A rubberised cotton Mackintosh is a rainproof coat or jacket that is made from a single texture, rubberised cotton. In the past, these were often made of a cotton fabric that had been impregnated with a wax, before being woven into a cloth. In modern times, this type of fabric has been replaced by newer, waterproof materials. The word Mackintosh is used mostly in the UK. These types of coats are named after the man that invented them, Charles Macintosh.
