Oakley's Radar EVs were developed with input from the world's top pro cyclists, so they'll be perfect for you, too. The frames use Oakley's lightweight O-Matter material, and their unique geometry provides a refreshing flow of air to keep you comfortable. The EV designation means the lens is taller in front of your eyes for uninhibited vision, even in the most aero position. The Plutonite lens filters 100% of all UV rays and meets the highest impact protection standards. The ear and nose pieces are made of Oakley's Unobtainium to keep your glasses exactly where you want them, and two nose pieces are included with every frame for a perfect fit.
