Air cooled clothing is a term for clothing that actively cools down the wearer. It has primarily been used by workers in areas where air conditioning systems cannot be easily installed, such as tunnels and underground construction sites. Air-cooled clothing on the market does not operate by actually cooling down the air, as a room AC unit does. Instead, it increases the natural body cooling of the wearer by blowing air and sometimes water vapor around the body, decreasing skin temperature by the evaporation of sweat and vapor.^[1]
