A '''klobuk''' is an item of non-liturgical [[clergy|clerical]] clothing worn by Orthodox Christian [[monk|monastics]] and [[bishop]]s who follow the Slav traditions. It is composed of a [[kamilavka]] covered with an epanokamelavkion (veil) that are attached to each other.
Generally speaking, [[metropolitan]]s in the Slavic Churches wear white klobuks, as a sign of their rank and honor, while [[bishop]]s and [[archbishop]]s wear black ones. Also, [[metropolitan]]s and [[archbishop]]s who have been awarded this honor wear a small
jewelled cross on the front of their klobuk. This is not the case, however, in the Churches of [[Church of Serbia|Serbia]] and [[Church of Bulgaria|Bulgaria]], where [[metropolitan]]s use black klobuks, and the white klobuk with the jewelled cross is reserved for the first hierarch of the local church (but in the [[Church of Bulgaria|Bulgarian Church]], [[metropolitan]]s may also be awarded jewelled crosses for their klobuks). The practice of [[Church of Bulgaria|Bulgarian Church]] coincides with that of the [[Church of Romania]].
The [[Patriarch]] of [[Church of Russia|Moscow]] and all Rus' wears 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 in English, although this is inexact.
In Orthodox Churches following the Byzantine tradition, all monastics and [[bishop]]s, regardless of rank, wear an identical plain black kalimafi and epikalimafi (veil). The only difference between this and the
slavic klobuk is that, for the klobuk, the two component parts are attached.
