One of the very good furs for the ruff around the hood (don't know the appropriate terms for your setting) is wolf, if you need to specify. It's very good at shedding moisture. The cuffs might have a different fur because it doesn't need to contend with nearby exhalations.

(Source: my mother's research when making winter clothes for my sister and me; she took inspiration from Alaskan indigenous clothing technology, because she figured they were the experts on surviving/thriving through the local winters.)

I'm pretty sure that wolves were still common in Russia at that time.
