Oakley O-Frame 2.0 Pro MX Goggles As an evolution of the legendary O Frame goggle, the O Frame 2.0 PRO family has Oakley DNA pumping through every vein. The O Frame 2.0 PRO MX extends the O Frame 2.0 PRO style and performance to a mid-sized fit, but there is nothing medium about it. The large lens with streamlined frame geometry expands the peripheral view in every direction. Flexible O Matter frame optimized for comfort, fit and maximized peripheral view. Triple-layer face foam fleece to wick away sweat. Includes an anti-fog treated high-impact resistant lens, plus a removable nose guard. Discreet frame notches at temples to provide compatibility with most prescription eyewear, without compromising fit.
