With earthquakes and disasters happening more frequently of late, it's a worthwhile investment to get this $6 Heatsheets Survival Blanket. It will also come in handy if you get lost on a camping or skiing adventure. The reflective blanket is roomy enough for two people, because it's always more fun to be trapped with someone else.
What I like best about the design is that survival and first-aid instructions are printed directly on the blanket, so you do not have to look around for a leaflet. You can always access them right on the blanket if anything happens.
The bright orange (you would want to be easily spotted under such circumstances) blanket reflects up to 90% of radiated body heat, ensuring you stay warm inside. It is also tear resistant and is very compact when folded.
