This Emergency Survival Sleeping Bag was initially developed for use by astronauts. The compact size allows you to keep one in your glove box, backpack, purse, desk at work, or just about anywhere! Not only will this Emergency Mylar Sleeping Bag provide protection from rain, cold and wind, it can be used to collect rainwater, repel water off sleeping bags and also provide shade from the sun. Every earthquake kit, hurricane kit or any emergency preparedness kit should contain one of these Solar Sleeping Bags for each person in your family.
