This compact, ultra-lightweight, 60g Arva survival blanket will follow you on any adventure. With the gold-colored side facing out, the survival blanket captures the sun’s infrared rays to warm up the rescue victim while the silver-colored side reflects 90% of their body heat. In the event of extreme heat, you may want to prevent the body from heating up too much. In this case, place the gold-colored side against your body to let heat escape and the silver-colored side facing out to reflect the sun’s infrared rays. Warning: do not use this survival blanket during a thunderstorm or near incandescent materials.
