The Spy Optic Screw is built for the athlete who demands uncompromising performance from their eyewear. These sunglasses use Grilamid for an ultra-flexible, shatter resistant frame. The frame incorporates the patented Scoop technology which increases airflow to keep you cool in the heat and prevent lens fogging. The nose and temple pieces are covered with Hytrel rubber to increase the frames grip to the users face. The 7 base ARC lens allows the Screw to provide a high degree of wrap, so you can have the most optically correct, distortion free vision that is perfect for sporting situations. Matte Black frame with Grey lens. Frame measures 126-00-125. Includes a protective soft bag.
