DESC: SPACE ® Brand EMERGENCY BAG is manufactured from the same high quality polyester film as the EMERGENCY BLANKET, but it has been specially fabricated to form a bag to provide full body coverage when one is at rest. The emergency sleeping bag concept can be used inside a sleeping bag, over a sleeping bag, or by itself in an emergency situation. The full body design allows for the maximum retention of body heat and like other Space® products, acts as a windbreak against the biting cold winds. The length is a full 7 feet and the width is 3 feet, yet the folded package size is less than 4 inches by 3 inches by 2 inches, and it weighs just 3 ounces. This is an ideal product for adding safety to your outdoor adventures. Windproof, waterproof and flexible to -60 degree F. This bag reflects back 80% of body heat. Invented for NASA and manufactured from the finest polyester material and purest vacuum deposited aluminum for the reflective surface, this product has helped to save countless lives,
