With relaxed style that draws on '60s surf culture, the Oakley Polarized TwoFace Sunglasses break new ground with a unique, multi-material frame construction. The combination of O Matter with an aluminum lower rim provides the durability you need for daily use while keeping weight to a minimum. Not to mention the glare-cutting and clarity-boosting Plutonite polarized lenses supply the high-end optics you've come to expect from Oakley.
