Abstract
A backpack includes a bag body, two straps, and a back casing. The straps are engaged with the bag body. The bag body has an inner surface and an outer surface opposite to the inner surface. The inner surface is adapted to face a user's body. The back casing is detachably engaged with the bag body and is located outside of the outer surface.
