The SOL Emergency Blanket is the most advanced emergency blanket on the market, meticulously designed to never fail when you're counting on it with your life. It all starts with the material, vacuum-metallised polyethylene, which 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. XL is sized to fit two people.
