Oakley - SI Flak Jacket

Flak Jacket™ is made of lightweight O MATTER® for all-day comfort. Pure PLUTONITE® lens material filters out 100% of all UV, and FLAK JACKET™ meets ANSI Z87.1 standards for impact protection. The semi-rimless design means there's no frame rim to block downward view. Optical clarity exceeds all ANSI Z87.1 standards and XYZ OPTICS® extends razor-sharp vision all the way to the lens periphery.
