I would not worry about the correctness of either one I believe the earliest capotes were just repurposed blankets remodeled with sleeves and belts sewn on for convenience ,it probably wasn’t a great feat for a woodsman,settler,or native or one of thier mates to come up with one if the man had to be out in cold times hunting,trapping or fightin*,frankly,as long as there were blankets,there were capotes or the same by another name.
