Thanko Extreme Cooling Refrigerated Short-Sleeve Jacket 4

Can something good become better? In Japan, yes. Back in the 1970s and '80s, while the world watched in awe as Japan rose to become the second most powerful economy in the world, the concept of constant improvement or kaizen was considered one of the nation's greatest assets. And it still exists: just being good is rarely enough for Japanese manufacturers and this is why even after over 25 years of air-conditioned clothing, another like the Thanko Extreme Cooling Refrigerated Short-Sleeve Jacket 4 can appear and be much much better than pretty much everything else!

And it isn't what you can see, which is a snug, short-sleeve design and four different colors. It's what lies under the engine that makes the Thanko Extreme Cooling Refrigerated Short-Sleeve Jacket 4 so spectacular: two USB battery-powered fans at the waist, plus a Peltier cooling plate at the back, a pocket for ice packs, an exhaust fan, and the ability to bring your body temperature down by -19°C lower than the temperature around you. No matter how hot it is outside, you will always stay cool in this jacket!
