Often cream in color and always chunky in texture, these timeless sweaters were first knit by the fishermen's wives using raw, unwashed and undyed wool that retained its natural oils. This provided protection from the cold, wet conditions at sea, but also made them rather stiff and smelly. Many modern versions like these are still hand-finished in Ireland using authentic patterns, but are now knit from soft, worsted wool. And if you want the heft and texture without all the weight, look for lighter cotton versions like the one from J.Crew Factory.
