I expected the felt lining of my Great Northern Choppers to be somewhat heavier, however, coupled with a pair of your wool liners they are quite comfortable. Although I usually wear a large, I took your fitting advise and purchased your medium size. They fit just right. Even with the liners they are comfortably roomy. Their material and construction present a quality product that I know will provide warm and dependable service for years to come.
I expect Daniel Greysolon du Lhut, the 16th century Quebec fur trader/coureur for whom your City of Duluth is named, would have delighted at the opportunity to trade you a few pelts for a fine pair of your Great Northern Choppers...let alone your whole catalogue of traditional high-quality outdoor adventure goods. From design to material and craftmanship, he would agree you folks do it right.
All the best from Ontario
