If you’re looking to complement your air-conditioned shirt with a pair of pants to help keep your bottom half cool in the summer heat then Japanese company Kuchofuku has you covered. The Kuchofuku Air-Conditioned Cooling pants feature two battery-powered fans to direct a refreshing flow of air onto your legs and nether regions.
The cooling hardware hangs in dedicated pockets sewn into the outer thigh of the pants and is lightweight enough to not burden the wearer too much. The pants are made from a 65 percent polyester, 35 percent cotton blend and are available in M, L, 2L and XL sizes, to fit waists from 108 to 129 cm (42.5 to 50.8 inches). Color choices are somewhat limited with only a light khaki green available.
The pants join Kuchofuku’s range of air-conditioned products, which includes the aforementioned shirts, jackets, helmet, cushions and even a bed.
Air-conditioned lower limbs don’t come cheap, however, with the fan-cooled trousers priced at US$206 through Japan Trend Shop.

I dont think that short sleeved shirts and shorts are a viable alternative as they both expose you to the sun which may be undesired, aswell being exposed to the air doesnt mean that the air will be circulating on your skin very much. Having fan propelled air will cool the skin faster then being just exposed to your environment, aswell as not needing suntan lotion. I could also see this being good for people who have sweating problems as circulating air helps quite abit, and that is a fairly good segment of the population who has hyper hydrosis.
This isn't quite what we usually tend to think of as "air conditioned" these days at least in north america, but technically the name fits.
