Oakley’s Prizm Road Racing Jackets have revolutionary lens technology to help you perform even better out on the road. Oakley’s Prizm lenses are optimized for the color and light transmission experienced on the road, so you get unbeatable clarity to see subtle changes in the road surface. Of course, they also block 100% of UV rays and meet the highest impact protection standards. But that’s just the start. The innovative frame design employs Oakley’s incredibly lightweight and strong O-Matter material, which delivers a premium fit with outstanding performance. Featuring Switchlock technology, the lower part of the frame opens for simple lens changes (extra lenses sold separately). The lenses are held in place with a suspension system so stresses on the frame won’t distort the optics, providing you with perfect visual clarity. The ear and nose pieces are made of Oakley's Unobtainium, which increases its grip when it’s wet, so your glasses stay exactly where you want them.
