Oakley Half Jacket 2.0 Sunglasses. The original Half Jacket became essential gear for athletes, and version 2.0 takes the proud heritage to the next level of design. But when it came to protection and comfort, Oakley were not about to mess with the best, so they made it with the same lightweight O Matter frame material and Unobtainium components that keep it comfortably in place, even when you are dripping with sweat. The Three-Point Fit wont hook your ears like ordinary frames, and it keeps the lenses in precise alignment so they can give your eyes the vision of victory. This premium eyewear meets ANSI Z87.1 standards for optical clarity and impact resistance. Polished black frame with black iridium coated lenses.
