UTO was established in 2009 by founder Zhang Kai, an outdoor sports enthusiast specializing in mountaineering and skiing. Motivated by the discomfort and issues experienced with existing outdoor sportswear during a snow mountain expedition, Zhang aimed to create sportswear that is close-fitting, quick-drying, and warm. UTO introduced and improved Italian seamless knitting technology and integrated high-quality functional yarns globally. Every detail from materials to craftsmanship and design is strictly controlled to ensure quality. UTO has become a leading standard setter for outdoor sports underwear in China and a supplier for 15 national ice and snow teams. The brand embodies comfort, freedom, and exploration, using technological functional fabrics and meticulous design to inspire more people to love sports starting from comfortable base layers.
