The SOL Emergency Blanket is meticulously designed never to fail when you're counting on it with your life. The vacuum-metalized polyethylene material reflects 90% of body heat and, unlike traditional blankets, will not shred if nicked or punctured and rips and tears can be repaired. It is waterproof, quiet and won't crinkle in high winds, and its high-visibility orange exterior makes it easy for rescuers to find you. This blanket is a true ultralight multifunction backcountry tool that can also be used as a ground cloth, gear cover, first aid blanket, and more. Sized to fit one person.
