Bottom zipper functions., everything functions and the loft is great. The top zipper actually open very easily compared to my other bags.....it would be good for a person who may have bag anxiety.....price is firm, if it does not sell I will just keep it/use it. PM questions, great older bag in very functional condition....if I had not gotten used to a longer bag in recent years I would be using it. Check my feedback and Merry Christmas to everyone
