Minecraft wiki entry for Zombie, associated text: Armor worn by zombies is not damaged from most damage sources, which means it cannot "wear out" the way player armor does. Helmets (not blocks like pumpkins) on zombies can eventually wear away and break if the zombie is exposed to daylight or has an anvil or other falling block dropped on its head. Zombies also have a natural armor rating of 2 (), giving 1.6 - 8%‌[JE only]/8%‌[BE only] damage reduction from most sources. Zombies can also wear mob heads, although they need to be dropped by the player before the zombie can pick one up and put it on.
