Overpacked Mod adds giant travel backpacks to your game. This mod gives you a large storage space equal to four regular chests. You can carry all your loot without running out of room during long trips. The backpack has three separate sections to help you sort your items. If you put too many heavy things inside, your walking speed slows down. You can buy this huge bag from a Wandering Trader instead of crafting it.
