Can you see the split pouch at the waist. I would say that this is being used as a shot pouch, Powder horn is at his left side.

Notice the hood that is formed at the back.

Blue was the favored color. Like most textiles, capots rapidly became highly sought-after trade goods in New France. Native North Americans soon adopted the design to make their own garments from square-cut blankets, creating a kind of knee-length hooded cloak held together at the waist by a sash and closed at the chest with a clasp or pin.
