I have a pair of canvas fuel cells. I just didn't like these as much as I thought I would. I am looking to trade for a pair of Jawbones / Racing Jackets, other Fuel Cells, and switch style. You will get the glasses and the special microfiber bag. The frames are in very good shape but the arms are a little loose. The lenses do have some marks in them I would say they are a 8 out of 10. You can not see them when looking through them as you can see by the pictures. Also I know these had grey in them brand new but i am unable to tell if they are still grey or if they are Black Iridium. Any help on that by pictures would be great. I have compared them to other Black Iridium lenses I have and they are very close but I do not have any grey for comparison. The only other thing I can add is you can not see your eyes when wearing them.
