So today i chex out this oakley tent at grouse when im done skiing. and this guy brings us into this van were they do lens testing. He then goes on about how oakley kicks ass and beats ever other optics company out there. He then puts one of oakley's competitors glass on a dummy head and puts a metal ball into a machine which shoots the lens. Its pretty much a pelit gun. The ball just totally destoryed the glasses but when he did it to some oakley glasses notin. He did another test and droped a metal spike on another pair of oakley competitiors glasses and same result for the competitors glasses and oakleys. He also should us oakley glasses that have been shot with shotguns that did not break. So i suggest you get some oakleys because i no I'am. You just never no when a metal ball or big metal spike will come flying at your eye.
