The company's First Flight program is crowdfunding a wearable 'air conditioner,' the Reon Pocket, that slips into a pouch in a special t-shirt. The stealthy device doesn't condition the air as such. Rather, it sits at the base of your neck and uses the Peltier effect (where heat is absorbed or emitted when you pass an electrical current across a junction) to either lower your temperature by 23F or raise it by 14F, all without bulk or noise.

It’s always…cool (heh heh, still got it) to see technological innovation like this. A wearable AC would have been nice to have here in St. Louis these past couple weeks. It’s neat also that the device can warm you up. Not a terrible price either at approximately $117 USD.

Too bad it’s not shipping until next year, and even then, just in Japan.

The two-hour battery isn’t exactly jaw dropping, but if they can make the battery or the tech powering this thing more efficient, it’ll be a must-have, especially when you think about how we’re still not taking climate change seriously.
