I have tried on the Barents Parka before. They run large. I am 5'11 250lbs and I can ALMOST squeeze into a Large, where I have to wear xl or xxl in other jackets.
I can't compare the filling to down, but they were very heavy and warm when tried in the store here in Stockholm. The build quality felt superb.
Also note that they are a Parka cut and are longer than how it is represented in the photos, as they have it tucked near the waist of the model. The Large on me covered my hips and rear, as it is a winter coat and it helps to keep your hips warm as well.

Here is the length from the back.
