Our space bag, also known as a Mylar bag (or first aid, safety, thermal, or weather bag), is a light, airy, bag made from heat-reflecting plastic. The thin sheet of plastic is coated with metallic reflector known as metal coated polyethylene, which reflects up to 97% of radiated heat.The design of the space bag helps to reduce the loss of heat in a person's body due to thermalradiation, evaporation, or convection. The bag was first developed by NASA's Marshall Space Flight Center in 1964. Great for maintaining temperature during heated stone massage.
