The thieving hood is the skillcape hood associated with having achieved skill mastery in the Thieving skill. Players may buy the hood alongside the thieving cape from Martin Thwait in Rogues' Den for 99,000 coins, providing that they have level 99 Thieving, although the hood and the cape may not be purchased separately. The hood itself provides absolutely no offensive or defensive bonuses and may be worn for purely aesthetic purposes.
While the hood is bought with the skillcape, it is not needed to perform the emote associated with it; the skillcape is the only essential item. Along with the cape, the hood may be stored in the Cape rack of a player-owned house.
Should players lose the hood, they may reclaim it from Martin for free.
