Cagoule

A cagoule (French: [kaɡul], also spelled cagoul, kagoule or kagool), is the British English term for a lightweight weatherproof raincoat or anorak with a hood (usually without lining), which often comes in knee-length form.

In some versions, when rolled up, the hood or cross-chest front pocket doubles as a bag into which the shell can be packed.

A cagoule which could be rolled up into a very compact package and carried in a bag or pocket was patented[2] by former Royal Marine Noel Bibby and launched in the UK under the brand name Peter Storm in the early 1960s.

[2] Original versions were lightweight and packable with generally an integral hood, elastic or drawstring cuffs, and a fastening at the neck.

Later copied and marketed as a close-fitting cheap fashion accessory, the style became very popular in the United Kingdom during the 1970s.
