Since the default inventory in the vanilla version of Minecraft is not large enough, many players prefer to install third-party mods to expand the number of available slots for carrying resources. And here everyone faces a choice: which mod to install, what its advantages and disadvantages are, and how it differs from others. We have already reviewed many add-ons in this category (Traveler's Backpack, Sophisticated Backpacks, Useful Backpacks), among others, but recently another unique mod has appeared that offers certain advantages and functionality. You are among the first to see a review of this new add-on with all the details…


The yyzsbackpack add-on adds various types of backpacks to the game, allowing you to carry resources and significantly increase your overall inventory size. Although this is a relatively new mod released quite recently, it already offers many useful and important options — and some of these mechanics are not even present in major backpack mods we’ve reviewed before. We’ve tried to show and explain the key advantages of this add-on so you can compare it with others and decide for yourself whether it suits you or not. In any Minecraft modpack, it’s best to use only one backpack mod to avoid conflicts and crashes, so you’ll need to make a choice in favor of one option.


Additional backpacks are an essential attribute of any modded server. Even if you play in the vanilla version, there are never enough slots for carrying resources — especially when exploring dangerous biomes and dungeons where you want to bring back as much loot as possible. That’s where backpack mods come in handy, allowing you to greatly expand your storage capacity with extra slots. But each mod has its pros and cons — in terms of storage management, item transfer, and overall usability. This add-on stands out among others with several key advantages.




· Hotkeys. You can move resources using hotkeys between both inventories (player and backpack). Simply press Shift + Right Mouse Button to transfer any stack or item into additional slots;
· Automatic transfer to backpack. If your main inventory runs out of space, the system automatically transfers new resources and items into backpack slots. No need to check your inventory or rearrange items manually — this saves players a lot of time;
· Dual GUI access. When the player opens the inventory, both sections (player inventory and backpack slots) appear together. You can quickly move items between them using hotkeys in just a few seconds;
· JEI, REI, EMI support. Despite being a relatively new project, it supports all major recipe and item information systems;
· Item retention after death. If the player dies, the backpack’s contents drop as loot. You can pick them up and continue your journey;


· Different backpack types. There are many backpack variants, each crafted from different materials: leather, iron, diamond, and more. The higher the crafting tier, the more slots become available;
· Accessory support. This mod integrates perfectly with popular APIs such as Trinkets and Curios API, allowing compatibility with various accessories and additional equipment slots;
· Frequent updates. The mod is actively maintained and quickly updated for new Minecraft versions. At the time of writing, the latest version was already available for download;
· Available for multiple loaders. You can download yyzsbackpack for Fabric, NeoForge, or Forge, allowing users to build modpacks on virtually any platform.

The capabilities of this add-on are quite extensive, even though at the time of writing it had only about 5,000 downloads. Compared to major backpack mods with tens of millions of downloads, it still has great potential to gain popularity among the Minecraft community. It includes several important features missing from some large-scale mods, even if its name isn’t the most elegant. Use all the benefits of this mod, try transporting large amounts of loot, and don’t forget to configure your hotkeys for faster item management — moving any blocks, items, or resources in just a few quick actions.
