The Reon Pocket

To help consumers in Japan beat the summer heat, Sony’s First Flight start-up incubator launched the Reon Pocket, a wearable air conditioner that works in tandem with its v-neck t-shirts that can either be worn on their own or under another shirt to completely hide the device from view.

The specially designed t-shirts include a small pocket near the back of the neck, where the slim AC gadget fits snugly. Once activated, the Reon Pocket can be controlled with Sony’s associated app.

As Sony claims. the gadget is capable of reducing the body’s surface temperature by 13°C. In addition to being used inside of Sony’s t-shirts, the mini air conditioner can also be used as a handheld device.
