One of the most popular models in Oakley's lifestyle line, the Oakley Gascan Sunglasses are so unique Oakley had to customize their logo just for these shades. Each Gascan frame is made with lightweight, stress resistant O Matter material and features an extended wrapped geometry for medium to large faces. The lenses on the Gascan are cut from the same toric shield for better lens geometry, increasing the clarity and the field of view. Each set of lenses are made from Plutonite material that is designed to block 100% of UVA/UVB/UVC and harmful blue light. Also if you are worried about durability the Oakley Gascan's exceed impact durability standards.
