What's more unpleasant than sweating at work? The sweat that runs down your forehead, temples and then slips into your shirt collar while sitting at the computer. Not all companies have air conditioning, and some (by force or by 'vocation') do not keep it at temperatures compatible with human life. In an increasingly hot world, there is a hunt for how to make up for it by bypassing the air conditioner.
Some choose huge fans in the room, while others choose small ones to place right on their shoulders. The disadvantage of these fans is that they direct the air directly to the face and are not very attractive. Think about a telecommuting videoconference where you would see yourself with a fan in front of the camera? I don't see it feasible. This new concept of “shirt” air conditioner invented by Kevin Von it could represent a turning point.

How is this shirt conditioner made?
When it comes to keeping cool while walking around town, very light and sporty clothing is the best there is. Just the kind of clothes that are seen worse in the workplace, by the way. It is not easy to reconcile current technology with the sobriety of clothing: we have already talked about some "personal" air conditioners such as the Reon Pocket by Sony. The Japanese contraption works and is sold, but it costs around € 100, requires special t-shirts (at € 20 each) and does not yet have the air of a product that could win over a large audience.
This Portable Fan II invented by Kevin Von and instead a small 3D printed object that slips into the collar of your shirt and brings freshness from the base of the neck towards the face. Fresh air comes blown all around your head and no longer directly on the face. It works (guess what?) Thanks to a companion app on your smartphone that allows you to choose the temperature, and to regulate the power of the expelled air. Beautiful, is not it? Or not?
I have the impression that you are not yet persuaded to buy a personal air conditioner. I can't blame you, everything still feels so embryonic to me, and this "shirt" fan is no exception.
Do we have alternative remedies?
If you don't like these little “not always necessary” gadgets, here are some ideas to keep your room cool without relying on technology. S.and work remotely, choose a location north of your house: place yourself as far as possible from the window and equip it with blinds or blackout curtains. Avoid over-lighting the room (small LED desk lamps are enough). If it's really hot, place a frozen bottle of water in front of the fan blades (not pointed at you): sometimes having a future is also a matter of practical traditions :)
