Features A cooling material for the neck that uses PCM, a new cooling material that is difficult to melt and freezes quickly, instead of ice. Cutting-edge technology PCM material: PCM (Phase Change Material) is a new material developed to protect NASA astronauts from sudden temperature changes. Estimated cold storage time: When used outdoors, the temperature will be controlled at approximately 28 without melting for approximately 90 to 120 minutes. Estimated cooling time: Freeze for about 10 minutes, run under running water for about 15 minutes, or use the car air conditioner for about 25 minutes to cool before use again. There is an aorta in the neck, and cooling the neck can cool the blood flowing throughout the body, which can effectively cool the whole body and help prevent heatstroke. No condensation, so you won’t get wet. Highly durable, lightweight and easy to carry. A comfortable cool feeling that lasts for a long time.
