Run down your training goals in the Smartwool Mens Merino Sport Fleece Tight. The stretchy knit fabric puts soft-brushed Merino next to skin and durable synthetic outer material against the elements to combine comfort and protection. Featuring reflective elements for those early-morning or late-evening runs, an interior waist drawcord for a dialed-in fit, and a secure zippered pocket at the rear, these tights are the perfect addition to your winter-weather training kit.
