Unlike single use foil blankets, this one is versatile enough for emergencies and strong enough for routine use. Roll it out as a ground sheet on its own or under a tent floor. Rig it as a roof. Wrap yourself in it. Drape it over your gear. Silvered inside surface reflects 80% of your body heat. Orange outer layer makes you easy to spot. Polyethylene top layer resists punctures. Inner woven layer has exceptional strength and tear resistance. Six metal grommets let you rig it as you want it. Reusable, resealable foil pouch included. Survival tips printed on the blanket outline the steps to take during emergency situations.
