Engineered to extend your angle of view in sport applications when your head is tilted downward, the XL rendition of Oakley's ultimate athletic design has the added benefit of optional straight stem geometry that optimizes the fit for helmet use. The Oakley Tour de France Radarlock XL Straight Glasses with +Red Iridium and G40 Vented Lenses exhibit durability and all-day comfort of the lightweight, stress-resistant O Matter frame material. You won't feel any uneven pressure points with this frame because its Three-Point Fit holds the frame comfortably in place while keeping the lens in precise optical alignment. Unobtainium earsocks and nosepads increase grip with perspiration. The high-profile lens provides glare reduction and tuned light transmission and is cut with 7mm of additional height above the nose bridge for an unobstructed view.
If you haven't heard about Oakley Switchlock Technology, you're wasting too much time fumbling with the outdated designs of ordinary interchangeable lens systems. This simple switch mechanism makes the process quick and easy, and the lens is held securely in place without uneven pressures that can bend it and distort your vision. Somebody finally got it right, and did so with a vengeance against conventional technology.
