Excessive supplies of books, coupled with unscientific bag design, can adversely affect growing children. Therefore, in the purchase of schoolbags, the first thing to consider is whether the backpack system is scientific and reasonable, whether it can play a role in reducing pressure and protecting the spine. Specifically, it can be viewed from three aspects:
1, the weight of the schoolbag itself. Light schoolbags can reduce children's burden.
2, is the shoulder strap of the schoolbag reasonable? The shoulder straps are wide enough to disperse the pressure on the shoulders from the weight of the schoolbag, and the straps end with a flexible air cushion.
3, a schoolbag can be better worn with a heavy waistband. This can evenly disperse the pressure caused by heavy objects and avoid excessive damage to the shoulder and back.
