The versatile, lightweight Survival Blanket 2.0 provides all-weather protection by reflecting your own body heat back to you. Windproof and waterproof, it can also be used as an emergency lean-to shelter, ground cloth, additional warmth for sleeping bags, and for wrapping cold or frozen food during transport. It's ideal for carrying in a day pack for emergencies, or as part of an emergency kit for your car or home. Durable for multiple uses, the Survival Blanket 2.0 has a three-ply construction, with one layer each of polyethylene, reinforced fabric, and metalized polyester. Use for warmth or shelter in emergency situations. You can make a lean-to shelter by lashing ropes through the corner grommets, and it reflects heat up when used as a ground cloth. Weighing 13.6 ounces, it measures 60 x 83 inches. It's backed by a two-year manufacturer's limited warranty.
