I’ll make my list of the first nine survival items that you should buy really simple for you.

The first two big-dollar items that you should buy are the Self Reliance Outfitters Canteen set and heavy duty space blanker/tarp. These two items are really must-have items. Dave Canterbury of Self Reliance Outfitters had these items custom-made. They are industrial strength and designed just like I would have done so myself.

The canteen. It is similar to the old metal army canteen setup. But it is bigger and has a bigger mouth. It is nested in a canteen cup with a handle for drinking from and to use for cooking food and boiling water. You get a cooking cover too, to go over the canteen cup. Then you get another stacking cup with holes in it that serves as your cooking stove. So you can cook with twigs. The idea is that the canteen cup sits on top of the Stove. A ferro rod is included with the canteen along with some sort of cordage.
