Best Emergency Blankets & Bivvies for Cold Weather
Updated Oct 20, 2026 · 3 picks · Prices checked Oct 20, 2026
An emergency blanket works by reflecting your body heat back to you and blocking wind and rain, which can make the difference if you are stranded in a car or waiting for help in the cold. It is not insulation, so it works best wrapped close with clothing or a sleeping bag. Thin Mylar sheets are cheap and tiny but tear easily and trap sweat. The Arcturus Heavy Duty Survival Blanket, TruePrepper's best overall, is a tougher, reusable tarp-style blanket with grommets for a lean-to. The SOL Escape Bivvy is a breathable sleeping sack that cuts condensation. For every glove box and jacket, a SOL Emergency Blanket is thicker and quieter than dollar-store Mylar. Replace any that are torn or brittle.
