Looking to warm up with a pretty girl while star gazing? Or maybe your LT got you lost and you're trying to make sure your sack doesn't freeze off? All jokes aside, @emergencyzone
asked me to do an honest test and review of their Heat Saver survival blanket. I'm yet to finish, but I'm liking it so far. I used it in 40 degree weather with 100% humidity and light rain, and I was sweating. These obviously aren't extreme conditions, so I will continue to test. I am pleased with the results so far.
