Measuring 52 inches by 82 inches, these emergency foil blankets keep you warm in a pinch. Lightweight and compact, they come all folded up in their own easy-seal bags, making them easy to carry or hand out on the go. One reviewer calls them “effective in cold weather,” as well as small and plenty useful. Others say they’re a great safety item to have on hand and are worth having a couple with you, “just in case.”
They work by “trapping” the heat your body gives off and reflecting it back to you.
Tear-resistant and wind- and waterproof, these blankets provide a physical barrier from the weather. However, the main draw is that they’re non-breathable and reflective, engulfing your body’s heat without letting it escape.
While the blankets are made from a thin plastic, often known as “mylar”, they’re covered in a bendable layer of shiny, thermal aluminum that keeps you insulated when it’s wrapped around you.
Hot tip: You’ll want this to be like a sleeping bag, completely tucked in and wrapped around, ensuring no cold air gets in or hot air gets out.
