The Devold Nansen sweater made from refined wool is a classic piece from Devold that has been popular for decades and remains just as popular today. The Nansen series is named after one of Norway's greatest explorers, Fridtjof Nansen, who was the first person to cross Greenland in 1888 wearing wool from Devold. This wool sweater has been redesigned and is a slightly lighter version of our classic sweaters. It is made from 100% pure new wool from Norwegian sheep and will keep you warm whether you are hiking in the mountains or strolling through the city.
