Bag, also known as backpack, is a clothing item used to give extra inventory space for players. It is one of the most common clothing items obtained by players, as this does not take any inventory space, and is wearable with any type of clothing. It is automatically used when crafted.
The bag was released on the Look Cool update, along with helmets, paper, and the IKEA Manual. Currently, wearing the backpack gives the player five inventory slots, allowing for fourteen inventory spaces in total.
The bag becomes a necessity in late game, as players have to obtain different resources for advanced recipes.
The player can only have one bag at a time. When wearing a bag, players cannot craft bags. The bag can be crafted with 6 thread and 5 wolf fur near a workbench. The bag can be worn with any form of headgear.
