## 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.
