Oakley Flak Jacket Sunglasses

While the Oakley Flak Jacket might resemble the popular Half Jacket designs, there's more to the innovations than a redesigned frame. The Flak Jacket represents a new generation of Oakley sport eyewear performance. The interchangeable lenses have a permanent hydrophobic lens that repels skin oil, rain and sweat to optimize optical performance. The lenses also resist smudges and clean easier than previous eyewear, making the design better suited to endurance sports and extended climbing and backpacking. While some people found the Flak Jacket lenses easier to change than the Half Jackets, it's all really a matter of getting used to changing lenses. Like learning anything new, changing the lenses the first time around takes an extra moment or two. After that you can swap out lenses in a few moments and quickly adapt to new light conditions. Like the Oakley Half Jackets, the Flak Jacket has a featherweight O Matter frame with Unobtainium earsocks, and the proven three-point fit. Unobtainium tends to grip more when wet, so you don't have to worry about your Flak Jackets giving you the slip before you reach the finish line.
