The Mackintosh or raincoat (abbreviated as mac) is a form of waterproof raincoat, first sold in 1824, made of rubberised fabric.
The Mackintosh is named after its Scottish inventor Charles Macintosh, although many writers added a letter k. The variant spelling of “Mackintosh” is now standard.
Although the Mackintosh coat style has become generic, a genuine Mackintosh coat is made from rubberised or rubber laminated material.
