A Klobuk is an item of clerical clothing worn by Orthodox Christian monks and bishops, especially in the Russian tradition. It is composed of a kamilavka with an epanokamelavkion permanently attached.
Slavic Metropolitans wear a klobuk that is white rather than black. Archbishops and Metropolitans usually wear a small jewelled cross on the front of their klobuk as a mark of their rank.
The Patriarchs of some Orthodox Churches (for example, the Patriarch of Moscow) wear a white klobuk that is rounded on top, decorated with embroidered images of seraphim, and surmounted with a cross. This is sometimes called a cowl.
