I'm with okcmco on this one. Filson makes the best wool coats I've seen. My dad has had a double Mac for 20 years and it shows no sign of wear. He unfortunately has to buy a new one because the middle of the coat isn't expanding as fast as his middle.

I've got a Mac liner for my tin coat and it is awesome. Zip in for extra warmth, wear alone for an everyday coat and the tin coat is wonderful for when it rains or as an extra wind break.
