The single backpack shoulder strap is mostly used on cycling backpacks, travel backpacks and some other sports backpacks. This type of strap makes it relaxed and unrestrained when people backpack.
However, the flaws of the single backpack shoulder strap are also distinct. As there is only one shoulder strap, the whole weight of the backpack falls on the strap. In order to bear the weight of the backpack, the trapezius muscle exerts upward for a long time, which is more likely to cause fatigue and aches, making the shoulder with weights shrug in the long run and forming high and low shoulders.
If the daily load you bear is light, it is suitable for you to choose backpacks with single backpack shoulder straps. Otherwise, please choose backpacks with double backpack straps.

A double backpack shoulder strap is the most widely used type on backpacks currently. School backpacks, commuter backpacks, laptop backpacks and diaper backpacks all adopt such a strategy, which balances the load on both shoulders of the backpackers, thus less likely to cause damage to the muscle of the shoulders and back.

The main function of the chest strap is to adjust the opening distance of the double strap, so as to enhance the stability of the backpacks and be conducive to breathing. A hip belt, the part bearing the load of the backpack, is usually composed of a waist cushion and a belt, which is designed to be movable. The hip belt is fixed at the bottom of the backpack with Nylon stickers. After removal, it can be adjusted up and down to find the most suitable position.
