If you’re wearing Oakley sunglasses, you’ve got technologies that set the industry benchmark and beat all optical tests of the American National Standard Institute. The patented innovations of Oakley’s HIGH DEFINITION OPTICS® (HDO®) can’t do their job if your lenses are dirty, dusty or coated with a fog of skin oils. The HDO® Lens Cleaning Cloth is a 12"x12" lens cleaning cloth that is composed of a lens-friendly microfiber synthetic called MICROCLEAR™. It makes cleaning easy, and it should be part of your standard gear because the precision of Oakley HDO® deserves nothing less than the best.
