Reon Pocket by Sony
Sony Corporation is crowdfunding a miniature air-conditioner about the size of a smartphone that can provide some relief from the scorching heat – or at least reduce unsightly sweat stains – that can also be used as a mini heater for colder climates.
The Reon Pocket is a Bluetooth-controlled device that pairs with a smartphone for temperature controls and fits into a special undershirt which has a pocket on the user's back, just below the neck.
