A perfect backpack for those who want more inventory space but not unlimited space. You can't have multiple backpacks on you (as most lower-quality backpacks allow), thus it doesn't invalidate shulker boxes and the need to go to the end.

Extras include pickpocketing the wandering trader (can be turned off, i turn it off) and some skins for backpack (cosmetic, can be turned off, too).

Number of rows is configurable. You want three more rows in inventory, or six? Fine. but no multiple backpacks or one-backpack-inside-another or nonsense like that.

When you get home you right-click the shelf (added by this mod) and your backpack becomes a container block which a hopper empties; meanwhile you grab a fishing backpack or a diving backpack from another shelf and do something else.

This mod just do what it says, it adds a new Backpack that can be equipped to the player Chestplate slot or in a new slot if you have the Curios API mod installed.

You can obtain skins for this Backpack, but in my opinion most of them require a lot of grinding to unlock them.
