I didn't get this particular Arctic Expedition coat but I did get A546051.
It is a very well made coat and very warm. Wore it here in Chicago when it was in the teens with a wind chill in the single digits and I was warm without wearing a sweater underneath.
But it was also very heavy. I ordered an xl, my usual size in coats and it was a bit big. I wound up sending it back since I also got 2 coats from Lands End, almost as warm and almost half the price.
Sorry I can't help with your specific jacket, but I found the AE brand very well made.
You can also check AE's website but I found their prices to be higher.
