Mecalink Co., Ltd. (Headquarters: Toranomon, Minato-ku, Tokyo; Representative: Sei Sugita) will launch "COOLER MASTER," a new generation wear that combines cold air and cooling technology.
Developed as a heatstroke countermeasure for working in scorching environments and outdoor activities, this product differs from conventional fan-equipped workwear. It adopts a portable cooling system that combines a cooling unit and a ventilation system. It is a new generation backpack-type air-cooled wear that envelops the body with a cooling performance of up to -14℃ from the ambient temperature.

■ New Challenges in Scorching Environments
In recent years, Japan's summers have seen record-breaking heat, and the risk of heatstroke for people working outdoors has become a social issue.
The Japan Meteorological Agency defines days with a maximum temperature of 35℃ or higher as "scorching hot days," but in recent years, regions observing temperatures of 40℃ or higher have increased. The agency has even announced that days with maximum temperatures of 40℃ or higher will be named "extreme heat days (kokushobi)," drawing more attention to the dangers of heat than ever before.
Indeed, in Japan, temperatures exceeding 40℃ have been observed in various regions in recent years, making extreme heat a norm, and the number of emergency transports due to heatstroke is increasing.
In this situation, for people working outdoors in construction sites, logistics, agriculture, etc., environments where conventional heatstroke measures are difficult to cope with are increasing.
Traditional air-conditioned wear had issues such as being easily affected by ambient temperature, not being able to directly cool the body, and having limited effectiveness in high-temperature environments close to 40℃. Therefore, this product was developed to support heatstroke countermeasures for outdoor workers by suppressing the rise in body surface temperature even in scorching environments, by adopting a unique system that combines a cooling unit and ventilation function.
■ Features of the New Generation Backpack-Type Air-Cooled Wear

1. Hybrid Structure of Cooling + Ventilation
While general air-conditioned wear primarily works by drawing in outside air and blowing wind, this product adopts a hybrid structure that combines a cooling unit and ventilation function.
By generating cold air from a cooling unit mounted on the back and circulating that cold air inside the wear, it achieves a new cooling method that efficiently dissipates heat while directly cooling the body.
By circulating cold air particularly in the three main cooling areas—neck, back, and torso—which are prone to feeling hot, it suppresses the rise in body surface temperature mainly in the upper body. This reduces heat buildup in the body even in scorching environments, supporting more comfortable outdoor work and activities.
2. Unique TorCosys Cooling System
This product adopts "TorCosys (Torso Cooling System)," a unique technology developed by COOLER MASTER. By circulating the cold air generated from the cooling unit through an air duct structure inside the wear, it is designed to efficiently deliver cold air to the body surface. This structure enables "direct body cooling, improved cooling efficiency, and stable cooling in hot environments," which were difficult with conventional fan-equipped wear.
Furthermore, by circulating cooling air inside the wear, it provides a new cooling experience that creates a cooling space around the body.
3. Long-Lasting Battery with up to 20.5 Hours of Operation
This product is compatible with commercially available mobile batteries and can operate continuously for up to 20.5 hours.
It is designed for all-day use during long outdoor work, events, and outdoor activities. In addition, the airflow can be adjusted in three stages, allowing users to set the optimal airflow according to the usage scene and environment, such as "outdoor work, commuting to school/work, sports spectating, and outdoor activities."
Battery replacement is also easy, making it suitable for long-term use at work sites and event venues.
Developed as a next-generation heatstroke countermeasure wear that can be widely used from work sites to daily life, as extreme heat and temperatures above 40 degrees become the norm.
■ Cooling Effect Confirmed in Verification Tests
1. Temperature Measurement Experiment
In temperature measurement experiments using thermography, a decrease in body surface temperature was confirmed by wearing the backpack-type air-cooled wear.
Cooling effect experiment data
2. Long-Duration Measurement
In tests under high-temperature environments, the cooling effect was confirmed to last for a long time.
Experiment data over time
■ Active in Various Scenes
Utilized for sports and walking, etc.
This product can be used in daily life and outdoor activities such as construction sites, factories, warehouse work, agricultural work, security services, delivery/logistics, traffic guidance, fishing, cycling, camping, sports spectating, outdoor events, and commuting to school/work. As extreme heat becomes the norm, it is expected to be widely used as a new heatstroke countermeasure wear that can be used from work to daily life and leisure activities.
