What cooling technology does 'CORO' use?

It uses a semiconductor called a Peltier element, which can instantly cool when powered, combining active electronic cooling technology with a water circulation system to achieve hybrid cooling.

How does it differ from conventional fan-equipped wear?

Unlike conventional fan wear that 'draws in warm air,' 'CORO' actively cools using a Peltier element, providing reliable cooling even in hot weather. It also features a slim design that does not bulk up, enhancing work performance.

What are the recommended battery specifications?

We recommend a mobile battery that supports PD22.5W and can output over 15W. Using it with the included cooling agent helps maintain stable cooling.

What is the launch promotion content?

We are offering a 50% OFF promotion on Rakuten and Amazon. The promotion period is from May 21, 2026, to June 21, 2026, on Rakuten, and from May 20, 2026, to June 19, 2026, on Amazon.

What applications is it suitable for?

It is suitable for heatstroke prevention in a wide range of settings, including delivery and transportation, caregiving, agriculture, outdoor work, and indoor spaces where air conditioning is limited, such as factory interiors.

Meisei Co., Ltd. has launched 'CORO', a smart cooling vest combining Peltier elements and a water-cooling system. By actively cooling via semiconductors, it addresses the issues of traditional fan-based wear, offering a new solution for heatstroke prevention in extreme conditions.

Meisei Co., Ltd. has launched 'CORO', a smart cooling vest that combines Peltier elements with a water-cooling system.

To overcome the issue of 'sucking in hot air' inherent in traditional fan-based garments, CORO utilizes semiconductors (Peltier elements) that provide instant cooling upon electrification. By offering reliable cooling independent of ambient temperature, it proposes a new heatstroke prevention measure for both harsh professional work environments and leisure activities.

Professional specifications to fight site heat and protect productivity Heatstroke prevention is a critical issue for companies with outdoor operations. While air-blowing wear may fail in extreme heat, CORO physically suppresses body temperature rise through the synergistic effect of Peltier elements and chilled water circulation. This prevents a drop in concentration due to heat and contributes to maintaining site safety management and work efficiency.

Slim design with zero bulk By integrating cooling tubes within the garment, the 'bulge' typical of conventional air-conditioned wear has been completely eliminated. It does not hinder movement even when wearing a full harness or working in narrow spaces. Reflective materials are placed on the front and back to ensure safety at night or in dark places, and the adjuster belt allows for precise fit adjustments according to body type.

Hybrid system: Cooling, circulation, and heat exhaustion The powerful cold air generated by the Peltier elements is circulated as chilled water through the flow paths inside the garment by a high-performance pump. Simultaneously, the rear fan powerfully exhausts the heat generated by the elements. The three mechanisms—cooling (element), circulation (pump), and heat exhaustion (fan)—work in sophisticated harmony to maintain extreme stability in cooling performance.
