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®.
• The side curvature of the 8.75 base lenses extends your peripheral view while providing coverage that improves side protection against sun, wind and impact
• Unobtainium®: A soft hydrophilic synthetic, it increases adhesion when wet to grip better when you perspire. This makes it ideal for earsocks and nose pads in performance eyewear
• High Definition Optics® (HDO®) is a collection of patented technologies that allow Oakley eyewear to meet or exceed the testing standards of the American National Standards Institute for optical clarity, visual fidelity, and impact resistance
• Prizm™ Trail Lenses: A revolutionary lens technology that fine-tunes vision for specific sports and environments. Prizm Trail lenses allow you to easily distinguish obstacles such as rocks, sand and hard packed dirt so you can ride with confidence
