The original Oakley Half Jacket became essential gear for athletes, and version 2.0 takes the proud heritage to the next level of design. When it comes to protection and comfort, Oakley gives you the best. Made with the same lightweight O Matter frame material and Unobtainium components that keep it comfortably in place, even when you're dripping with sweat. The Three-Point Fit won't hook your ears like ordinary frames, and it keeps the lenses in precise alignment so they can give your eyes the vision of victory. Pure Plutonite lens material filters out 100% of all UV, and meets ANSI Z87.1 standards for impact protection.
