Nope. Well actually I do, just haven't used it in a few years, some thin brown leather thing.
I keep all my ID and card related paraphernalia within my jackets breast pocket. $40 goes in a custom made interior sleeve pocket (Holds the cash in place, just reach in and grab what I need) any extra money goes in the interior hidden breast pocket, small bills go into the interior pocket within the front right pocket. Receipts are kept within the interior pocket within the front right pocket. Large change goes in the right front pocket, small into the left. BusPass is clipped into place within the left sleeve for easy access. Pictures of loved ones go in the breast pocket. Any misc items distributed depending on necessity and ease of access.
This jacket has so many pockets and recesses and holding clips, even before I added a ton more, that I've never had want of a wallet or backpack. Still need to add more holding straps on the right interior... and a few belts so it can't be stolen off my back without some serious effort.
I currently have $40 in the sleeve, $220 in the interior breast, $14 in the front right, and $3.68 in the left. I'm my own damn bank.
