The inner layer is made of a special form of nanometer materials and magnetic. When the temperature is below 25 degrees celsius, between the molecules will have mutual collision, so that the temperature is maintained at 25 degrees celsius.So in a world of ice and snow, you wear is enough.This collar is made of ZnO nanometers corpuscle that can absorb oxygen.On the plateau, it can absorb the surrounding oxygen and release it on the other side. So you won`t have high altitude reaction.
