Selecting backpack quality is the key

The quality of large backpacks should be examined in five ways:

1. Materials: Oxford cloth, nylon, polyester cloth from 300D to 600D are generally used, but the texture, abrasion resistance, color, and coating may differ. The best is DuPont CORDURA fabric, which is strong, wear-resistant and tear-proof. Its performance exceeds that of other fibers. Recently, an ultra-lightweight CORDRA has been developed to minimize the weight of the package. The material used for the bottom of the package is stronger than the fabric, and usually 1000D nylon fabric is used more.

2, design: bag-shaped, carrying the system, space allocation, packet configuration, plug design, back heat wicking, rain cover and so on. Good backpacks have outstanding advantages in terms of design.

3, attachments: zippers, fasteners, closing rope, nylon belt are very particular about. The most popular good zipper is the Japanese YKK zipper, which is divided into domestic and domestic production. The best zipper is produced in Northern Europe. The quality of the fasteners is very high. DURAFLEX is the best. UTX-DURAFLEX is produced in Hong Kong. There are plastic and nylon parts. The plastic parts have better feel, hardness and sound. Nylon pieces have better toughness and greater elasticity. Compression webbing is relatively big, good or bad in appearance can be seen at a glance, and now more used is the Hong Kong Sheng Kei ribbon, tight, solid, good appearance.

4. Process: The level of processing technology is determined by the skills of the workers and the machine equipment, the multi-functional double-needle machine, the knot-typing machine, the one-time forming press, and the laminator. Programming and quality supervision also play an important role. Visiting some backpacking factories will have a perceptive understanding of the entire process.

5. The final inspection was the brand: the brand not only means higher prices, but also means quality assurance and after-sales service.

In terms of carrying the system, each backpack manufacturer has its own uniqueness, and is also the essence of the backpack. Different brands bear different things, and even the same brand is not the same in different series. Need to be based on the specific model of each package.

When purchasing a backpack, it is best to personally bear the test and adjust the various adjustment points on the backpack to suit your body shape. Usually the large backpack will have five points adjustable under the armpit shoulder straps, shoulder back straps, belts, chest straps and back carrying system. If you feel uncomfortable in some areas after adjusting each part, you can confirm that this backpack is not suitable for yourself, and you can choose other styles.
