Following the popularity of the Mainlink, Oakley engineers introduced a larger version with all the same great features. Unobtanium grip along the bottom of the temples and nosepad make this sunglass extremely versatile. Although it does not look like a typical sport frame, the Mainlink XL is fully capable of meeting any sport-driven demands. O Matter frame construction makes these frames lightweight and durable so you can use them for virtually any activity. This sunglass is available with Oakley Authentic Prescription lenses.
