I always include at least two Space Blankets in my gear and often a bivvy of the same material. My thinking is to use one as a ground cover or blanket and the other as a tarp. Having experimented with them in a variety of conditions I'm under no illusion that they'll keep my toast and comfortable but they can keep me dry, and perhaps provide that margin of survival. Also they can be used to make a Palmer Furnace provided I have the other associated stuff (and I do usually have a couple of beeswax tea light candles).

A very old thread indeed. A bit melancholy seeing OBG's post but in a good way.
