Our PCM cool vest can be cooled in the refrigerator for about 30 minutes, providing an instant cooling sensation upon wearing. With its long-lasting cooling effect, it effectively lowers body temperature even in the scorching sun, preventing heatstroke. 【PCM Cooling Material & Natural Freezing Below 28°C】 We use the cutting-edge PCM material developed by "NASA, the US National Aeronautics and Space Administration." Ordinary materials absorb heat and their temperature rises, but PCM material has the excellent characteristic of automatically maintaining a temperature of around 28°C even when absorbing and releasing heat. This product maintains a temperature of about 28 degrees. It achieves skin-friendly 28°C cooling, without the discomfort of being too cold. Freezing automatically starts in environments below 28°C (such as air-conditioned rooms), extending the usage time by more than double compared to conventional products. 【No Charging Required & Reusable】 Preparation is complete by freezing in the freezer for about 20 minutes before use. No electricity or water replenishment is required, and using an ice-water mixture is highly recommended! After use, it can be reused repeatedly by simply cooling it again in the refrigerator, making it an economical and environmentally friendly design. The internal phase change material (PCM) changes from liquid to solid during cooling and from solid to liquid during use, always providing optimal cooling effect. 【Condensation Prevention & Long-lasting Cooling】 The special material of this product is less prone to condensation during cooling, so you don't have to worry about your clothes getting wet at all! It achieves excellent cold retention performance that lasts up to 120 minutes (※ varies depending on the environment) once cooled. You can extend the cooling time further by freezing it in the freezer. $$3680
