means A heavy hooded jacket, usually insulated and lined with fur or fleece, built to keep you warm in brutal cold.

from The word comes from Nenets, a language of the Arctic Samoyedic peoples of northern Russia, where it named a skin coat. It traveled into Russian and then into English by way of the Aleut people of Alaska, who used the word for a similar fur garment. Fittingly, the word itself made the same journey as the coat: born in the far north, worn against the killing cold.
