Rolled up, the Tuuli Armor looks like any other sleeping bag, but according to its inventor, it can safeguard you from something much harsher than insects and the cold. Apparently, the bag was designed to protect you during tornados, and while it can't exactly prevent broken bones, it can shield you from debris and shrapnel flying faster than 200 mph. That's because it was made using ballistic nylon that soldiers use on the battlefield -- its Missouri-based creator Steve Anderson even bombarded it with bits of wood, metal and glass using an air cannon to test it out.
