I started buying Oakley's a few moths ago and I honestly had not heard of x-metals till I joined the forum. Finally I decided to get me a x-metal. After doing a little research and asking @kronin323 some questions I went ahead and picked this pair up. Carbon frame/Ruby lenses. The lenses have some scratches but the frames are in great condition. I will be sending them out to @THE X-MAN for some work when I decide on what new lens I am going with.
