Survival Kit Items – Space Blankets

In an emergency situation, space blankets can be a life saver. In my opinion, every survival bag should have one. They’re cheap, take up little room and they weigh next to nothing.

So what the heck is a Space Blanket?

Emergency Space Blanket

Space Blankets are not like the blankets you use at home. Space Blankets are designed to be used during cold weather emergency situations. They work by reflecting your body’s heat to help keep you warm.

They are also great for:

  1. Lining the roof of a shelter in order to make it waterproof or to reflect the sun.
  2. Reflecting the warmth of a fire into a shelter.
  3. Signaling for Help.

    Can be used to collect rain water.
    I think it can also be used to create a solar still.
