Thank you. I don't really remember what kind of fabric the cape is. I just went at a store where they sell fabrics, and I looked for a matte black type of cloth that would contrast the rest of the leathery suit. So I don't know what it's called, but it is a synthetic fabric, that kind of feels almost furry on the outside (with extremely short fur, like on the body of a cow or a horse), and on the inside it just feels like standard drape-like fabric. I'm sorry I cant' be more helpful than that.
