A helmet is an item/armor in Minecraft used to protect a player's head area from damage. Like swords, they come in different materials: leather, iron, gold, and diamond. A helmet made of chainmail is also available in-game, but cannot be crafted, and can only be obtained via trading or as a rare mob drop if the mob itself is wearing the armor.
