D2 Hat/Cap New Era 39Thirty Made in Vietnam Adult M-L Stretch AFL patch in RWB on face and rear and New Era Logo on side in white/Black 95/5 Poly/Spandex. The American Football League (AFL) was a major professional American football league that operated for ten seasons from 1960 until 1970, when it merged with the older National Football League (NFL), and became the American Football Conference. The upstart AFL operated in direct competition with the more established NFL throughout its existence. It was more successful than earlier rivals to the NFL with the same name, the 1926, 1936 and 1940 leagues, and the later All-America Football Conference (which existed between 1944 and 1950 but only played between 1946 and 1949).
