Oakley Gas Can S Sunglasses- The Oakley Gas Can S Sunglasses prove that Oakley pumped the dimensions of their original Gas Can with the pulse of the street, fueling a one-of-a-kind. Now the aggressive design language called Oakley SQUARE O brings a new urban contender. Oakley Gas Can S turns down the volume of O MATTER® frame material, reducing the overall size with some harder lines that make it streetwise. Metal icons tag it as true Oakley. HIGH DEFINITION OPTICS® (HDO®) keeps visual performance at full tilt, and impact protection meets all ANSI Z87.1 standards.
