This kind of garment, originally made from caribou or seal was invented by the Caribou Inuit, Inuit (Eskimo) of the Arctic region, who needed clothing that would protect them from wind chill and wet while hunting and kayaking. The word anorak comes from the Kalaallisut word anoraq, while the word parka is of Aleut origin. Certain types of Inuit anoraks have to be regularly coated with fish oil to keep their water resistance.
The words anorak and parka are now often used interchangeably, but when first introduced, they described somewhat different garments, and the distinction is still maintained by some. Strictly speaking, an anorak is a waterproof jacket with a hood and drawstrings at the waist and cuffs, and a parka is a knee-length cold-weather jacket or coat; typically stuffed with down or very warm synthetic fiber, and with a fur-lined hood. Originally an anorak specifically implied a pull-over jacket without a zipper, button or frogged opening, but this distinction is now largely lost, and many garments with a full-length front opening are now described as anoraks.
