This material solidifies quickly and melts slowly. The neck cooling ring is a product that cools the neck, making it an ideal item for preventing heatstroke and heat exhaustion. Our product uses natural PCM extracted from plants, which is safer and free of harmful substances compared to conventional PCM extracted from petroleum. 【Gentle 28°C】There are 28°C, 24°C, and 18°C PCM products on the market, but 28°C provides a relatively gentle and comfortable temperature, without the risk of overcooling or frostbite. Products with lower solidification temperatures need to be placed in a freezer or ice water to harden, which can cause condensation on the outside. However, our 28°C ice ring will begin to solidify at temperatures below 28°C when placed in a cool place such as an air-conditioned room, allowing you to enjoy coolness more easily and continuously. Furthermore, the product is treated to prevent condensation, effectively preventing condensation caused by changes in environmental humidity, so you don't have to worry about getting your clothes or hair wet. 【Innovative structural design upgrade】The product's structure has been upgraded with a new design! ① Double ring structure. Compared to the conventional single-ring structure, the double-ring structure significantly increases coolness and duration, and the inner ring is fluorescent, ensuring high visibility and safety in dark environments. This is especially suitable for night running and outdoor activities at night. ② Multi-layer structure. The product uses high-quality multi-layer composite TPU material, making it more flexible and comfortable to wear, less prone to deformation, less prone to aging, less prone to leakage, and does not form condensation. Durability and comfort are significantly improved compared to products with a conventional single-layer structure.
