Creating the thinnest wire frame was not enough for Oakley so they engineered a version with a metal so light it mocks gravity! Oakley used durable titanium to create an ultra-lightweight frame for all-day comfort. UNOBTAINIUM® was used on the earstems for a supple secure fit. As with all Oakley optics you get unbeatable performance from Oakleys HIGH DEFINITION OPTICS® (HDO®) which provides stunning clarity, HDO® allows Oakley to contour the lenses for a peripheral view that is wide and crystal clear. The pure PLUTONITE® lenses filter out 100% of all UV and provide impact protection to meet all ANSI Z80.3 standards
