Oakley Flak 2.0 XL is an update from the original pair of wrap sunglasses, offering larger lenses and enhanced coverage. Oakley have implemented their patented High Definition Optics to deliver sharp vision and excellent clarity in all light conditions. The wrap frame, ideal for active sports, is made from lightweight O Matter that combines comfort and protection all-day long. Earpieces and nose pads are built from unobtanium to obtain grip, even when sweating or in rain. Mirrored lenses in matte black gives the sunglasses a contemporary finish and ensures full UV protection.
