One time, a friend and I were out doors, and it was bitter
cold, and blowing. We left the truck, and walked across
an open field, might have been ten degrees. I had a coat
on, and brought an old bed comforter, which was yarn
and lots of holes in it. That was just useless. Made me think
that a blanket for rescue should be wind proof.
The appeal of the yellow emergency blankets, is the plastic
layer should make it wind proof. A big of fuzzy, to make it
warm. Or, so the theory goes.

I bought a bunch a long time ago, the shiny ones. I read something about
body fluids on the yellow ones, yikes. The good, they don't take up much
space. Space ? Yes, take off all your clothes and you will be warm, not.
I bought a large full size winter coat long ago, with reflective layer on
inside. I'll take that when I need warmth.
If your naked and sweating after a long run, I guess the blanket is the
ideal quick fix. Wind break plus heat reflection.
The only time you'll get enough heat reflection is with an air gap on naked
skin. If your already wearing a coat, ir radiation is going to be minimal,
thus space blanket useless, unless it acts as wind break. They say, 90%
heat retention, that's ir radiation, not conduction, or convection.
For one reason or another, I have had a nice warm blanket in the trunk. It
was something I had leftover from traveling. Regardless if you use it to
protect something, or keep something from moving around the trunk, or
emergency warmth, I would recommend one. Throw a couple space blankets in
