Overpacked

• To obtain a giant backpack, you need to purchase it from a Wandering Trader.

• Customization: You can recolor the backpack in any of the Vanilla and Dye Depot colors or decorate it with a sleeping bag by clicking on it with a bed or a sleeping bag from the Comforts or Upgrade Aquatic mods.

• Beautiful animations: Animations are played while walking and when opening the backpack.

• Roomy inventory: Each backpack consists of three sections: one large section with 54 slots and two smaller sections with 27 slots each (these are crafted on a workbench by placing a chest in the center and surrounding it with eight pieces of leather). All sections represents a separate inventory. 

• Balance: The backpack will start to slow you down if you fill it with too many items. The slowdown depends on the number of occupied slots: for every 27 filled slots, you lose 10% of your speed.
• Funny mechanics: You can stand on the backpack, and if you sit in a boat with a mob and then put the backpack on, the mob will be pushed out of the boat.
