Please choose the size that suits you! Ice neck ring designed to fit around the neck and not easily fall off. Furthermore, it is lightweight and does not put a burden on the neck. Using the latest "PCM material", unlike general substances that rise in temperature with the surrounding humidity, PCM stops at a constant temperature even if the surrounding temperature rises, absorbing heat and maintaining a constant temperature. Also, it does not condense, so you can use it without getting your clothes wet. The cool neck ring freezes naturally below 28°C and can be used repeatedly anywhere, indoors or outdoors. You can use this cool neck ring simply by putting it around your neck. In addition, there is a major artery in the neck, and cooling this part can cool the blood flowing throughout the body, so it can effectively cool the whole body and prevent heatstroke. Cooling duration: 15-20 minutes in the freezer or refrigerator, about 20 minutes in ice water or cold water! Can be used for 60-120 minutes based on an outside temperature of 25-40°C.
