The ADV Essence Wind Tights are a sophisticated and highly functional garment designed for intense training in cold and windy weather. It's made from a soft jersey knit with a brushed interior for warmth and comfort, and features a windproof panel at the front that protects from gusts. The drawstring waist ensures a snug fit while the zippered rear pocket lets you store items securely. The ADV Essence Warm tights are made from recycled polyester fibers. In addition to being environmentally friendly, recycled polyester wicks moisture very well thanks to its excellent breathability.lité.
