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 MTB 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 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.
