Oakley expands on the Sutro franchise with the Sutro Lite. The half rim PRIZM shield expands your viewing area while boosting contrast to make details easier to pick up on. The Unobtainium saddle bridge increases with grip the more you sweat, making this sunglass great for physical activities such as cycling. There is additional Unobtainium grip with a textured pattern on the inside of the temple arms for maximum frame retention. Classic O Matter frame material compliments the comfort and durability of this sunglass. With the Oakley Sutro Lite you get coverage you need in a sunglass that is built to perform!
