The Oakley Flak Jacket Sunglasses - Black Iridium Lens are for sport professionals who demand nothing less than the best. World-class athletes have driven Oakley to create innovation after innovation, including interchangeable lens designs with unbeatable optical clarity. Flak Jacket takes that to the next level with the latest in performance technology. Flak Jacket lets you change lenses in seconds to optimize vision in any sport environment. Multiple lens colours are available, and all lenses feature the unbeatable clarity of Oakley's High Definition Optics (HDO).
Choose the nose pads that give you the best fit - two sizes are included with every frame. Like the stem sleeves, they're made of Unobtainium to increase grip with perspiration. Oakley's Three-Point Fit optimizes comfort and holds the lenses in precise optical alignment for superior clarity. Flak Jacket is made of lightweight O Matter for all-day comfort. Pure Plutonite lens material filters out 100% of all UV, and Flak Jacket meets ANSI Z87.1 standards for impact protection. The semi-rimless design means there's no frame rim to block downward view. Optical clarity exceeds ANSI Z87.1 standards, and XYZ Optics extends razor-sharp vision all the way to the lens periphery.
