Amid the recent hot weather, Zhejiang Yisijia Outdoor Equipment Technology Co., Ltd. has launched a cooling vest that can lower body temperature by 8 to 15 degrees Celsius. The vest features two cooling modules and two fans on the back; the fans draw in outside air, which is then cooled by the modules and circulated inside the garment to deliver a cooling sensation.
Equipped with a 20,000mAh power bank, the vest offers three adjustable levels and a battery life of up to 12 hours on the low setting. The company developed the product in collaboration with universities and colleges in March this year. It is now available at the company’s factory store and sells well in overseas markets such as Dubai, Saudi Arabia, Japan and South Korea.
