Cooling the world: How SFT Laboratory revolutionizes comfort

Due to the effects of global warming, measures against the summer heat have become essential. In response, SFT Laboratory has developed the world's first Cooling Jacket, ‘Kuchofuku’.

When it's hot, humans sweat, and the evaporation of this sweat helps to lower body temperature. However, if the heat continues, sweat keeps being produced without fully drying, which leads to an accumulation of what we call 'wasted sweat’. We have developed the ‘Cooling Jacket’ as a product to avoid this situation. It utilizes the wind power of two electric fans attached to the back of the jacket to help evaporate sweat.

In particular, in Japan, where it was developed, use of the jacket has spread in industries that involve a lot of outdoor activities, such as construction and electrical work. It rapidly spread to industries that had previously relied solely on ‘drinking water’ to prevent disease.

In 2023, Covid-19 passed its peak and people have become more active again. As such, use of the cooling jacket will not only expand in the B2B market and work situations, but also in recreational scenarios, such as in outdoor sports like trekking and so on. Please consider the ‘Cooling Jacket’ to make your summer activities more enjoyable and safer.

Our products were developed in Japan's manufacturing culture, so we can provide original electrical devices that are safe and contain few defects, as well as our clothing with unique designs that are carefully crafted to maximize effectiveness.
