Pocket survival kit in an Altoids can. Would be cool to carry in a purse to have on hand all the time for absolute emergencies. There are a lot of other good tips in the comments. One guy explains how you can repel from a cliff with parachute cord, a carabiner, and some climbing knots. Way cool.
This is a really good (and smart) idea. Everyone should have at least a Rubbermaid bin filled with emergency supplies but these backpacks are a great idea. I'd label each one with the appropriate family member's name (since some items might be different in each bag). Great idea.
