For many, fanny packs were one of the worst aspects of the 1980s that should be consigned to oblivion. From a fashion standpoint, that might well be right, but let's be honest: they certainly were practical. And the Logos Wearable Cooling Unit takes that practicality to the next level by making the fanny pack into a portable cooler that can keep you cool for up to 58 hours using a standard USB mobile battery like the one you would use for your cellphone.
Available in two sizes, adjustable for different waists, and light enough even for children to carry or use, the Logos Wearable Cooling Unit doesn't require any special clothing: just let your regular T-shirt fall over it and the fan delivers a stream of cool air at three power settings depending on your needs. Plug in any regular mobile battery (5 V, 1/1.5/2/2.1 A), put it in the fanny pack, and you're good to go: not fashionable but cool in the most literal sense
