Sport professionals demand nothing less than the best, & we’ve answered their challenge for decades. World-class athletes have driven us to create innovation after innovation, including interchangeable lens designs with unbeatable optical clarity. FLAK JACKET XLJ has all the features & design of the FLAK JACKET, yet is made with a slightly bigger frame. FLAK JACKET sunglasses feature Oakley HYDROPHOBIC™, a permanent lens coating that prevents rain & sweat from building up on the lens. It also repels skin oils & other contaminates, so the lens is smudge resistant & easy to keep clean. It even eliminates static electricity, so dirt & dust particles won’t cling. FLAK JACKET lets you change lenses in seconds to optimize vision in any sport environment. Multiple lens colors are available, & 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 from UNOBTAINIUM® to increase grip with perspiration. FLAK JACKET is made from lightweight O MATTER® for all-day comfort. Pure PLUTONITE® lens material filters out 100% of all UV, plus the semi-rimless design means there’s no frame rim to block downward view.
