Exposed to relentless sun and wind, the Nankoweap Trail turns surprisingly cool once the sun disappears. These bottoms will keep you dry and protected during the day and warm at night. Worn alone, they provide 50+ UPF sun protection and a cool, drying airflow. Paired with another layer, they wick moisture and add warmth when temperatures drop. Made with our stretchiest Capilene performance baselayer fabric for breathability, exceptional stretch and ultra-fast dry times. With a wide, self-fabric mesh-lined waistband for next-to-skin comfort, offset side seams and a gusseted crotch for mobility. Made of 4.6-oz 94% polyester/6% spandex jersey, with Polygiene permanent odor control. Fabric is bluesign approved.
