Why using adfocus?

Some of you may find it annoying to wait 5 seconds before downloading the content, but please remember that the time used to develop the content has been much longer, and the download still is 100% free and safe,
unlike other creators who sell even the simplest of their content.
Please appreciate my effort in trying to earn a few cents after hours and hours of work over the past years in the fairest and best way for everyone.

1.17-1.20 Version : HERE

Backpacks Datapack (1.17+)
The first datapack [​2020] adding aesthetically pleasing datapacks, actually working and visible on the player model when held, without mods and in a multiplayer friendly-way.

Backpacks can contain items, up to 27 slots!
The backpack recipe is simple, and with the classic model come its coloured version.

Just download the datapack and its needed resource pack

(for servers, it can be renamed resources.zip and put in the world folder)

and try it. For additional info consult the official WIKI of the pack or ask in the comments of this PMC page.

I hope you'll like this wonderful datapack, let me know for any suggestion, needed bugfixes or anything else! As always, working for free, working for you! Feel free to help with a diamond and subscription.

Major Update - now 1.21 : by UltroGhast 06/26/2024 10:15:05 amJun 26th

> Now working on 1.21
> Code and logic rewritten
> Backpacks from previous versions will automatically get "mouldy"
> You can now no longer put shulker boxes or bundles inside backpack
> You can now close the backpack directly by passing it from second hand to main hand
> Craftings do not show a knowledge book anymore, looking more vanilla
> You can now color backpacks by benching it on a crafting table and then clicking it with a dye.
> You can now obtain benched backpacks just by clicking on them.
> Rainbow backpack texture changed (still wip)

Where can I find the previous versions?
How can I "bench" a backpack?
Just drop it on a crafting table / loom / cartography table, check HERE
My old backpack is now mouldy, how do I update it to 1.21?
You'll need to bench it first, then hit it with a mace (the new hammer item).
see how HERE

It doesn't seem to show up on my back for the 1.21 version. its a new backpack, I've downloaded the datapack to the server I run, and I've loaded the resource pack to my client, it looks like I'm holding it in my hand at my side and not my back. Do you know what's happening?
Thanks in advance!

It's just happening that you are not holding it in your off hand.
Pls read the datapack info and wiki before asking questions.

Just installed it, works great in 1.21! Thanks for doing this, I've missed it so much!

It is very worth mentioning that Backpacks made from an older version of this datapack will not work now and you will get the error "ulg.alert.oldversionbackpack". I thought it was the pack at first but quickly realized that I just needed to delete the old pack and make a new one.

Good day UG! Unfortunately I don't seem to be able to get this to work either.

I have created fresh 1.20.6 and 1.20.5 worlds with this as the only datapack. In both versions the pack does list as enabled-


I have also restarted each world to see if that would help but it doesn't, the recipe doesn't seem to generate an book of knowledge.

Hope this helps a bit, good luck!

Do your best, we are all just here to have "fun". I can honestly say, though, that I don't feel the same level of enthusiasm I used to when updating my texture pack, it's getting a little bit grindy. Look at the latest snapshot- 10 new paintings? Whose wish list was that on? Anyway, no pressure my friend. Definitely prioritize this as you are able, we all have busy lives when we are not doing this ; )
