Whether you're grinding up the mountain on your bicycle or prowling off the coast in your kayak take it all in with the wider view of Oakley's innovative dual-lens Half Jacket. It features interchangeable lenses found on other Half Jackets so you can adapt to the intensity of changing light conditions but the frame design gives you a wider field of vision and enhanced protection. The open-edge design helps extend your vertical field of vision while protecting your eyes from harmful UV rays. Unobtainium® earsocks and grip anchors keep the frame from sliding around on your face.
