Sony Reon Pocket is a crowdfunded wearable air conditioner and heater

Whether you believe in climate change and global warming or not, it's difficult to deny that temperatures and weather patterns these days are drastically different from years ago. More commonly, hot days are even hotter but sometimes even cold ones can become unbearable. Those may be of no problem if you stay indoors but the moment you step out, you're mostly on your own. That's why a few folks at Sony have thought up of the Reon Pocket which, believe it or not, promises to offer an air conditioner you can discreetly wear on your back.

Technologies and materials today have become so advanced that they can affect our body's physiological states with just a tap of a smartphone button. That's pretty much the idea behind Reon Pocket which uses Peltier, an element used for car and wine coolers. The material uses small amounts of power and can be used over long periods of time.

Reon Pocket works simply enough, which probably adds to its almost unbelievable promise. After just 2 hours of charging, you slip the soft device into the pocket of a specially made undergarment. You can then wear anything else on top of that shirt and use the smartphone app to control the temperature.

It won't just cool you off on hot days. It can even warm you up on hot days. The device is thin enough to wear underneath any other clothes but you'll need to wear that special undershirt to make sure it is positioned properly and securely. Good thing it can cool you down during hot days because you'll probably need to offset that extra layer of clothing.

The Reon Pocket is currently available from Sony's First Flight crowdfunding platform, which means it's only available in Japan. Considering one device and one shirt costs 14,080 JPY or $130, that may be just fine.
