The material and craftsmanship of backpacks

Because backpacks are used in special environments, high requirements are placed on the materials and craftsmanship of backpacks. All backpacks are sewn back three times with sewing thread to ensure durability and durability in the stressed areas. The buckle and other components of the backpack can be used to prevent freezing, smashing, and deformation at 120 degrees Celsius without damage. The outer materials of backpacks mainly include 420D Oxford nylon, 1000D nylon, 600D or 1000D polyester, or 1000D CORDURA materials.

The 1000D material has high density and is very wear-resistant, making it suitable for outdoor use. CORDURA is a well-known high-end wear-resistant nylon roving fabric developed by DuPont in the United States. The wear resistance of this material is much higher than that of ordinary nylon or polyester, and it is lightweight. More than 90% of famous brand backpacks in the world use this renowned nylon material. These materials can withstand water pressure of 0.5m-2m, keeping the contents of the package dry. Some materials also have anti tear function, once punctured, the tear will not tear and expand.
