Spot potholes and even subtler changes in the asphalt when you cycle with Oakley's M2 Frame XL Sunglasses. Fine-tuned for the road, Prizm technology enhances contrasts and color separation to build depth perception so you can identify bumps and curves faster. The M2's Plutonite lens filters out 100% UVA, UVB, and UVC rays, as well as blue light up to 400nm, and meets Oakley's High Definition Optics, which exceeds the American National Standards' ratings for optical clarity, visual, fidelity, and impact resistance. The lightweight, stress-resistant O Matter frame allows you switch the lens out, and there are Unobtainium temple and nose pads to ensure a good grip, even after you work up a sweat.
