I use a small backpack in the Parks. It has a couple of small pouches as well as the main pouch. Each one has a zipper. I attach one large diaper pin to all three zippers. It's impossible to slide any one open when they are all pinned together & diaper pins are made to be difficult to open anyway. No one is likely to get into the bag without a lot of tugging & frustration.
