Jackets with built-in electric fans are proving a hit in Japan during the country’s record-breaking summer.

The prototype grey nylon coats have two fans in the back above the waist which are connected to a battery pack.



They resemble a puffy down jacket when the fans are switched on to draw air in, reports The Straits Times website.



Despite their odd appearance, the jackets – which cost 9,900 yen (£87) – are proving very popular following a record run of high temperatures.



The air runs along the wearer’s body and comes out at the cuffs and the neckline, drying off sweat which cools the skin as it evaporates.
