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. Features Anti-fog and high-impact lens. HD Optics technology eliminates distortions and ensures a clear, sharp vision. O Matter frame, optimised for comfort, fit and maximum peripheral field of vision. Three-layer foam with fleece outer fabric for better moisture management and a secure fit. Discreet notches in the frame at the temples offer compatibility with most prescription glasses without compromising on the fit. Adjustable strap with non-slip silicone.
