How to judge the grade and quality of a backpack?

With the continuous improvement of people's living and consumption levels, customized high-quality backpacks have gradually become a development trend. Custom backpacks are not only more practical, but also effective for businesses. How to judge the grade and quality of a backpack with a custom backpack?

First, workmanship. Every corner and crimping is very neat, there is no thread disconnection and jumper phenomenon, and every needle embroidery is very exquisite, which is the standard of high craftsmanship.

Second, the material used for customized backpacks, generally using 1680D double-stranded fabric is relatively medium, while 600D Oxford cloth is a more commonly used material. In addition, materials such as canvas, 190T and 210 are usually used for simpler bundle pocket type backpacks.

Third, the back structure of the custom backpack directly determines the use and grade of the backpack. High-grade and outdoor mountaineering or military backpacks, the structure of the back is more complicated, at least more than six pieces of pearl cotton or EVA for breathable cushions, and even aluminum frames. The back of the general backpack is a piece of about 3mm pearl cotton as a breathable board, and the simplest bundle pocket type backpack does not have any padding material except for the material of the backpack itself.
