A crew neck (or crew-neck) is a type of shirt or sweater that has a round neckline and no collar, often worn with other layers.[1][2] The T-shirt crew neck was developed in 1932 as an undergarment that would absorb sweat and prevent shoulder pads of American football players from causing chafing.[3] The U.S. Navy was the first of the U.S. armed forces to adopt the crew-neck T-shirt or "Gob Shirt."[3]
