Simply place the cooling sheet in your hat and put it on, and you'll instantly feel a refreshing coolness from your head to your entire body. This efficient physical cooling experience eliminates discomfort caused by high temperatures and can even prevent heatstroke. Simple to use, it provides a powerful cooling effect, allowing you to spend a cool summer. [Four Freezing Methods & Reusable] Made from PCM phase change material, it naturally cools below 28°C. There are four freezing methods: placing it in the freezer, in ice water, in the refrigerator, or in an air-conditioned room. The cooling sheet will quickly freeze naturally in just a few moments. After being exposed to heat, the PCM content transforms from solid to liquid, allowing it to be cooled again and reused. [Sustained Cooling] The cooling effect lasts for up to 90 minutes, even in summer temperatures. The long-lasting cooling effect ensures a constant cooling sensation. The unique design ensures the flow of cool air. (Note: The operating time may vary depending on the ambient temperature.) Lightweight, Soft, and Waterproof: This cooling hat pad is 40% lighter than water, so it won't feel heavy when you put it inside your hat and put it on your head. The cooling sheet's contact surface is made of TPU material, which is soft, flexible, and gentle on the skin. The surface is condensation-free and waterproof, and does not absorb water, so you can wipe away sweat and dirt at the same time. [Applicable in a variety of situations] This is the perfect measure against heatstroke in the summer.
