Be colorful, comfortable, and confident in Smartwool's Women's Merino Sport Fleece Colorblock Tight. This women's base layer uses a stretchy knit fabric that puts soft-brushed Merino wool next to skin and a durable synthetic material against the elements to balance comfort and weather protection. An interior waist drawcord allows for an adjustable fit and reflective elements aid in visibility in low light conditions-so you can adventure at any time of day or night without worry.
