How to choose a mountaineering bag (Photos) Read the full article >>

The mountaineering bag, as its name implies, is a rucksack used by the climber to load material and equipment.

Because of its scientific design, reasonable structure, convenient loading of objects, comfortable and relaxed backs, and good long-distance travel, it is loved by people. The meaning of the mountaineering package is far more than mountaineering. Some people who travel, adventure or field work also like to use such backpacks. The structure of the mountaineering bag can be divided into three parts: the piggyback system, the loading system, and the plug-in system. The eternal fulcrum, carrying the system mountaineering bag carrying system includes: double back shoulders, belts, chest straps, force adjustment belts, carrying support mechanisms and adjustment devices.

The biggest difference between the advantages and disadvantages of the mountaineering package is that it carries the system. The design of the mountaineering bag with excellent system performance must not only consider ventilation, but also must be considered for ease of stress transmission. At the same time, the comfort and load bearing strength should also be considered.

The most common support mechanism for mountaineering bags is U-tube or double aluminum support in the early stage. Later, in order to enhance the stability of the backpack, the improved backpack adopts “T”-shaped support. Recently, the Perform series of backpacks manufactured by the French company BIG PACK Co., Ltd. adopts alloy tube frame support. The material selection of the bag is made of high-strength, high-stretch aluminum alloy tube, which not only reduces the weight of the supporting material, but also makes the force more even. Its 55 liters or more variety, also added a lumbar support, making the bearing load more seamless. In the treatment of the shoulder fulcrum, the performic series is bulging with a soft lighter ventilating material to form an ampoule on the back, thereby well solving the ventilation.

The climbing bag carrying adjustment mechanism can be divided into upward adjustment type and downward adjustment type. Upward adjustment is generally set at the base of the shoulder strap, and downward adjustment is to install the adjustment device at the middle of the belt. Although these two types of adjustments can also adjust the back size according to the height of the backpacker, they are subject to certain restrictions. The Performic series adopts the stepless adjustment of the shoulder and waist connection, completely overcoming the limitations of the first two adjustment methods, and the back can be arbitrarily adjusted to the optimal position according to individual requirements. The shoulder straps of professional mountaineering bags are equipped with force belts. One or two sets of fulcrum are provided. The function is to adjust the distance between the backpack and the shoulders to withstand the gravity of the upper part of the backpack. The thick waistbands of the mountaineering bags can make the weight of the backpack uniform. The ground is applied to the waist; the chest strap can adjust the opening distance of the double shoulder straps to enhance the stability of the backpack and facilitate breathing. Reasonable space, loading system mountaineering bag loading system refers to the part of the backpack loaded items, the design of a share of the main bag, top bag and side package composition, the main bag design uses multiple layers up and down, that is, the upper and lower each set One opening, with a movable compartment in the middle, can be connected or disconnected. The advantage is that the user can dispense the items according to their needs, and they can be taken out easily in time. This year, the German company Paige introduced a new four-door backpack. In addition to the upper and lower openings, new devices are opened on both sides. This will make it easier to pick and place items. (Because this type of backpack has a zipper opening, the backpack's rain resistance has decreased, and it should be added. Special rain cover). Some backpacks are designed with side bags, also called ear bags, like the two ears are located on both sides of the backpack. In order to facilitate the plug-in, some packages use the active side package design, which can be installed at any time when in use, and can be removed when not in use or when using a plug-in. The bundled art, plug-in system, a professional mountaineering package, plug-in system is essential. The backpack can be divided into top hanging, side hanging, back hanging and bottom hanging, usually fixed by point or strip. There are two or four corresponding hanging points in the hanging type. When used, two or four matching hanging points are used. Two or four rows of hanging straps are usually installed on the front of the backpack. Each of the hanging points has a fixed point. More arbitrarily, less affected by the form.

Although mountaineering bags are designed with hanging points, they are generally not equipped with hanging straps. Users can use soft nylon ropes to fix them, or they can go to the mountaineering equipment franchise stores to purchase the system-made hanging belts. The brand concept of backpacks The mountaineering bag was listed in China shortly afterwards. The mountaineering package that was first introduced in China was Hong Kong's Niikko (Niikko). Having an excellent mountaineering package has become the wish of many backpackers. In recent years, many businesses are optimistic about mountaineering equipment market, and gradually involved in this area, the market now can be seen brands: Germany's VAUDE BIG PACK, Switzerland's ONARK, South Korea's GIANT, domestically produced Alice and blue particularity. There are no big differences in these backpacks. Due to the differences in their designs, fabrics, and manufacturing processes, their quality is not the same. How to choose a backpack suitable for your own use? Can be considered from the following five aspects:

A. Choose the volume of the backpack according to the number of items to be loaded. If the travel time is short and you are not ready to camp outdoors, there are not many items to carry. You should select a backpack with a small volume. Normal instructions for 25 to 45 liters are enough. The general structure of this type of backpack is relatively simple, no external or less external plug, in addition to a main bag, usually set up 3-5 additional bags, easy to sort items, if you travel longer, or need to carry camping equipment, then To choose a big bag, 50 to 70 liters is appropriate. If you need to load more or more bulky items, you can choose 80+20 liters of large backpacks, or more backpacks.

B. According to the use of the backpack to choose the type of backpack is also a mountaineering bag, its use is not the same. For rock climbing bags designed specifically for rock climbing activities, hard supports are generally not designed so as to be easy to carry around. There are more external points to facilitate the hanging of the equipment, and some models are also equipped with cloths for finishing equipment. For the bicycle series designed for cycling, more emphasis is placed on the characteristics of cycling, which can be divided into back packs and sacks. The general sense of the mountaineering package, also known as camping backpack, designed to take into account the characteristics of various forms of movement and the needs of long-distance marching, suitable for mountaineering, adventure and woodland crossing activities. There are backpacks specially designed for long-distance travel. They are called multi-purpose bags or sub-packages. The sub-structures are basically the same as climbing bags. They can be double-shouldered and are layered up and down. They are similar to suitcases. , can be a single shoulder, can also be horizontal and vertical to mention the line, the size of the packaging with a conjoined structure, can be divided into convenient use, very popular with business travelers. In short, all kinds of backpacks have their unique scope of application, and the best option for purchasing bags is special packages.

C. According to the body's selection of carrying system, the carrying system of the backpack has a specific scope of application. Although the adjustable backpack has a large range of application and is not limited, it is very important to choose the size of the backpack to carry the system. What kind of size is appropriate? Generally speaking, the waist point of the backpack should be on the flank above the coccyx. The fulcrum of the shoulder strap should be generally lower than the shoulder and slightly lower than the shoulder, so that it is convenient for the adjustment and force of the force belt to be comfortable. The back size is too large to produce a sense of falling. On the contrary, there will be a sense of verticality, so that the force of the waist is not in place. After the proper size is adjusted, the backpack will naturally be attached to the back and it is very comfortable.

D. Can not ignore the quality of materials Many people in the selection of backpacks, often pay more attention to the color and shape of the backpack, in fact, whether the backpack can be strong and durable key to manufacturing materials. From the point of view of the webbing, the price of ordinary webbing and premium webbing can be 3 to 5 times worse than that of the webbing used by BIG PACK. Therefore, the material difference is also very large, the same 42D fabrics, ordinary fabrics 280 grams per yard, and high-density fabric weight 410 grams per yard, so the two fabrics from the strength and wear resistance are very different The destructive test on the fabrics on the friction machine was the same as the 500D fabric. The normal nylon fabric was broken at 1075 rpm, and the DuPont nylon fabric was broken at 3605 rpm. The wear resistance was 3 times that of the ordinary nylon. From the coating point of view, low-grade backpacks mostly use PVC coating, which will become hard when cooled, while high-grade backpacks use PU-coated fabrics. The cold hardness does not change significantly. The degree of waterproofness of four PU-coated fabrics can reach more than 1500mm. . The brand name of the current market is relatively sophisticated on the use of materials, performance and quality are also better.

E. Good structure and design are the guarantee of superior backpack performance. The mountaineering bag has good performance. The important factor is that its design structure is scientific and reasonable. A good design not only gives you the overall beauty, but more importantly, it allows you to enjoy excellent performance in use. We can see this intuitively from the design structure of the BIG PACK TOP毓 backpack. The structure of its piggyback system absorbs the principle of Nepalese piggyback and adopts dual "V" design. First, the lining aluminum frame is “V” shaped, a crossbar is positioned on the shoulder, and the aluminum frame is shaped according to the human body curve. The user can also fine-tune the body according to the individual's body shape; "" font, the width of the upper narrow, thick and thin under the load after the type of 篓-type, this structure is more easily transmitted by force. The TOP series is equipped with an ETA-3 adjustment device. The adjustment section is provided with three holes. The device is equipped with a structural gasket to adjust the position of the hole, which can change the carrying size. Changing the position of the structural pad allows the center of gravity of the backpack to move up and down. TOP series backpacks are also designed to increase the volume of the device, the vertical expansion of the top package under a zipper, release the zipper can make the backpack capacity increase of about 10 liters, cross-type backpack in the main bag is equipped with two vertical zipper , Relax can make the backpack thicker to expand the volume, especially for larger items. Users can adjust their height and width according to their needs. With such a backpack, there are many conveniences for your trip. Use of backpacks As for the use of backpacks, after you have learned about the structure of the backpacks, the use of backpacks is beyond words. Here, we recommend to the readers a paragraph of wisdom of the company's smart strategy for carrying heavy objects for reference by backpackers.

- We recommend that, when in a favorable terrain, the center of gravity of the backpack should be moved to the upper part; while in the more unfavorable terrain, the center of gravity of the backpack should be moved to the middle. The order of loading items is generally from top to bottom: feeding, drinks, heavier equipment, lighter equipment, sleeping bags and clothes.
