The M2 Frame XL OO9343-01 Polished Black Grey are the latest version of the M2 with a slightly taller lens design making them a great choice for activities like cycling. The curved lenses wrap around the face for side protection from the sun, wind and impact. They're super comfortable thanks to the lightweight O Matter frame, the three point fit and the unobtainium earsocks and nosepads that increase grip with perspiration so they will stay in place all day. Lenses are interchangeable to help maximise performance in any environment. Oakley Men's Wrap Polished Black Grey Sunglasses
