It automatically freezes at 28°C or below, providing a sustained cooling sensation for approximately 60-120 minutes. The temperature-sensitive "liquefaction ⇄ solidification" cycle provides smart cooling that is gentle on the skin. Unlike conventional ice packs, it doesn't get extremely cold, so it's safe. As a next-generation cooling garment, it's ideal for heatstroke prevention and is a must-have item for outdoor workers. 【Decomposable and Washable Design! Next-generation Cooling Vest】 The vest body can be washed by removing the PCM cooling unit. It can be washed, so it's hygienic even after repeated use. The removed PCM cooling unit can also be used separately as a "cooling mat." 【Sustained Cooling Without Power, Making Intense Heat Work Comfortable】 When liquid, it can be easily frozen in environments below 28°C, such as a refrigerator, a place exposed to air conditioning, or cold water. Cooling in the refrigerator allows you to enjoy the cooling sensation for even longer. It has a better cooling effect than ice packs, maintaining proper cooling and preventing excessive cooling. It freezes naturally just by placing it in an environment below 28°C, even during a power outage, so it can be used with peace of mind during disasters or under power restrictions. High-intensity reflective tape is placed on the front and back. It ensures visibility in the dark, reducing the risk at construction sites and during nighttime deliveries. 【Free Size & 1 Million Reuses】 Free size, for both men and women. Reusable over 1 million times, it's an economical and environmentally friendly heatstroke prevention product. The cooling vest, which can be reused many times, also leads to long-term cost savings. #rui_home
