UYN, the new Italian brand of functional underwear, has launched its web store, addressing customers in 47 countries, with others due to follow soon. The brand, which stands for Unleash Your Nature, was launched last year by Trerè Innovation, a big Italian knitwear manufacturer that works also for Armani and Rossignol, after the loss of a production and licensing deal for X-Bionic clothing and X-Socks. The brand is sponsoring the national ski teams of Germany, France, Italy, Norway, Austria, Russia and Slovenia.
