This rare edition of SPIKE utilizes a virtually indestructible metal that is so lightweight, the defense industry reserves it for fighter jets. A leightweight frame that offers all day comfort is just part of the story. Oakley added HIGH DEFINITION OPTICS® (HDO®) for unbeatable clarity and pure PLUTONITE® lenses to optimize protection against impact and UV. This combined with supple UNOBTAINIUM® components to increase grip with perspiration creates an authentic style means going against the standard. That includes the standard idea that you have to sacrifice performance just to look good.
