A boilersuit (or boiler suit), also known as coveralls, is a loose fitting garment covering the whole body except for the head, hands and feet. Terminology The term boilersuit is most common in the UK, where the 1989 edition of the Oxford English Dictionary lists the word as having been first used on 28 October 1928 in the Sunday Express newspaper. The garments are typically known as coveralls in North America, while overall(s) is used elsewhere. In North America "overall" is more usually understood as a bib-and-brace overall, which is a type of trousers with attached suspenders. A more tight-fitting garment that is otherwise similar to a boilersuit is usually called a jumpsuit. The "siren suit" favoured by Winston Churchill (but also worn by many others in the UK when air raids were a threat) during the Second World War was closely similar to a boilersuit. Description A boilersuit is a one-piece garment with full-length sleeves and legs like a jumpsuit, but usually less tight-fitting. Its main feature is that it has no gap between jacket and trousers or between lapels, and no loose jacket tails. It often has a long thin pocket down the outside of the right thigh to hold long tools. It usually has a front fastening extending the whole length of the front of the body up to the throat, with no lapels. It may be fastened with buttons, a zip, velcro, or snap fasteners. Boilersuits with an attached hood are available. The word "boilersuit" may also refer to disposable garments such as DuPont's Tyvek suits. Usage Coveralls are most often worn as protective clothing over "street" clothes at work. They can be used for painting and decorating, mechanical work, farming, factory work, and other activities where clothes may become soiled. Many companies provide workers with corporate branded boilersuits for identification and marketing. Coveralls are also sometimes used as prison uniforms in the U.S and other countries. SWAT units often use boilersuits as a uniform, for instance the French police unit Compagnies Républicaines de Sécurité, and the Austrian units EKO Cobra and WEGA. Similar coveralls made of Nomex in olive drab (and more recently, desert tan) are also used by the crews of armoured fighting vehicles in the US Army and Marine Corps, where the men and also their suits are sometimes called "CVCs", an abbreviation of "Combat Vehicle Crewman".
