Named for the Arctic borough that's one of the gosh-danged coldest places on the planet, the Noorvik Quarter Zip Base Layer Leggings have been engineered to capture your body heat and hold it close. The hearty, extra-lofty 6.2-oz. 92% polyester/8% spandex fleece has knit-in channels for more warmth, less bulk, while flat-lock seams eliminate chafing. The elastic waistband is built for ahhh-some comfort and stay-put-ability.
