Thanko Armpit Cooler Backpack

They are one of the hardest spots in our body to keep from sweating the moment the temperature even hints at the beginning of spring, let alone the heart of summer. Even if shaved completely, our armpits sweat and make us feel bad about our whole upper body. And while this is something that affects everybody, it's a mystery why until the Thanko Armpit Cooler Backpack, no one had thought to create a device that keeps those two particular spots cool, down several degrees from the environmental temperature!

The Thanko Armpit Cooler Backpack comprises two cooling units (because we have two armpits), plus a wired remote control. Each cooling unit is 44 x 90 x 41 mm (1.7 x 3.5 x 1.6"), with a Peltier cooling plate on one side and a clip with an opening of 20 mm (0.8") on the other. All you need to do is clip them onto the straps of your backpack, plug them into any USB battery or power bank with an output of 5 V and 2 A or more, and choose the cooling mode that best suits the temperature from the three available. And forget sweaty armpits for the next few hours!
