Face the day in style with Oakley Holbrook Mix sunglasses. The combination of O Matter and stainless steel creates lightweight, durable frames that hold their shape and meet ANSI Z80.3 standards for impact. Unobtainium ear socks increase their grip to handle perspiration and other moisture, so these shades stay put. These Oakley O Matter sunglasses feature a keyhole bridge that balances the stainless steel frames on the sides of the nose for added comfort. The square profile flatters the features of oval and round faces, and the size suits medium and large faces.
