When Oakley says XL, they don’t play around. Using a standard-size frame, every millimeter of these enhanced Prizm lenses is optimized with High Definition Optics™ for a lightweight yet durable design. Prizm technology, beyond protecting from UV rays, enhances the wavelengths of certain colors to boost contrast and offer superior visual detail. The Lightweight O Matter™ frame features ellipse metal icon accents while Unobtainium™ earsocks and nosepads bring unrivaled comfort.
