These cool- to cold-weather running tights are warm at the start of your run, then wick moisture when body heat rises. A recycled nylon and polyester blend with a microterry back side provided soft, next-to-skin comfort while also allowing for increased wicking during high output. Waistband has internal flat elastic for comfort and drawcord for an adjustable fit. A gusseted construction provides good range of motion. Secure zipper pocket at center back and reflective logo.
