The coat is made of genuine wool, it's the same material which is used in Finnish army wool coats. So, this wool is very warm and long-standing because army clothes are made to last. Buttons and thread are also from the Finnish army. (Buttons are with small lions ^^)
Coat has a lot of fabric (hem is extremely wide) so it is quite heavy.
Which reminds me of this :D ( These are from "Scandinavia and the World" page )
