Testing standards:

China: GB/T2912, GB/T17592, GB19942, GB/T7573, QB/T1333, QB/T1332, QB/T2155;

Five factors to identify the quality of a backpack. The quality of a large-capacity backpack should be inspected from five aspects:

1. Materials used: Generally, 300D to 600D Oxford cloth is used, but the texture, wear resistance, color, and coating will be different. Generally, European and American products are better than Japanese products, Japanese products are better than Korean products, and Korean products are better than domestic ones (this is not to belittle oneself, This is actually the state of the industry, especially functional fabrics). The best fabric is DuPont CORDURA, which is strong, wear-resistant and has performance that exceeds other fibers.

2. Design: bag shape, carrying system, space allocation, small bag configuration, external plug-in design, back heat dissipation and perspiration, rain cover, etc. Good backpacks have outstanding advantages in design.

3. Accessories: Zippers, fasteners, closing ropes, and nylon straps are all very particular. The most popular good zippers are Japanese YKK zippers, which are divided into original and domestic ones. The best zippers are produced in Northern Europe. There are many quality levels of fasteners.

4. Technology: The level of processing technology is determined by worker skills and machine equipment, such as multi-functional double-needle machines, knotting machines, one-time molding compression molding machines, glue presses, etc. Program design and quality monitoring also play an important role. Visiting some backpack processing factories will give you a perceptual understanding of the entire process.

5. The last thing to examine is the brand: Brand not only means higher price, but also means quality assurance and after-sales commitment.
