Matt. I am a fan of wool. most of the guys in deer camp come out with the latest, most advance space age clothing on, and I just show up in wool. Now the other guys are starting to follow my lead and switch to natural fibers.
Anyway, the best wool coat PERIOD is the Filson Mackinaw. They make a jacket, crusier and double mackinaw. They are usually made of 24oz wool of the best quality. I think the website is www.filson.com. They will run from about 225-325 US. Expensive but will last a lifetime.
Also look at woolrich and columbia. Usually in the 80-125 range.
Do a search on ebay too. Search wool jacket and Mackinaw. I have a mackinaw that is LL bean brand but seems to be made by woolrich circa 1950's. I got it for 25 bucks. Bean and Cabelas also had stuff made by filson
