A warrior's wolf tail is a hairstyle worn by male Water Tribe warriors. The wolf tail differs from a top-knot in that it is simply hair pulled back tightly and tied behind the crown of the head, rather than being tightly curled into a knot on top of the scalp. Since both styles are so similar, Sokka was able to make only minor alterations to his hairstyle to blend in with citizens of the Fire Nation during Team Avatar's travels there.
