Taking the word literally, I suppose it would have to mean the canvas handbag I use when taking papers and perhaps an umbrella on a trip -- not enough to justify using my pack. The only things I keep in that bag are a few paper towels and a plastic bag in case I have to stow a wet umbrella.
However, I suspect that the idea is something like a fanny pack, that people take with them everywhere. The corresponding facility for me is two wallet-like objects that I bought at Eastern Mountain Sport & attach to my standard pants with rings thru the belt loops. The left one contains cash & serious cards (credit card, bank card, health insurance, etc.). The right one contains my datebook, address book (both printouts), membership cards, flashlight, Swiss Army knife, nail clipper, & (sentimentally hopeful) fuck kit. Attached to it is a cord with my keys on it.
