With the continuous improvement of people's living and consumption level, customized high-quality backpacks have gradually become a development trend. The customized backpack is not only more practical, but also can achieve the publicity effect for enterprises. How to judge the grade and quality of customized backpacks?

First, work. Every corner and thread pressing is neat, without thread off and jumper. Every stitch of embroidery is exquisite, which is the standard of high technology.

Second, the materials for customized backpacks are generally 1680D double-ply fabric, which is relatively medium, while 600D oxford cloth is generally used. In addition, materials such as canvas, 190T and 210 are usually used for backpacks of simple bag type.

Thirdly, the back structure of the customized backpack directly determines the use and grade of the backpack. For high-end and outdoor mountaineering or military backpacks, the back structure is relatively complex, with at least six pieces of pearl cotton or EVA as breathable pads, and even aluminum frame. The back of the general backpack is a 3MM pearl cotton breathable board. The simplest backpack type has no padding material except the backpack itself.
