The Oakley Gas Can polarized sunglasses are built to stare down the most rugged trails with confidence. Tough, lightweight O Matter frames will take the abuse of rough days on the track without flinching. Optically correct XYZ lenses ensure you'll stay focused on your opponents. Polarization reduces the glare of asphalt and water, so you don't miss a moment of the action. The Gas Can exceeds ANSI standards for impact resistance, and the Plutonite lenses block all the harmful UV rays that could slow you down.
