The mozzetta is a short elbow-length vestment, a cape that covers the shoulders and is buttoned over the breast area. It is worn over the rochet or cotta as part of choir dress by some of the clergy of the Catholic Church, among them the pope, cardinals, bishops, abbots, canons and religious superiors. There used to be a small hood on the back of the mozzetta of bishops and cardinals, but this was discontinued by Pope Paul VI. The hood, however, was retained in the mozzette of certain canons and abbots, and in that of the popes, often trimmed in satin, silk or ermine material.
