I am no fan of space blankets. That said, I tested the Blizzard Bag and came away with a positive opinion.Forum readers may want to read that thread before screaming garbage and rattling credit cards at the retailers. Once again, The BB meets a specific need; compact emergency units for people who hopefully are wearing winter clothing. If you don't like one use items carry either a dedicated sleeping bag and tent or a body bag. A garbage bag seen without the prejudical contents equated with a BB is just that. I truly want to see an injured or hypothermic victim gather leaves in the high wind, white out conditions of say, The Pennines of the U.K.
