History of Parka
The parka was invented by the Inuit of the Canadian Arctic, who called it the "Amauti." Made from caribou skin and coated with fish oil, it kept them warm and dry in freezing conditions. The traditional amauti was more like what we know today as an anorak. It didn’t have an open front like the modern parkas developed since WWII.
