With summers getting hotter every year, keeping your armpits dry is quite the challenge. While many of use still rely on deodorants², the quirky Japanese have come up with a high-tech³ alternative worthy⁴ of their reputation for crazy inventions – clip-on armpit fans.

 

如今夏天一年比一年热，要保持腋窝干爽是个相当大的挑战。许多人还在依赖除臭剂，另类的日本人已经想出了一种高科技替代品，一个名副其实的疯狂发明——夹在腋下的风扇。
 

 

Developed by Japanese gadget⁵ maker⁶ Thanko, the Waki no Shita Kura (Japanese for Under the Armpit Cooling Device) is a small fan that clips to your sleeve to deliver cooling blasts of air to your armpits.

 

The device is powered by three AAA batteries and can keep your armpits nice and dry for five to nine hours, depending on which of the three speeds you use. If you want to stay cool for longer you can connect the fan to your PC or a separately purchased battery pack with the included micro USB cable.

 

Thanko claims the armpit fans are very light (30g/1 oz) and silent enough to use even in a crowded, so you shouldn't have to worry about attracting unwanted attention with your buzzing armpits.

 

The fan is also very small (60 x 65 x 15mm) and thanks to the clip-on design it can also cool your chest area: just clip it to the front of your shirt and it will keep your torso and neck dry.

 

Japan Trend Shop has the Thanko Under the Armpit Cooling Device priced at $24, but you'll probably need to buy two of them, unless you're planning on alternatively using it on your armpits. So $48 on a device that probably works. I'd say deodorant¹ is the safer and cheaper choice, but then again this thing is worth it just for the novelty of it.
