[Kuchofuku Co., Ltd.] Cooling with just tap water! Launching the new heat protection wear, Kuchofuku(R) Vest (with evaporative cooling liner) on May 29th (Fri)!

Product Overview Kuchofuku Co., Ltd. will launch the 'Kuchofuku(R) Vest (with evaporative cooling liner),' featuring a special evaporative film, on May 29, 2026, through its official e-commerce sites (Rakuten and Yahoo! Shopping).

Background of Development With the increase in extreme heat in recent years, outdoor working environments have become more challenging. We developed this product to meet the demand for cooling performance exceeding that of conventional Kuchofuku(R).

Key Features By combining the vest equipped with the special 'VapeSeal' evaporative film as a liner, sweat and moisture are efficiently evaporated by external air from the fan, providing cooling performance below ambient temperatures. It offers a 3-way specification: Kuchofuku(R) alone, the cooling vest alone, or a combined setup.

Effectiveness Tests in a 35°C, 60% humidity environment confirmed superior temperature reduction when using the combination. Moisture from the liner penetrates the Kuchofuku(R) material, enhancing evaporative cooling performance.

Convenience and Comfort Provides approximately 4 hours of usage with 300ml of tap water. The eco-friendly design requires no additional batteries. The internal pintuck structure prevents the vest from sticking to the skin while maintaining appropriate moisture levels and suppressing stickiness.
