With an aggressive design and innovative materials, the Oakley SI Turbine delivers non-stop comfort and visual performance. The stress-resistant O-Matter frame features Unobtainium nose pieces and earsocks, which holds the glasses in place at all times, even when wet. These glasses are made with Oakley's patented Three-Point Fit, ensuring the frame only makes contact with the sides of the head and bridge of the nose. This eliminates pressure points commonly found in frames that hook the ears. Plutonite polycarbonate lenses offer total protection from harmful UV rays and are treated with scratch-resistant and Fogproof coatings for uncompromised vision. These durable glasses look great and perform at a high level in any setting.
