Sport professionals demand nothing less than the best, and Oakley has answered their challenge for decades. World-class athletes have driven Oakley to create innovation after innovation, including interchangeable lens designs with unbeatable optical clarity. FLAK JACKET sunglasses take that to the next level with the latest in performance technology. The lenses in this polarized edition of FLAK JACKET are engineered to block the blinding rays of glare that are magnified by flat surfaces such as snow, water and pavement. Oakley uses a liquid infusion process to eliminate the haze and distortion found with ordinary polarized lenses. Optimized with Oakley polarization, FLAK JACKET offers the best optical performance on the planet.
