Oakley SI Flak 2.0 XL Matte Black w/ Prizm Grey Polarized Lenses #OO9188-85

The XL edition offers a standard size frame with enhanced lens coverage, and every millimeter of the peripheral view is optimized with High Definition Optics in a durable yet lightweight design that takes performance to the next level and brings style along for the ride. Essential gear for competition, Flak 2.0 XL has 8.75 base lens curvature for protection against sun, wind and impact, and patented XYZ Optics maintains clarity along the full curve while you push your limits with the comfort and secure grip of Unobtainium. We created an array of lens/frame combinations so you can choose options including the glare-cutting power of HDPolarized optics, the balanced light transmission of Iridium lens coatings, and Prizm lens technology that fine-tunes vision by emphasizing colors where the eye is most sensitive to detail.
