These enderman have increased health (60). On very rare occasions, you may find an Enderman wearing an Ender Backpack.These backpacks can then be retrieved from the ender backpack, but cannot be put back inside. However, it is possible to get a backpack into an ender backpack by putting it in an ender chest. It isn't possible to nest backpacks (you can't put a backpack into a backpack).Alternatively, you can carry the backpack in your 'second inventory', but this will not render on your character.
This will, of course, remove your ability to wear a chest piece. They take the place of your chest piece, and they will render on your character's back as whatever color backpack you select.
