This multi-pack of 83" by 37" Emergency Sleeping Bags will help make sure you have one for yourself and a few extras to share with family and friends. Manufactured from the same quality ultra-light thermal reflective film as emergency blankets, our emergency bag has been specially fabricated to provide full body coverage when one is at rest. The full body design allows for maximum retention of body heat. Weighing a mere 3 ounces, its convenient folded size (approximately 5" x 3.5") fits well in a hiking backpack, first aid kit, car glove box or 72-hour kit. Most notably utilized to help prevent hypothermia, there are many other reasons to carry this handy item. Among its many benefits, you can use it inside or over a conventional sleeping bag to add thermal performance. A great lightweight moisture barrier, the bag is practical as a waterproof windbreaker as well as an emergency signaling device.
