Traipse on across the border, Stuey and locate the nearest Army surplus Store... you can buy the same thing only much better for around $75 U.S.
I've got one that I've had since I was 18 years old... real wolf fur around the snorkle (it was available back then to the military... it doesn't frost over)... still in good condition!
Clanad, Mrs stuey ordered this coat for me. If it was left to me, I would have done something similar to what you say. Obviously you've got a lot of mileage out of that coat, and I'm sure that your winters are a little harsher than the ones where I live.
