It all starts with the material - vacuum-metalized polyethylene reflects 90% of your body heat while also offering a number of other important features that set it apart from traditional mylar "space" 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. Weight: 3.5 oz - Size: 60" x 96"
