The Oakley Sutro Prizm Black is a new pair of cycling glasses designed with performance in mind. It gives the wearer a bold and versatile look, and is very useful both on and off the bike. The Oakley Sutro Prizm Black offers good protection against the elements, which is mainly due to the Prizm Black lens technology. The lens has a light transmittance of only 11%, which significantly improves your vision in bright light conditions. In addition, the frame of these cycling glasses is relatively large to protect a large part of your face. Thanks to the Unobtainium nosepads, the glasses are comfortable to wear and remain firmly in place. The Oakley Sutro is equipped with the Prizm Black Lens whose 11% light transmittance is ideal for cyclists who ride mainly in sunny conditions. In such conditions, the lens makes dull colours warmer, enhancing contrasts. Also, the black lens is less conspicuous than Oakley's other multicoloured lenses.
