With a hidden in a built-in pocket on a specially designed t-shirt, the Reon Pocket will be able to lower your personal body temperature by 23 degrees or raise it by about 14 degrees.
Instead of blowing processed air like your apartment building's AC, the body-mounted device uses what's known as the Peltier effect. The effect creates a temperature difference by transferring heat between two objects using electrical currents.
Currently being crowdfunded. Expected to ship 2020.
