Sakazen Hiyatech Cooling V-Neck T-shirt

Body temperature lowering undershirt

Cool biz in Japan means going to work without a full suit and tie. It started as a government-sponsored campaign to encourage Japanese companies to reduce electricity consumption from air conditioners and it became more pressing after the 2011 Great East Japan Earthquake and the damage at the Fukushima nuclear power plant, which affected electricity supplies in Tokyo. The idea has really caught on and every year, millions of Japanese rely on clothing like the Sakazen Hiyatech Cooling V-Neck T-Shirt to make it through the summer without maxing out the air con!

Available in gray and black, the Sakazen Hiyatech Cooling V-Neck T-shirt uses a combination of nylon and polyester that is not only stretchable, but can also stay dry much better than cotton because it breathes more. It's available in six sizes to fit most body types. You can wear a tight-fitting size to wear under your regular shirt or as a more comfortable, loose fit for a casual jeans-and-T-shirt look!
