Well, the one I bought works damn well for heat and had one huge advantage over wool. I can bungee cord it to my car and be very, very visible to any search going on to find me. I would hope people going out in winter also have proper coats and pants, but extra blankets as well a proper survival kit is a very good thing. Small grain shovels are also quite nice.
