Stay cozy year round with the Amundsen Sports Women's Boiled Hoodie Jacket, made from 100% Merino Wool. Crafted using a technique that has been used to make clothing from mountain people and seafarers. They knit the sweater really large and then boil it down to the correct size to give you warmth and water and wind resistance. This design is finished with a Spirit of Amundsen expedition patch on the upper sleeve.
