The Survive Outdoors Longer 1-Person Emergency Blanket from Adventure Medical Kits is one of the most advanced emergency blanket on the market - meticulously designed by Survive Outdoors Longer® to never fail when you're counting on it most. It all starts with the material, vacuum-metalized polyethylene, that reflects 90% of your body heat while also offering a number of other important features that set it apart from traditional mylar blankets; it opens easily and will not shred if nicked or punctured, rips and tears can be repaired, it is quiet and won't crinkle in high winds, and its high-visibility orange exterior makes it easy for rescuers to find you. More than just a blanket, this is a true ultra-light multifunction backcountry tool that can also be used as a ground cloth, gear cover, first aid blanket, and more.
