Founded in 2009 by outdoor enthusiast Zhang Kai, UTO was created to address the lack of comfortable, quick-drying, and warm sports underwear in China. Inspired by personal experience during mountaineering, UTO introduced seamless knitting technology from Italy and integrated premium functional yarns globally. The brand emphasizes strict quality control from materials to design, becoming a leading standard setter for outdoor sports underwear in China and an official supplier for 15 national ice and snow teams. UTO’s core values are comfort, freedom, and exploration, using innovative functional fabrics and craftsmanship to inspire people to embrace sports starting with comfortable base layers.
