The Tyrolean hat (also Bavarian hat) is a type of fedora hat named for the Tyrol in the Alps. It is essentially the shape known as the Trilby. Tyrolean hats are made of felt, traditionally having a corded hatband and a feather on the side as trim.
The traditional "brush" worn on the hat is made of the tail of the chamois goat. The brush takes a variety of forms, and may often be combined with feathers.[1]
