Simply put, Sony‘s Reon Pocket air conditioner, the first product for the company’s First Flight crowdfunding platform, aims to keep you cool during the warm summer months. It’s designed to fit snuggly into the back of a custom undershirt and uses thermoelectric cooling, all controlled via Bluetooth on a smartphone. You’ll be able to cool down or warm up with just a few swipes of your finger. How cool does it get? Allegedly, it can lower your body temperature by up to 23° Fahrenheit, or raise it 14° Fahrenheit.
