|“||A Large backpack that probably belonged to a hiker. Having one of these in your inventory massively increases the amount you can carry(also dependant on your Fitness skill).||”|
— In-game description
The Large Backpack is an item that offers the highest increase in a character's carrying capacity in the game. A Level 5 Fitness character can carry up to 155 lbs with the Large Backpack equipped.
When increasing a Fitness level, either by leveling up or using Health and Fitness Guides, the carrying capacity will increase by 17 lbs. This is because increasing a Fitness level adds 2 lbs to a character's personal carrying capacity, as well as the 15 lbs per level provided by the Large Backpack.
