Zone (vestment) - Definition

The Zone is a liturgical belt worn as a vestment by priests and bishops of the Eastern Orthodox Church. It is made of brocade with an embroidered or appliquéd cross in the center, with long ribbons at the ends for tying around the waist. It is worn over the sticharion and the epitrachelion and keeps them in place as the priest performs the Divine Liturgy.

The zone is not worn for services when the priest is not fully vested, e.g. vespers or matins.
