Welcome to the blog, Colorado Preppers. Prepping doesn't mean we think the apocolypse is coming or the earth will blow up. It simply means that we are preparing for any eventuality that may strike here in Colorado (USA) ... from swine/bird flu to blizzards to global financial collapse to loss of income and more. // Come learn with us about things like water purifying and collecting, inventory checks and more.

Inventory Check: Space Blanket

A space blanket isn't really a blanket. It's more like a covering that's made to reflect radiant energy (heat).

Two sizes:

  1. They come folded up to fit in the palm of your hand, and open up to cover your body, and more. It's shiny, and made from a Mylar plastic, coated with aluminum, that reflects up to 80% of your body heat. It's shine also is great at signalling.
  2. A larger version is a big bigger when folded, so takes up more space in your supplies. It isn't as reflective or as shiny, but it is more durable. It's made out of a tougher woven material, and has grommets in the corners to allow for tying down. These are smaller than a tarp but can cover 2 people easily. They can also be used as a ground cover, windbreak or body wrap. They also keep rain and snow off in a pinch. These come in neon-type colors which will help signaling for rescue.

Use these to insulate you against cold OR to reflect heat from, say, a desert, away from you. You could also use them to line a solar oven, disinfect water, or reflect the sun when hung in your windows.

I've found these at Wal-Mart for .99 cents each. I grab all I can find when they are in stock; usually, that space is empty!

In my opinion, you can't have too many of these.

This is a great reminder that so many items have so many purposes. We all should have several on hand!

Very true, mylar space blankets are handy for many things.
