Swix Blizzard Warm Sweater - The Blizzard Warm Sweater M is inspired by the Norwegian cross-country skiing tradition. This sweater is made for the patient cross-country skier and is made from 100% lambswool yarn. It has a high zip turtleneck that will keep you warm on cold days. Our red Swix badge is located on the left upper sleeve, giving the garment a retro look.
