Shoulder straps are an important part of a backpack. Usually a backpack is equipped with two shoulder straps to evenly distribute the weight between the shoulders and back. Shoulder straps are often padded for comfort, especially in backpacks used for heavier loads, and they can relieve the pressure the pack puts on your shoulders.

In addition to shoulder straps, many backpacks also feature a sternum strap, which connects the shoulder straps to the chest, providing stability and preventing the straps from slipping off the shoulders during exercise. This is common in many hiking bags because the chest strap can relieve the pressure of the shoulder straps on the shoulders.

Backpack clips are used to adjust and fix the backpack body. They are fixed on the shoulder straps and can be used to adjust the length of the shoulder straps. For a detailed introduction and function of backpack clips, we have an article about backpack clips, welcome to read.

Zippers and zipper pullers are the main components of a backpack. They are installed at the closure of the backpack to ensure that the items in the backpack do not fall out.

In addition, there will also be elastic straps on the outside of the backpack to secure water bottles or jackets. They attach to the outside of the backpack for easier access and free up space in the backpack.

Exterior pockets and compartments provide quick and easy access to frequently used items, and the pockets come in a variety of sizes and configurations so you can stash frequently accessed items inside them. Some backpacks also have specialized compartments for storing specific items such as notebooks, books, and more.
