Our 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, we weren’t about to mess with the best, so we made it 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.
