I purchased this as an emergency bag for evacuation in case of a disaster, and I've kept disaster supplies in it for four years. Fortunately, I've never had to take it out, so in a sense, it's unused. It has plenty of storage pockets, making it ideal for school field trips or as a disaster preparedness bag.
