Radar is made of lightweight O Matter® for all-day comfort. To keep the heat of competition from swamping you with sweat, the frame geometry creates a cooling flow of air. Pure Plutonite® lens material filters out 100% of all UV, and Radar® meets ANSI Z87.1 standards for impact protection. The semi-rimless design means there's no frame rim to block downward view. Optical clarity exceeds ANSI Z87.1 standards, and patented Polaric EllipsoidTM geometry extends razor-sharp vision all the way to the lens periphery.
