I found this Filson Jacket on the Dutch version of Ebay called Marktplaats.
It's a forest green Mackinaw wool jacket made for the Park Rangers of the Alaska State Park System. The 2 big chest pockets can be closed by snap buttons embossed with the Filson logo. Furthermore it has some great tin cloth details like pocket trims, elbow patches and a contrast collar. The wool is handled with a paraffin wax to keep you warm & dry when it rains or snows. The best of this buy is, it's my size!
