During the middle ages, wolfs were exterminated by law in most of Europe because they would destroy farms crops and livestock. This meant that their pelts were a dime a dozen and so a few landed on peoples back as clothes.
As to why it was used by archers, I have never read such a thing anywhere but in my personal opinion I highly doubt that archers would prefer wolf pelt because pelts are less flexible than materials like leather and to an archer flexibility and speed is very important.
