As long as you can find Polaris in the night sky, you can navigate your way back home and walk through the door in time for supper. And while the Swix Polaris Long-Sleeve Top won't actually hold your hand and trace the distance between Ursa Major and the North Star, it will help insulate you from the cold as you try to orient yourself amidst all those shiny orbs of burning gas. Built with the cross country skier in mind, the Polaris is a warm, highly breathable, sweat-wicking mid-layer that includes stretch panels on the sides and underarms for an athletic feel. The panels also help shed excess body heat and regulate your core temperature.
