Real deal Oakley Gascans NON polarized. Matte black with silver O with no scratches on the lenses and they come with Oakley bag. They go for $90 new. $50 and they are yours.
UpdateI have a spare set of brand new polarized lenses for them if your're interested for $40 more. If you want both the lenses and glasses then $90 total.
In this third pic you can see the O on the back side by the ear.
