I have a Mountain Hardwear Sub Zero parka that has durable fabric and is reinforced in key areas, on sale for an astounding $124, almost 50% off. That was discontinued for the Chillwave parka that since has also been discontinued. Those were very warm and durable and they really last. I try to buy down clothing in the middle of summer when nobody wants them and the sales are outrageous.

Like Aimless my go to these days are the lightweight Montbell in both down jacket and vest. They are very well made. You are looking for something warmer but my guess is they will be expensive. Good luck with your search.
