Rain or shine, Oakley Flak Draft Alternate Fit sunglasses have your back. These semi-rimless O Matter frames are ultra-lightweight, yet extremely durable. Together with no-slip Unobtainium temple tips and nose pads, the Three-Point Fit aligns your shades by touching your head only at strategic spots. The Alternate Fit keeps these sunglasses in place over high cheekbones or a low nose bridge. Built-in ventilation keeps them from fogging up, so your vision stays clear even as the weather changes. If you need to change lenses, all it takes is engaging the single-release trigger. For shades that help you face the weather and triumph, try the Oakley Flak Draft performance sunglasses.
