Product Introduction Page
Product Overview
In recent years, fan-equipped apparel has become widespread in construction sites, factories, and logistics warehouses. However, in extreme heat environments, further heat countermeasures are required.
The "Liquid Wind Soothing Vest," when worn as underwear with fan-equipped apparel, achieves efficient cool-down by combining airflow and evaporative cooling. It supports body cooling and contributes to improved comfort for those working in harsh environments.
Main Features
● Evaporative Cooling Experiment Results: Achieves a surface temperature reduction of up to -5.2℃ on underwear*
*Experiment conducted at an indoor temperature of 35°C / humidity of 70% / wind speed of 6m/s (equivalent to 20 km/h). The graph and temperature difference data are measured values in a test environment by one subject. Effects and usability may vary depending on the wearing environment. The graph was created by RS TAICHI Co., Ltd. based on the "Thermographic Fabric Surface Temperature Analysis Results" (Consumer Science Research Institute Co., Ltd.).
● Supplies Special Cooling Water to Chest and Back for Evaporative Cooling
Cooling water is supplied from a cooler bottle worn on the waist to the underwear on the chest and back through tubes within the vest. The evaporative heat generated as the cooling water evaporates provides an efficient cooling effect.
● Cooler Bottle with Automatic Water Supply Function
The cooler bottle equipped with an electric pump automatically supplies water approximately every 5 minutes, allowing for cooling water supply without user intervention. One cooler bottle can be used for approximately 4 to 5 hours.
The cooler bottle features a drip-proof design compliant with IPX4. It is designed with consideration for outdoor work environments.
● Utilizes Special Cooling Water Jointly Developed by RS TAICHI and Mandom
This product uses "LIQUIDWIND WATER," special cooling water jointly developed by RS TAICHI Co., Ltd., a motorcycle apparel manufacturer, and Mandom Corporation, a manufacturer of men's cosmetics.
The cooling water features Mandom's proprietary "Kai-tech Air" technology, providing a comfortable cool sensation that lasts for a long time with a refreshing formula containing cooling ingredients (menthol). Furthermore, it contains double deodorizing ingredients to suppress odors in the apparel, is fragrance-free, non-sticky, and offers a comfortable feel even while riding. The menthol component ensures long-lasting coolness, and the double deodorizing ingredients are included. Its fragrance-free nature makes it easy to use even in work environments. The menthol component provides a long-lasting cooling sensation, and double deodorizing ingredients are included. As it is fragrance-free, it is designed for comfortable use even in work settings.
