How can a China laptop backpack be extra durable

1. The outer material of China laptop backpack:
The microfiber material that is very close to the real leather is preferred, and the strength and lifespan are very good;
High-strength 65D Oxford cloth, effectively waterproof;
2. Easy to use smooth zipper (do not choose all copper zipper!)
3. High quality fasteners.

4. Inner material
Most of the inner material of China laptop backpack is polyester fiber, which has high strength and resistance to dirt and wear. It refuses to use any chemical fiber gauze or cotton lining, which is easy to break and extremely easy to get dirty.
5. Ergonomics
Many China laptop backpack manufacturers especially like to mention ergonomics. In fact, the key to China laptop backpacks is the S straps that prevent shoulders from falling off and the back cushioning sponge design, both of which can improve comfort, increase cushioning and ventilation, and reduce clothing wear.
6. Workmanship quality inspection
Basically, most China laptop backpacks have undergone a relatively complete quality inspection. There are several main stress parts, one is whether the line at the lifting position is stable, and the other is the zipper interface.
