Oakley Double Edge sunglasses are a part of Oakleys Active performance collection, constructed with features that play a significant role in this collection. This pair of Oakley sunglasses feature a frame made up of Oakleys proprietary O Matter material, creating a lighter, more durable pair of sunglasses. The Double Edge frame has a large rectangular lens designed for people with medium to large faces and it's compatible with hats. Oakleys Three-Point Fit system allows the Double Edge to comfortably fit your face and the Unobtanium nose pads create a tighter grip to maintain a secure grip.
