Modular backpacks focuses entirely on one backpack and making that the best it can be.
Instead of direct upgrades, backpacks use a swappable module system that lets you build your own backpack tailored to your playstyle.
Enchantments can even change how your backpack functions entirely.

This mod is primarily designed to be an in-depth and (somewhat) balanced alternative to other backpack mods, with some more Vanilla-esque design mannerisms.

Features

Backpack

Backpack with 9 slots of storage and 4 module slots
Each module slotted shows visually on your backpack for you and others
Dye and Trim support for backpacks
Backpack dye color changes the color of its GUI
Elytras, Create Goggles, Create Backtanks, Spyglasses, and Jukeboxes are supported in module slots

8 different modules

Pouch - standard storage module
Farming Pot - allows for portable crop growth
Quiver - stores arrows and imbues them with the effects of inserted suspicious stew
Buckler - provides armor to make up for the lack of a chestplate
Sack - can store one type of item in bulk
Cooking Pot - smelts items very slowly but at no fuel cost
Echo Pouch - module equivalent of an ender chest (can hold shulker boxes, unlike other modules)
Climbing Gear - allows you to climb on and jump off of walls

(most modules have at least 1 upgrade)

4 Backpack Enchantments

Linking - worn backpack stays on death (treasure loot found in Ancient and End Cities)
Back Protection - significantly reduces damage from behind
Rationing - extra hunger you don't have room for is stored and fed back to you when out of combat
Packing - your base backpack inventory now works like a very large bundle
