Named for the Arctic borough that's one of the gosh-danged coldest places on the planet, the Noorvik Quarter Zip Base Layer Top has 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 offset flat-lock stitching reduces bulk and chafing at the seams. What we're trying to say is: Warm up, without bulking up. While you're at it, zip it up! Or don't. Your neck, your business.
