[1] A hacking jacket is a wool sports coat for casual horseback riding, often of tweed and traditionally 3 buttoned with a single vent.
[citation needed] A blazer is similar to a sports coat, typically tailored from solid color or striped fabrics.
Blazers are often made with metal buttons reflecting their origins in the British Navy and the sport of boating, though this is not necessarily a defining feature.
[2] The jacket is mentioned in the title of the 1957 rock and roll hit single "A White Sport Coat (and a Pink Carnation)" by Marty Robbins; the title was later adapted by Jimmy Buffett for his 1973 album A White Sport Coat and a Pink Crustacean.
There are several well-known manufactures such as the fifth-generation weaver Mulhern at Triona Design in the town of Ardara.
