Because the knapsack is used in the special environment, the material and the craft of the knapsack put forward the high request. The position of all the backpack force is sewn three times with suture stitch, so that the force position is durable. Block button and other components of the backpack can be made to prevent damage, and 120 degrees Celsius deformation is not damaged. The outer material of the backpack is mainly 420D Oxford nylon, 1000D nylon, 600D or 1000Dpolyester , or 1000D Cordura. 1000D material density is high, very wear-resistant, very suitable for use in the field. Cordura is a famous high-grade wear-resistant nylon roving fabric developed by DuPont Company. The wear resistance of the material is much higher than that of the general nylon or polyester, and the weight is light. More than 90% of the world's most famous brands of backpacks use this prestigious nylon material. These materials can withstand the pressure of the 0.5m~2m and keep the objects in the package dry. Some materials also have a tear-proof function, and once punctured, the gap does not rip open and expand.
