The SOL Emergency blanket is the most advanced emergency blanket on the market. It's a must have if you are ever in an emergency situation outdoors where you need protection from the elements. We always carry a SOL blanket or bivvy in our packs and vehicles. The material is a vacuum-metalized polyethylene(big word) that reflects 90% of your body heat. It's not like your old mylar blanket, this blanket won't shred if nicked or punctured, and rips and if it tears are repairable. It's no crinkley(annoying) and its high-visibility orange exterior makes it easy for rescuers to find you. It's also has some handy info on survival tips and techniques that are printed directly on the blanket so you have them when you need them. Sized for one person. 56" x 84"
