This neck cooling tube is made of phase change material to provide you with fast and comfortable cooling. The material freezes at 15°C-18°C and can maintain this temperature for 30-90 minutes while it melts. To activate this effect, simply freeze the neck ring to use, melt it and freeze it to reuse.
The neck cooling tube does not condense, so the neck cooling hose can keep your clothes dry and comfortable and maintain a moderate cooling temperature. Do not worry about frostbite at low temperatures. It has a lower density than water, so it is light.
