As a direct evolution of the iconic OAKLEY O Frame® Goggle, the O Frame® 2.0 PRO is a purebred Oakley masterpiece. The O Frame® 2.0 PRO MTB offers an optimized style and improved performance compared to the O Frame® 2.0 PRO, designed specifically for a medium-sized fit but delivering far more than just mediocrity. The large lens and slim frame design expand peripheral vision in all directions. The flexible O Matter™ frame optimizes comfort and fit, guaranteeing maximum peripheral vision, while the triple-layer fleece foam on the front effectively wicks away sweat. The anti-fog lens ensures the highest impact protection and discreet frame notches allow most prescription glasses to be worn without affecting the fit.
