Oakley make eyewear good enough for people who commute at three times the speed of sound. So it’s only natural that Oakley sculptured a frame with aviator styling. C-5™ alloy keeps it lightweight and comfortable, and supple UNOBTAINIUM® components increase grip with perspiration. It also offers 100% UV filtering and impact resistance that meets all ANSI Z80.3 standards. But the best thing about CROSSHAIR™ is something pilots insist on, along with everybody else who takes their vision seriously: the unbeatable clarity of Oakley’s HIGH DEFINITION OPTICS® (HDO®).
