The pro peloton demands nothing less than the best, and the Oakley Flak Jacket has answered their challenge for years. Oakley's High Definition Optics offers unbeatable clarity at all angles of vision, while open-edge frame design enhances downward view. Innovative Hydrophobic™ permanent lens coating prevents rain, sweat or splashing runoff from leaving streaks and sheens that compromise vision. It also repels skin oils and other contaminates, so lenses are smudge resistant and easy to keep clean. Includes multiple interchangeable nose pad options for customizable and comfortable secure fit, made from Patented Unobtainium, which actually increase their grip as you perspire. Jet black frame with Black Iridium lenses.
