Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

🎒 Backpacks!

Backpacks! is a datapack that adds vanilla-friendly backpacks to your game! You can upgrade them and dye them!

Note- This is an edit of Gero's Backpacks nerfing the slots of the Backpacks.

Small Backpack: 3 Slots

Medium: 9 to 6 Slots

Large: 18 to 10 Slots

Huge: 40 to 14 Slots

Made to ensure Shulker boxes are a more supreme endgame way of moving stuff instead of just crafting a bunch of huge backpacks.

Permission to modify and redistribute.

Q: Can I modify the datapack and redistribute it?

A: Yes you can, but only if you say who the original creator is (Eclipse Studios) and if you link the original Modrinth page somewhere noticeable in the project.

Original creater: (Eclipse Studios)
