Backpack

The Backpack is a survival item that serves to expand Wilson's inventory. It costs 4 Cut Grass and 4 Twigs to craft. The Backpack itself cannot be placed in inventory and only one may be equipped at a time.

Usage
When a Backpack is created it automatically equips itself in the Chest Slot if it is available. Wearing the Backpack provides 8 additional inventory slots. This item uses the same equipment slot as Armor and Vests, which means wearing one requires sacrificing the benefits of the other.

Although Backpacks cannot be placed in inventory or in Chests, they can be placed on the ground and used for storage. Any item clicked on a Backpack which is on the ground will give the 'Store' option allowing the pack to be filled without equipping it. Backpacks do not burn, however if an uncontrolled fire (such as from a Fire Hound) is nearby they will appear to catch fire.

Trivia

 * It was added in the The Birds and the Bees & Dogs That Want to Kill You update.
 * The Krampus Sack functions like a backpack but has 10 slots.
