I bought the heavier SOL emergency blanket last year thinking it might do double duty as a tarp to keep the boned out meat clean. Shot a large cow and found out the reflective properties of the fabric really work. The meat wouldn't cool at all sitting on the blanket. It suffered enough damage that I won't use it again for that purpose anyway. I think it would be nice to have in a cold emergency situation but can't say exactly how it would perform.
