The EMERGENCY BLANKET survival blanket weighs just 70g, is very compact, and as light as most single-use survival blankets. Strong enough to be used over and over again, it is capable of reflecting 90% of body heat when the silver side faces in.
When backpacking, this survival blanket can be placed under your tent with the silver side facing up to insulate you from ground humidity and reflect heat.
Warning: do not use this survival blanket during a thunderstorm or near incandescent materials.
