Premium Goose down! Really soft beautiful leather. This was my husband's Chicago & Wisconsin coat. We moved to Ga and no longer need it. Super warm! Extremely nice coat! Label shows Med but it would also fit Large. The zippers show signs of wear but all work perfectly. All other aspects of the coat are in perfect condition. Can be zipped from top or bottom. The hood has a drawstring that can be used to hold the hood tight around the face. Lots of pockets including side pockets to keep hands warm. They don't make them like this anymore!
