A cagoule is a thin coat with a hood that stops rain from getting you wet. It is light, often made of nylon or a shiny cloth, and you can usually roll it small and push it into a bag. It will keep rain off; it will not keep you warm like a winter coat. This is mainly a British word. American speakers more often say rain jacket or raincoat, and even in Britain a lot of people now just say rain jacket. Though actually, the French word it comes from was not a jacket at all — it was a hood that covers the head, the kind a monk might wear, or even a hood that hides the face. English took the word and, over time, used it for the whole thin pull-on coat. Some older British speakers still picture that slightly sad 1970s nylon cagoule you yank over your head when the sky breaks. Also spelled kagoule. You say it roughly kuh-GOOL.
