Datapack Upgradable Backpack

Upgradable Backpack for Minecraft

Upgradable Backpack is a Minecraft datapack for Java Edition that adds practical storage to exploration, mining, and everyday gameplay on a Minecraft server. Its backpack can be dyed at a crafting table, renamed with an anvil, and worn in the chest slot, combining convenience with personal style. BoxToPlay makes this kind of content easy to enjoy in a shared survival world while preserving the familiar vanilla experience.

Storage expands through three stages, from 9 slots to 18 slots and finally 26 slots. When placed on the ground, the backpack becomes a barrel for managing items, then returns to backpack form through its exit control. It is a simple, useful upgrade for carrying more during every adventure.
