Use high, reflective materials to shoot heat arrows back. I have one, me? And the first aid on the blanket uses these two principles. Aluminum, its main one, is aluminum, reflected radiation, its heat reflection is up to, can reflect the body's warm eyes reflection back, thermal efficiency up to the same, Some of it, it doesn't. Therefore, it is connected by metal countries, so it is easier to break and the strength is not high. Therefore,
