This survival kit contains most of what you need. The ony two things missing are water purification and shelter. I keep this kit in a plastic bag, used for water collection. With it are a bottle of water purification tablets (also purchased at WalMart), some tin foil to make a pot/bowl (boiling water), and a heavy duty trash bag for shelter. This is the most complete kit available for the money. Plus being sealed in a can means it's water tight. The can is very durable and could double for a bowl or cup if needed. If you want a small, lightweight, practical survival kit, buy 1... You might even want to buy a few. I did.
