There is an option in the Config file to add this Backpack to the Bonus chest. It adds five upgradeable tiers that each increase in capacity as well as the number of incredibly useful upgrade slots as they go up. This Backpack can be used to craft all other Backpacks. Sophisticated Backpacks is an excellent new backpack mod that vastly improves the inventory and portable storage capabilities while you play. An Adventure Backpack cannot be inserted inside another.
Access the Backpack's GUI to mount it, then use the default key bind B to access it. Whenever a backpack is dropped, it keeps all the items stored inside, it may also be placed rendering it immune to the effects of lava.
The 2 tanks (one on each side) hold 4,000 mB of liquids each and can be manually filled with a bucket or using an Hose from which the Player can suck or spill liquids and even drink for some interesting effects. The backpack can hold 2 tools, which can easily be swapped with a tool in the hotbar ( Shift+Scrolling), the tools show on the backpack's model. It functions as a portable chest, sleeping bag, crafting table and tank and also features a quick swap tool holder. The Adventure Backpack (Standard) is an item added by Adventure Backpack mod.
