Seamen around the North Sea face harsh weather -- cold, wet and windy. In Norway, as in Britain and France, they depend on wool garments to keep warm. Devold produces the premier seaman's sweater in Norway, the traditional blue sweater of the North Sea, worn as an outer garment during moderate weather or under an oilskin during harsh conditions. It has an extremely tight knit with a fine worsted yarn, to provide good protection against wind and rain. It has a flat surface, including hemmed cuffs and waist, to counter snagging under work conditions, and hard use tends to polish the surface rather than abrade it. This zippered turtle neck is a great choice for outdoor use in changeable weather, for work requiring warmth without bulk, or just when you want a sweater with the classic qualities derived from a long work tradition. Back length of a size L [42] is 28-1/2 inches, weight is about 1 lb., 14 oz.. Pure new wool. Hand washable. Made in Norway by Devold.
