got these yesterday all i know about them is they were given away or won at a golf tournament in atlanta, they are fuel cell with the golf ball logo (which ive only seen on hijinx) great looking glasses not sure what the lens is it is not warm grey or black iridium, vr28 maybe not sure they also have THE ATL '10 on the left lens. also the bag needed a good washing. i have a plan for them just ordered some matte black tonals and some black iridium lenses from si and im gonna swap icons and wear the heck out of them. so are these "grab bag"? ive heard the term but not sure what it means or if these are the type.
