The Miner's Tunic is part of the Miner's Armor set, added by the More Armor idea pack. It is one out of the three components of the set that has its own ability, the others being the Miner's Helmet and Miner's Boots. There are no leggings.
The Miner's Tunic provides a natural protection level the same as that of Leather Armor.
When the player's inventory is opened, the Miner's Tunic will open a special "compartment" to the side. Pickaxes, Swords, Shovels, anything obtained from ores and food can be placed in it. This allows the player to carry spare tools without clogging up their inventory.
