Hat Ice Pack Cooling Hat Pad 28°C Natural Freezing Helmet Cooling

Ships with simple packaging.

[Naturally freezes below 28°C! Cutting-edge PCM Material] Utilizes PCM (Phase Change Material) also used in spacesuits. It naturally freezes in environments below 28°C and repeatedly absorbs and releases heat without needing a power source. It can be rapidly charged in about 15 minutes in a refrigerator or about 20 minutes in cold water. It doesn't get too cold like ice, maintaining a comfortable coolness of 28°C at all times, so there's no risk of frostbite and it's safe to touch the skin for extended periods.
[Perfect for Helmets and Hats! With Fixing Button] Specially designed to fit inside general helmets (for cycling, construction, motorcycles, etc.) and hats. Its most distinctive feature is the fixing button. This prevents the pad from falling out of your hat even when you move during work or exercise. Its ultra-thin and lightweight design allows for stealthy attachment without compromising the appearance or comfort of your hat.
[Resists Condensation for Comfort - High-Durability TPU Used] The exterior uses high-quality TPU composite material, also used in medical settings. It is flexible, soft to the touch, and boasts excellent durability and tear resistance. Its biggest advantage is that it resists condensation. Water droplets due to temperature differences are less likely to form, preventing discomfort from wet hair or hats. It's an eco-friendly product that can be washed with water and reused cleanly many times.
[Cool Your Head to Cool Your Entire Body] By efficiently cooling the head, which is close to the brain, it lowers the perceived temperature of the entire body and reduces the risk of heatstroke from extreme heat. It alleviates physical stress in harsh environments such as outdoor work under the blazing sun, agricultural work, cycling, and sports viewing, supporting the maintenance of concentration and work efficiency.
