and to makes water pearl off. Snap hinges can pop out in a fall, minimizing damage to the frame. Designed to match seamlessly with the Tectal and Tectal Race helmets.
