D. can not ignore the quality of materials when choosing a backpack, many people often pay more attention to the color and shape of the backpack, in fact, the key to whether the backpack can be strong and durable lies in the manufacturing material. From the webbing point of view, the price of ordinary webbing and high-quality webbing can be 3 to 5 times different, and the webbing bearing capacity selected by BIGPACK can reach more than 200 kg. Therefore, the material difference is also very big, so the two kinds of fabrics from the strength and wear resistance are very different in the friction machine destructive test on the fabric, the same 500D fabric, ordinary nylon fabric is damaged at 1075 RPM, and Dupont nylon fabric is damaged at 3605 RPM, its wear resistance is 3 times that of ordinary nylon. The famous backpack in the market is more sophisticated in materials, and the performance quality is also better..
E. Good structure and design is the guarantee of superior performance of the backpack. Mountaineering bag has good performance, the important factor is that its design structure is scientific and reasonable. Good design not only gives you the overall beauty, more importantly, you can get the enjoyment of excellent performance in use, we can see this intuitively from the design structure of BIGPACK TOP backpack. The structure of the carrying system absorbs the principle of the Nepalese panniers and adopts a double "V" design. First, the lining aluminum frame is "V" shaped, a cross bar is positioned at the shoulder, and the aluminum frame is shaped according to the human curve, and the user can also fine-tune according to the personal shape; The second is that the backpack loading part is a "V" font, the upper is wide and the lower is narrow, the upper is thick and the lower is thin, and the loading is a basket type, such a structure is more convenient for force transmission. ETA-3 adjusting device is adopted for the TOP series of shoulders. The adjusting part is provided with 3 holes, and a structural liner is installed in the device to adjust the position of the holes, which can change the size of the shoulders. Changing the position of the structural liner can make the center of gravity of the backpack move up and down. TOP series backpack is also designed to increase the volume of the device, the vertical capacity of the top bag is set under a zipper, open zipper can increase the capacity of the backpack about 10 liters, horizontal adjustable backpack is equipped with two vertical zippers on the main bag, after release can make the backpack thicker to expand the volume, especially suitable for loading larger items. Users can adjust their height and width according to their needs, and with such a backpack, it provides a lot of convenience for your travel. As for the use of backpacks, after you understand the structural principle of the hiking bag, its use is in no words. Here, we recommend a paragraph of Pagar's wise strategy for carrying heavy objects to readers for backpackers' reference.
We recommend that when in favorable terrain, the center of gravity should be shifted to the upper part of the backpack; When in a more unfavorable terrain, the center of gravity should be moved to the middle of the backpack. The general order of loading items from top to bottom is: supplies, drinks, heavier equipment, lighter equipment, sleeping bags and clothing, which can be tasted by the carrier in use.
