Climate change, but also to the thermal underwear market war season. "Copper Ammo", "according to Xisi", "Modal", "Lycra" ... ... a variety of thermal underwear materials so that consumers know what to do. Recently, Miss He, working in a business unit is busy buying thermal underwear ready for the winter, but the composition of her underwear see her a little dizzy, "Lycra, copper ammonia silk, according to silk, modal ... what kind of more warm it ? "In the city's several major shopping malls, the reporters found that all kinds of famous under-name underwear have OTC: two sleeves, two legs, looked no big difference, but most of the knee parts of the pants made this year Padded handle, "is the role of knee pads," a salesman surnamed Lu said, "not in previous years, and this year, modal fabrics are very popular."
