Enjoy more vertical eye coverage than Oakley's standard Flak Jacket sport eyewear.

Do you see shades of the Half Jacket XLJ in these Flak Jacket XLJs? At a glance the contoured Flak Jacket frame seems to be the only significant difference but the Flak Jacket XLJ represents a new generation of 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 XLJ 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. The XLJ lens design offers more vertical sweep or coverage than the standard Flak Jacket designs an essential feature for athletes with larger faces or those who tend to watch their foot placement more than others. Like the Oakley Half Jackets the Flak Jacket XLJ 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 Jacket XLJs giving you the slip before you reach the finish line.
