Backpack

Backpacks are used by survivors in The Last of Us and The Last of Us Part II to carry their equipment. They are also used in Factions MP by any character the player controls. The player can have Joel, Ellie, and Abby collect and carry a variety of things throughout the game such as:

• Crafting materials (i.e., binding, rags, alcohol, explosive, and sugar)
• Collectible items (i.e., artifacts, comics, training manuals, and Firefly pendants)
• Upgrade materials (i.e., parts and supplements)
• Crafted Items (i.e., health kits, nail bombs, Molotov cocktails, smoke bombs, shivs, and upgraded Melee weapons)
• Any other weapons (i.e. guns and melee Weapons). Melee weapons are carried on the side of the backpack and guns are either in the backpack or in holsters)
• Other throwable objectss (i.e., bricks and bottles)

Skins

Although Joel and Ellie use the same backpacks throughout the entire first game, there are several backpack skins that the player can unlock. These skins can only be unlocked after the player has beaten the game. For Joel, there is the Camper Backpack and the Military Backpack. And for Ellie, there is the Daxter Backpack and the Punk Backpack.

Trivia

• There are moments in the The Last of Us when Joel and Ellie won't have their backpacks available and must make do without their inventory. For example, when Joel and Ellie are yanked out of their truck by hunters Joel must first kill both of them before retrieving their backpacks. 
• When accessing his backpack, Joel will sometimes tell Ellie to cover him as he is vulnerable while doing this. Also, Ellie will sometimes urge him to hurry up.
• In Santa Barbara, Abby wears the backpack used by Owen Moore in Jackson, after having lost her old one on the Seraphite island.
