The GUI will close, and the item you quick keyed to your hotbar will be in your hand. You can alternatively push the number of the toolbar slot your pack is in while mousing over another item. Do not move the Backpack while in use, or you will drop it.Backpacks are commonly found in dungeons and large pirate ship chests.You may have as many backpacks as you want in your inventory.This backpack comes from the Better Storage mod and can only be obtained by placing an Ender Chest next to the Frienderman, who will drop their backpack to pick up the chest. On very rare occasions, you may find a passive Enderman with 60 health (Frienderman) wearing an Ender Backpack.The backpacks inside the bag can hold bags, which hold backpacks, therefore giving infinite inventory space. You can also put a backpack into a bag, which can hold backbacks. 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.
