Oakley Canteen Sunglasses rejects the gutless technology of ordinary eyewear. The Oakley Canteen glasses are far out of bounds when it comes to conventional eyewear. The Oakley Canteen Sunglasses utilizes High Definition Optics (HDO) for unbeatable performance, Plutonite lenses for 100% UV filtering, and patented XYZ OPTICS® for clarity at all angles of vision, comfortably lightweight from durable O matter frame materials, enhanced with dual cam hinges, and optimized with Unobtainium components that increase grip with perspiration. The Oakley Canteen Sunglasses are loaded with function and style.
