Backpacked is a simple inventory mod that clears up 9 slots of storage. It gives just that little bit more space that you could need and blends well in the Minecraft aesthetic. Plus it can make good use of leather if you don’t have much need for it.
The great thing about this mod is it doesn’t take up any additional slots on its own and it sits right on your back. All you need to do to access it is tap B and the GUI opens up.
And the backpack will stay with you upon death too so it can function as an extra security measure for precious and rare items.
