The Wolf outfit is an outfit available to purchase at Solomon's General Store. It costs 240 RuneCoins for free users and 216 RuneCoins for members. Like all other cosmetic items from Solomon's General Store, the outfit is not visible while in PvP areas.
This outfit, along with the Fox outfit and the Panda outfit, originally did not have its own premium hairstyle. Players that purchased these packs before the release of the hairstyles received them for free.
