[Industry's First Cooling Vest Arriving in 2026] Smartly conquer this summer's heat! Cooling vest makes its debut in Japan! This is a cool product, uniquely developed by the industry in 2026, perfect for preventing heatstroke and coping with the summer heat. It uses a new PCM cooling material, independently developed based on NASA's cooling technology. It automatically freezes below 28℃ and provides sustained cooling for approximately 60-120 minutes. The temperature-sensing liquefaction ? solidification cycle provides smart cooling that is gentle on the skin. Unlike conventional ice packs, it does not reach extreme low temperatures, so it is safe to use. As a next-generation cooling garment ideal for heatstroke prevention, it is an essential item for outdoor workers. This cool vest demonstrates its true value in environments where heat countermeasures are essential, such as construction sites.
[Hygienic with Washable Design] This cool vest has a detachable design. By removing the PCM cooling unit (large capacity of approx. 41x30cm), the vest itself can be washed with water. It can be kept clean even with repeated use. The removed PCM cooling unit can also be used independently as a cooling mat.
No need to worry about bothersome fan noise or battery depletion. Safety risks from battery overheating in high-temperature environments are completely eliminated. In its liquid state, it easily freezes in environments below approximately 28℃, such as in a refrigerator, under air conditioning airflow, or in cold water. Cooling it in the refrigerator allows for even longer-lasting cooling. Unlike conventional ice packs, it does not reach extreme low temperatures and maintains cooling at an appropriate temperature. The skin-friendly cooling sensation lasts for a long time.
This cooling vest is equipped with Velcro on the shoulders and waist, making it a free size that can be adjusted freely. It fits snugly to your body shape. Furthermore, it is equipped with a large PCM unit (approx. 41x30cm). With a wide cooling area, it covers a large part of your body from your back to your abdomen, achieving strong and uniform cooling, unlike products with narrow cooling areas. Even after it melts, it refreezes simply by placing it in a cool place with air conditioning and can be reused over 1 million times. It is economical and environmentally friendly, and recommended for those who dislike the wind from air conditioners or fans. It is a practical and popular summer item that also contributes to saving electricity costs.
