Mackintosh

The Mackintosh or Macintosh (abbreviated as mac or mack) is a form of waterproof raincoat, first sold in 1824, made out of rubberised fabric. The Mackintosh is named after its Scottish inventor Charles Macintosh, though a letter k is added by many writers (this variant spelling "Mackintosh" is now standard).

Although the Mackintosh style of coat has become generic, a genuine Mackintosh coat should be made from rubberised or rubber laminated material.
