Do you remember the facekini? It's a mask designed for swimmers to prevent sunburn and jellyfish stings? /Tencent Photo

Recently, the facekini has been upgraded. The creator, Zhang Shifan from Qingdao, Shandong Province, has launched a line of facekinis for the winter. /Tencent Photo

The knitting is made from wool. Holes are cut for eyes, nostrils and the mouth, which is similar to the summer facekini. However, there are some tassels, which look like a mustache over the mouth and nostrils. /Tencent Photo

Zhang said the design can help prevent people from breathing in too much cold. The knit facekini is now priced at 70 yuan (11 US dollars). /Tencent Photo

Zhang debuted her design in 2004, and there are now seven versions of the facekini. Each year, Zhang sells up to 40,000 units. /Tencent Photo
