Couriers stay cool with jackets

Shi Jiaxiang,manager of a courier station in Hangzhou, Zhejiang province, bought eight cooling jackets online for his couriers who have to work even on the hottest days of a year, when temperatures can reach 42 C in the daytime.

Through new technologies, the jackets enable cool internal temperatures at 27 C for the wearer, giving couriers a break from the hot summer air.
