Backpack, as the name implies, is a backpack used by climbers to load supplies and equipment. Alpine mountaineering bag is loved by climbers because of its scientific design, reasonable structure, convenient loading, comfortable load-bearing, and good for long-distance trekking. Nowadays, the significance of mountaineering bags is far from being limited to mountaineering. Some people also like to use such backpacks when traveling, hiking or fieldwork. A high-quality mountaineering bag is by no means a burden, it can give you value-for-money enjoyment, allowing you to complete travel and sports in ease.
The improper design of the backpack carrying system in the early days often caused climbers to experience shoulder pain or cramps or numbness and sore fingers during the climbing process. On the contrary, today's backpack design is not only comfortable, even if it carries a weight of 30 kg, it is like 20 kg. At the same time, the material of the backpack has also developed from canvas to nylon cloth and aluminum alloy frame.
Because of its scientific design, reasonable structure, convenient loading, comfortable and easy back, it is good for traveling long distances, so it is loved by people. Nowadays, the significance of mountaineering bags is far from limited to mountaineering. Some people who travel, explore or work in the field also like to use this type of backpack. The structure of the mountaineering bag can be divided into three parts, namely the carrying system, the loading system and the external hanging system. Eternal fulcrum, carrying system The carrying system of the mountaineering bag includes: shoulder strap, waist belt, chest strap, force adjustment belt, carrying support mechanism and adjustment device. The biggest difference between the advantages and disadvantages of mountaineering bags lies in the carrying system. In the design of mountaineering bags with excellent carrying system performance, not only ventilation must be considered, but also the ease of force transmission must be considered, and the comfort and load-bearing strength of the carrying must also be considered.
The most common support mechanism for mountaineering bags in the early days was U-shaped tube or double aluminum support.
To enhance the stability of the backpack, the improved backpack uses a "T" shape support. The Performic series backpack produced by the German BIGPACK company uses an alloy tube frame support, and its material selection system is shaped with high-strength and high-elastic aluminum alloy tubes, which not only reduces the weight of the support material, but also makes the force more uniform. For the varieties of more than 55 liters, a waist support is added to make the load-bearing force more integrated. In the treatment of the shoulder fulcrum, the performic series uses a soft and light ventilation material to bulge, forming a recess on the back, which solves the ventilation well. The backpack adjustment mechanism can be divided into up-adjustment and down-adjustment. For up-adjustment, an adjustment point is usually set at the root of the shoulder strap, and for down-adjustment, an adjustment device is installed in the middle of the waist 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 a shoulder-to-waist connection stepless adjustment type, which completely overcomes the limitations of the first two adjustment methods. The backer can adjust to the best position according to personal requirements. The shoulder straps of professional mountaineering bags are equipped with stress belts, with one or two sets of adjustment fulcrums, which are used to adjust the distance between the backpack and the shoulders and bear the weight of the upper part of the backpack; the wide waist belt of the mountaineering bag can make the weight of the backpack even The ground acts on the waist; the chest strap can adjust the distance between the shoulder straps to enhance the stability of the backpack and facilitate breathing. Reasonable space, loading system The loading system of the mountaineering bag refers to the part of the backpack to load items. The design is generally composed of a main bag, a top bag and a side bag. The main bag design is mostly up and down layered, that is, one at the top and one at the bottom. The opening has a movable compartment in the middle, which can be connected or disconnected. The advantage is that the user can divide the items according to the needs, and it is convenient to take out when used. Some backpacks are designed with side bags, or ear bags, like two ears on both sides of the backpack. For the convenience of external hanging, some bags have a movable side bag design, which can be installed at any time when in use, and can be removed when not in use or when using external hanging. Bundled art, external system A professional mountaineering bag, external system is essential. The outer hanging of the backpack can be divided into top hanging, side hanging, back hanging, bottom hanging, etc., usually in the form of point fixing or strip fixing. The point-hanging type generally has two or four corresponding hanging points, which are fixed by two-point or four-point binding when in use; the strip-hanging type is usually equipped with two rows of external hanging straps on the front of the backpack, each with a number of fixed points, and its fixed items More random and less affected by morphology.
Although all mountaineering bags are designed with external hanging points, most of them are not equipped with external straps. Users can use soft nylon ropes to fix them, or go to mountaineering equipment franchise stores to purchase standard external straps. Brand concept of backpacks Mountaineering bags have not been on the market soon in my country. The first hiking bag in my country is Niikko in Hong Kong. Having a high-performance hiking bag has become the wish of many backpackers. In recent years, many businesses are optimistic about the mountaineering equipment market and gradually stepped into this field. Nowadays, the brands that can be seen on the market are: Germany's VAUDE, BIG PACK, Switzerland's ONARK, South Korea's GIANT, and domestically produced Kailas (Kailas). These backpacks with no different shapes have different quality due to their differences in design, fabrics, and craftsmanship.
