This is a Russian army cossack hat
Made from sheepskin, this tall cylinder of fur is joined at the top with a fabric circle emblem.
This hat is also known as a Papakha in Russia however there are two different styles of Papakha, this one is the Papaha, the other is the Kubanka which is a shorter version, but basically the same.
The Cossacks were an independent nation which got integrated into the Russian nation, not in a good way, so the Cossack army fought against Russia, for Russia, played both sides, helped and hindered the Germans WWII, helped and hindered the Americans in WWII, helped the British fight communism and much more.
The Cossack Army ceased to exist after World war II, however, a law was passed just before the end of 20th Century as the Soviet Union ended allowing Cossack to exist again and they now deal with local Administration.
They still wear this style of hat
