cowl

A cowl is an item of clothing consisting of a long, hooded garment with wide sleeves, often worn by monks.
Originally it may have referred simply to the hooded portion of a cloak. In contemporary usage, however, it is distinguished from a cloak or cape (cappa) by the fact that it refers to an entire closed garment. Today it is worn primarily by most Catholic and Anglican monks when participating in liturgical services.
