Three decades of Oakley innovation have changed sunglasses from a generic accessory to vital equipment, and all that evolution has led to a single inevitable outcome: the best performance eyewear on earth. This is it, and you can thank the world's greatest athletes and their relentless pursuit of perfection because that's what drove Oakley to defy the limits of what is possible. Whether you're competing for Gold or just squeezing every ounce of possibility out of those prized moments of athletic escape, you're either wearing RadarLock or wishing you were. 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. RadarLock XL offers a full 19mm height at the nose bridge so your head can stay tucked in activities like cycling, and it comes with all the premium features including Switchlock Technology that lets you adapt your vision quickly and easily by taking advantage of Oakley's wide array of interchangeable lenses. You'll also have unbeatable comfort, along with the unrivalled clarity and protection of High Definition Optics (HDO) for taking performance beyond the limits of reason.
If you haven't heard about Oakley Switchlock Technology, you're wasting too much time fumbling with the outdated designs of ordinary interchangeable lens systems. Oakley's 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. HDO sets the standard for optical clarity, visual fidelity and impact resistance, and RadarLock XL is racked and revved with all those benefits including Polaric Ellipsoid geometry to extend clarity across the entire lens. The sweeping contour gives you a wide-open view with maximized peripheral vision and enhanced side protection against sun, wind and impact. You'll have optical performance rated at ANSI Z87.1, and that same uncompromising level of standards applies to protection against high velocity and high mass impact. For even more protection, Oakley Plutonite lens material filters out every eye-searing ray of UV. The lightweight yet insanely durable frame is made of O Matter and shaped with surge ports to maintain a cooling flow of air. Interchangeable nose pads let you achieve a comfortable, customizable fit, and the ear socks are made of the same sport-optimized Unobtainium to increase grip when you sweat. 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.
