When the first generation Flak Jacket was introduced by Oakley it expanded, literally, on the popularity of the Half Jacket. With more lens coverage and the option of standard or XLJ lenses, the Flak Jacket was at home on the bike, while running, in the outfield, and just around town. In other words, it had serious crossover appeal as the Madison Ave folks like to say. The Flak Jacket 2.0 updates the popular model with even more lens area, with the taller semi-rimless lens design creating an expanded downward field of view that is 100% enhanced by Oakley's HDO® optics technology. The XL lens is a modified version of the cheekbone outlining XLJ, with less curvature and straighter outer edge. The Unobtanium™ ear socks are longer for more grip surface, despite the presence of moisture, and slightly larger nose pads from the same Oakley-developed material do the same.

The special Green Fade frame color is being offered to support Olympic athletes for the Rio games, and each frame has been hand-painted for the occasion, with a green and white scheme linked to Rio and the Olympics. With the addition of the outstanding PRIZM™ lens technology to the HDO® system, you also get the best optical clarity, glare reduction and color refinement of the environment throughout your viewing area through Oakley's proven Plutonite® material lens.

Oakley's time-tested durable and lightweight O Matter™ stress-resistant frame material is ideal for all-day comfort and protection required by active athletes. A principle concept behind Oakley's sport glasses is the Three-Point Fit system, which serves to use the ears and nose for frame contact without creating pressure points. To achieve this with the frame and lens design, proprietary Unobtainium® earsocks and nosepads increase grip with perspiration for a no slip grip.

Where Oakley truly has dominated sport eyewear is with their lens development. Plutonite® lenses are lightweight, yet are durable and optically pure- meaning the material and shape cause no distortion. Plutonite® has been engineered to filter out 100% of all UV rays, ensuring eye health. The lenses are also safety rated by the NSI for high mass and high impact protection, two tests that no one would ever volunteer for. Strength and safety are assured, allowing Oakley to focus on the most important aspect: optics. The company developed HDO® (High Definition Optics) to deliver the clearest, sharpest, most accurate vision without distortion or false magnification. This result is achieved through substantial testing and across the full field of the lens, at any curvature or shape.

PRIZM offers the most fine-tuned level of clarity and color distinction available in full or compromised light, such as shadow. The wearer can see texture changes and refined images that are crucial as a cyclist traveling on the road must constantly be aware of all changes and inconsistencies to make razor sharp judgments in handling, speed correction, and cornering. The level of refinement from the naked eye is impressive and immediate. The magenta-based PRIZM Field lens has a visible light transmission of 15%, increases contrast and responds to changing light conditions. It can handle high sun and full shade. The overall effect of the PRIZM Field is best seen through the eyes of a baseball player during a day game, with bright sun, blue skies, shadows, and green grass. The lens is darker than the PRIZM road lens and draws true distinctions among such a broad light and color range. Road and trail cyclists have gravitated for days or course where there is a considerable mix of canopy and bright light. While not developed for cycling, plenty of cyclists have PRIZM Field in their lens quiver.

Take the path to excellence with the excellent coverage, protection, and superior optical quality with the updated Flak Jacket 2.0 with the PRIZM Field lenses. Be bold and believe in the spirit of the Olympic Games while adhering to the same exacting dedication of the athletes that compete, and support them with the Green Fade frame design.
