With Japan's summer being what it is (i.e. unbearably humid), it's no wonder that designers have been exploring the idea of "portable air-conditioning": systems you can carry around to keep you cool while working in the summer heat. This Tajima Seiryo Jacket Cooling System is one such example, but what makes it stand out from the rest is its flexibility: it can fit under almost any shirt or jacket!

The heart of the system is a powerful, three-speed fan, and a sturdy yet flexible silicone funnel, which, combined with a hinge, follows the contours and movements of your body. You just clip it on the back of your belt, slide it beneath your shirt or jacket, and fire it on, and then its rechargeable battery will give you between 6 and 8.5 hours of cool. This device will guarantee that sweat will dry up as it comes out of your skin, rather than clinging to your clothes for hours on end. The Tajima Seiryo Jacket Cooling System is the best solution for working in a sweat-free environment regardless of the temperature outside!
