Shoulder type
The backpack is a general term for the backpacks that are carried on both shoulders. The most obvious feature of this kind of backpack is that there are two straps on the back that are used to buckle on the shoulders. It is generally used widely among students. It can be divided into canvas bag, oxford bag and nylon bag according to different materials. The main advantage of the backpack is that it is easy to carry, free hands, and convenient for going out.
The grade and quality of backpacks are mainly determined from several aspects.
First, workmanship. Every corner and pressing line are neat, without thread off and jumping. Every stitch of embroidery is exquisite, which is the standard of high technology.
Second, the materials for backpacks. Generally, 1680D double ply fabric is medium, while 600D oxford fabric is commonly used. In addition, materials such as canvas, 190T and 210 are usually used for backpacks with relatively simple bundle pockets.
Third, the back structure of the backpack directly determines the use and grade of the backpack. The back structure of high-grade and outdoor mountaineering or military backpacks is relatively complex, with at least six pieces of pearl cotton or EVA as the breathable pads, and even aluminum frames. The back of an ordinary backpack is a 3MM piece of pearl cotton as a breathable plate. The simplest bundle pocket type backpack has no padding material other than the material of the backpack itself.
To sum up, backpacks are mainly the best choice for leisure and going out. The backpacks of different grades are suitable for different occasions and will not be described here.
