Maniple (vestment)
The maniple is a liturgical vestment used primarily within the Catholic Church, and occasionally used by some Anglo-Catholic and Lutheran clergy. It is an embroidered band of silk or similar fabric that when worn hangs from the left arm. It is only used within the context of the Mass, and it is of the same liturgical colour as the other Mass vestments.
