No bag has as many different names as the backpack. Whether it is called a rucksack, knapsack, book bag, or packsack, the backpack is essentially a bag that is carried on the back of a person.

Backpacks have one strap on each side that fits over the shoulder, with the weight of the backpack is distributed over the shoulders, upper, and lower back. The straps can usually be adjusted in order to change the weight of the backpack on the back and shoulders.

The bag has one main compartment that can fit many belongings. In most cases, the backpack is secured by a zipper that runs around the bag. Sometimes, backpacks have two or three separate zipper compartments, depending on the use of the backpack. The interior of the backpack contains separate pouches and compartment for different items.

These backpacks differ from standard backpacks by being smaller, lighter, and are fastened by a drawstring or flap instead of a zipper.
