The most incredible feature of the Oakley Flak Jacket sunglasses is their interchangeable lenses with unbeatable, high definition optical clarity. You can optimize your view in any environment—desert, jungle, urban, rural or any climate where sun protection is the name of the game.
Nose pads come in two sizes, and like Oakley’s stem sleeves, they’re made of Unobtainium, which increases grip even with perspiration. Oakley’s three-point fit also positions the lenses optimally for superior clarity and optical alignment.
Like many of their designs, the Oakley Flak Jacket sunglasses are made of lightweight, O Matter material plus Plutonite lenses that filter 100% of harmful UV rays. These sunglasses also meet ANSI Z87.1 standards for impact protection. For fast maneuvers, you need to be able to move your head around on a dime and see in all directions quickly; the semi-rimless design of the Flak Jacket has no annoying rim to block your downward view. In terms of optical clarity, this model exceeds ANSI Z87.1 standards and the XYZ Optics extend razor-sharp peripheral vision.
