Named for the Arctic borough that's one of the gosh-danged coldest places on the planet, this top was built to capture 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 flatlock seams eliminate chafing. Thumbholes keep sleeves in place so you can layer up without them riding up. And because Duluth women generally want it all, the highly breathable fabric wicks sweat and fights stink too. So you can warm up – without bulking up.
