Health^ I am increasingly worried about the impact of school bags on children, especially shoulders and necks. A child with a backpack full of laptops and a few books will have more musculoskeletal pain than if they had all the personal items they need in their day-to-day life in their backpack.

　　To help with this, make sure your child is carrying no more than 5 to 10 percent of their body weight in their backpack. Leimand laptop backpack manufacturers point out that generally better backpacks have the following characteristics:

　　1. Sufficient capacity. Carrying capacity is an important consideration for backpacks. Because kids are small, capacities of 1,000 cubic inches or less are common, while backpacks for older kids start at about 1,500 cubic inches, and high school students and adults may backpack beyond the 2,000 cubic requirement. It is important that the pack can hold what may be carried.

　　2. A good backpack features good organization. While very young children may have a large box and a small pocket, older students need more organization options. Compartments to hold writing instruments, as well as notebooks and binders of varying sizes will help keep the homework down.

　　3. Sturdy zipper. A backpack is all about keeping your belongings safe and organized. Zippers should be strong and unobstructed.

　　4. A good backpack features water resistance. Your bag doesn't necessarily have to be waterproof, but some degree of water resistance should be good. Otherwise, you're all likely to get drenched if you get caught in the rain. This is especially important if you are carrying a lot of electrons.

　　5. Leimand laptop backpack manufacturers point out a good warranty. Even with good manufacturers, every once in a while your backpack should have a quality warranty, most manufacturers offer lifetime coverage for manufacturing defects, abnormal wear and tear.
