poncho

n. cloak that resembles a blanket with a hole in the middle for the head

A poncho is a simple garment designed to keep the body warm, or if made from an impermeable material, to keep dry during rain. It is essentially a single large sheet of fabric with an opening for the head and sometimes for the arms. Some ponchos, especially those made to ward off rain, also have hoods attached.
