Breath Thermo is a cutting-edge technology exclusively developed by Mizuno in Japan. It is a unique heat-generating fiber with insulating properties, which generates warmth by absorbing the slight moisture (water vapor) emitted from the body. The moisture absorbed creates air pockets between the fibers, providing additional warmth to the garment.
