Beat the heat with clip-on armpit fan.

It’s summer, which means the sun is shining, the temperature is rising, and armpits are sweating. While no one likes having a steady stream of perspiration dripping down the side of his or her upper body, it’s kind of hard to stop the flow when your body takes it upon itself to enact countermeasures against Japan’s hot and humid weather at this time of year.

However, Japanese gadgetry producer Thanko has a solution that’s more high-tech, and less soggy, than wedging a sponge under your arm, The company’s new Under the Armpit Cooling Device (“Waki no Shita Kura” in Japanese) is a mini fan that clips on to your shirt sleeve and delivers a blast of air to keep your pits dry.

Two AAA batteries will keep the fan blowing for five to nine hours, depending on which of the three selectable speeds you use. Alternatively, you can power the device by plugging the included 35-centimeter USB cord into your PC or a separately purchased battery pack.

The Armpit Cooling Device is priced at 1,980 yen for a single unit, or 3,800 for a set of two. The clip-on design means that in addition to attaching the device to your sleeves, you can also use it to keep you stomach or neck cool by positioning one on the front or collar of your shirt.

So thanks, Thanko, for always thinking of new ways to keep us cool in the summer.
