Wolverines are native to the northern US, Canada, and the cold belt of Europe. Their soft, warm fur was very popular in the early 20th century.

​

The brown underfur is thick and dense, with the guard hair varying from dark brown to yellowish, with a white stripe along the sides. It is usually used natural and is rarely dyed, so a wolverine jacket should have dense underfur and an attractive striped pattern.

​

Wolverine fur has a durability rating of 100 so it lasts for years. But it is also heavy, so it is used primarily for trimmings, small jackets and small wraps. It is also used for the ruffs of parka hoods because it does not hold moisture and freeze against the face.
