The Oakley Backhand is a gorgeous model for women. The fashionably oversized lenses give these sunglasses a glamorous 70s look and feel. The lenses are made of Plutonite®, and the frame is made of lightweight O Matter®. Both materials were developed in-house in the Oakley lab. The inside of the temple tips are coated with soft Unobtainium® pads for a secure and comfortable fit.
