When you’re carving through high-speed corners on your road bike, you need crystal clear vision to choose your entry and exit points. Oakley’ Prizm Road Flak Jacket XLJ has you covered with the revolutionary Prizm Road lenses, which are optimized for colors and light transmission experienced on the road. The result is unbeatable optical clarity to see changes in the road surface and less eye fatigue at the end of the ride. The Prizm lenses are just the beginning though. The frames use Oakley's lightweight O-Matter material and feature a semi-rimless design for an extensive field of view. The Plutonite lenses filter 100% of all UV rays, meet the highest impact protection standards and the XLJ designation means the lenses offer more coverage for larger faces. Plus, 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.
