cowl

The cowl (from the Latin , meaning "a hood") is an item of clothing consisting of a long, hooded garment with wide sleeves. 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.
