VERY COMPACT AND ULTRALIGHT, THE 60G SURVIVAL BLANKET WILL FOLLOW YOU IN ALL YOUR ADVENTURES.
By putting the golden side outwards, the survival blanket will capture the sun's infrared rays to warm the rescued person while the silver side will reflect 90% of body heat. In case of high heat, you may want to limit the heating of the body. In this case, put the golden side against you to let out the heat emitted by the body and the silver side to reflect the infrared rays of the sun.
Caution: Do not use during thunderstorms or near incandescent materials.
