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.
Integrated Technologies
8 Base Lens
The side curvature of our 8.75 base lenses extends your peripheral view while giving 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®
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™ Road
A revolutionary lens technology that fine-tunes vision for specific sports and environments. Prizm Road lenses enhance the road so you can see obstacles like rocks and potholes quickly and feel more confident as you ride.
