Starting March 27: A New Proposal for 'Wearable Heat Countermeasures' in the Workplace – Launching Contact Cooling Functional Innerwear

Relive Co., Ltd. (Headquarters: Sendai, Miyagi Prefecture; Representative Director: Takashi Sasaki) will launch 'Cool Fit Inner,' a new product in its line of functional wear designed to support blood circulation, starting March 27, 2026 (Friday) via its e-commerce site and authorized retailers.

In recent years, record-breaking heat has become the norm in Japan, and working environments during the summer are becoming increasingly harsh. In sectors that rely on physical labor—such as nursing care, medical services, construction, and logistics—workers face the dual burden of long hours of standing, movement, and physical assistance, compounded by high temperature and humidity. This makes fatigue and physical health management major challenges for employees.

In these environments, air conditioning alone has its limits, making it crucial to find ways to 'work while reducing the burden on the body.' However, many workers report limited options for improving comfort due to strict uniform requirements and professional constraints.

Against this backdrop, our company has focused on innerwear, developing the 'Cool Fit Inner' using fabrics designed for breathability, moisture absorption, and reduced stress during wear. This product is designed to minimize discomfort on the skin even in sweat-prone environments, maintaining comfort during long hours of use. It represents a new approach to 'responding to environmental stress through clothing' by focusing on the challenges of summer conditions.

We anticipate that this product will be widely adopted in fields with high physical demands during the summer, such as nursing, medical, construction, and logistics. We are also exploring its potential for use in a wide range of daily life scenarios as a general heat-countermeasure solution. We remain committed to developing products that reduce physical burden across various settings, from daily life to the workplace.
