@secondwavevintage: Kuchofuku Air Conditioned Jacket First launched in 2004 by Hiroshi Ichigaya, the jacket was originally designed to keep Japanese labourers cool during Japan's hot summers. The jacket has a personal air-conditioning system with two built-in cooling fans. This circulates air throughout the jacket, helping to evaporate sweat! This provides a more energy efficient cooling method to traditional air conditioning systems.
