"2025 New Model / PCM Cooling / No Power Required" The latest cooling vest for 2025. A PCM vest is an inner vest that provides a cooling sensation using phase change material (PCM). Developed by applying space suit technology, it is useful for heatstroke and heat countermeasures. Compared to conventional PCM vests (which can only be used for 2-4 hours) that use 100% PCM, this cool vest uses a mixed material of PCM and absorbent cotton. After soaking in water and absorbing it, the advantage is that it can maintain a 27°C cooling sensation for over 24 hours until the water completely evaporates. Also, because it cools the body through physical cooling, it does not require a battery and is convenient to use. You don't have to worry about battery explosions or sudden malfunctions. It is safe and highly recommended for energy saving. "27°C Cooling / Sweat Evaporation / 24-hour Use" This cooling vest maintains a temperature of approximately 27°C. It can be used for over 24 hours after soaking in water once. This is 12 times longer than conventional products that can only be used for 2 hours! The hassle of re-cooling when the cooling sensation disappears has been significantly reduced. General materials absorb heat and the temperature rises, but this heatstroke countermeasure vest has excellent characteristics because it automatically maintains a temperature of around 27°C even when absorbing and releasing heat. It achieves skin-friendly 27°C cooling without the discomfort of being too cold. "Just soak in water for 5 minutes / Removable PCM / Convenient to wash" After soaking in water for 5 minutes, the PCM blocks will automatically expand by absorbing water, and you can start using it immediately after wiping the surface water. It's quite convenient. If you want more cooling, ① soak in water and then put it in the refrigerator/freezer (for 10 minutes or more) ② or soak it in water with ice from the beginning. This cooling vest is a removable type. It is easy to soak only the PCM blocks in water or put them in the refrigerator. After removing the PCM blocks, the vest itself can be washed in a washing machine, which is convenient.
