As an evolution of the legendary OAKLEY O Frame® Goggle, the O Frame® 2.0 PRO is a thoroughbred Oakley product. The O Frame® 2.0 PRO MTB offers an optimized style and enhanced performance with a medium-sized fit. It is far from average. The large lens and sleek frame design expand peripheral vision in all directions. The flexible O Matter™ frame optimizes comfort and fit while ensuring maximum peripheral vision. Additionally, the triple-layer fleece foam in the front area efficiently wicks away sweat. The anti-fog lens provides the highest impact protection and subtle frame notches allow for most prescription glasses to be worn without compromising on fit.
