Throw-N-Go Luggage
I wouldn't have it any other way. These are an inexpensive solution to rapid deployments and clutter reduction.
EBAY generic Bags
These are inexpensive and work fine. They are not built with the strength of an Army Backpack but they don't really need to be. The come with shoulder straps as well. Each liner has a double webbing handle that is sewn in to the side of the liner not a top seam, this is much stronger. Each bag has an inside zipper pouch to store your cell phone, wallet, keys and other valuables on one side, the other side has large inside divided pockets to keep your registration, maps and manuals in order (see photo below). We use 2 zipper pulls so you can open the liner from either end. Glove tabs are on each end so they can be easily opened with your gloves on. The zippered opening extends over the top and down both sides to make access to your items much easier. We finish of all interior seams with a binding and each is double sewn for long lasting durability. Ebay #39.95

Pretty much the same story, a good generic option for packing and trips.
