Outdoor mountaineering bag carrying system

The structure of an outdoor mountaineering bag can be divided into three parts, namely the carrying system, the loading system and the external hanging system. Now I will introduce to you the carrying system of the mountaineering bag.

The carrying system of the mountaineering bag

The carrying system of the mountaineering bag to ensure comfort and load-bearing includes: double shoulder straps, waist belt, chest strap, force adjustment Straps, backpack support mechanism and adjustment device. The biggest difference between mountaineering bags is the carrying system. The design of the carrying system of a high-performance mountaineering bag not only considers ventilation, but also considers the ease of force transmission, comfort and load-bearing strength. In the early days, the most common support mechanism of mountaineering bags was U-shaped tubes or double supports. In order to enhance the stability of the backpack, modified backpacks adopted ""-shaped supports. Recently, the German BIG

PACK company produced The PERFORMICXILIE series backpacks are supported by an alloy tube frame. The materials are shaped using high-strength and high-elastic alloy tubes, which not only reduces the weight of the support material, but also makes the force more even. Its varieties above 55 liters also have a waist. Support makes the bearing capacity more integrated. In terms of shoulder fulcrum processing, the PERFORMIC series uses soft ventilated material ridges. A saddle is formed on the back to provide good ventilation.

The backpack adjustment mechanism of the mountaineering bag can be divided into upward adjustment type and downward adjustment type. The upward adjustment type generally has an adjustment point at the root of the shoulder strap, while the downward adjustment type installs an adjustment device in the middle of the waist belt. The back size can be adjusted according to the height of the wearer, but subject to certain restrictions. The PERFOMIC series adopts the stepless adjustment method of shoulder and waist connection, which completely overcomes the limitations of the first two adjustment methods. The wearer can adjust to the best position according to personal needs. The shoulder straps of professional mountaineering bags are all equipped with force-bearing straps, with one or two sets of adjustment fulcrums. Their function is to adjust the distance between the shoulders of the backpack and bear the gravity of the upper part of the backpack to act evenly on the waist. The chest strap can adjust the distance between the shoulder straps to enhance the stability of the backpack and facilitate breathing.

How to choose a mountaineering bag

1. Fabric

The fabric of the bag must be strong, wear-resistant, and have certain waterproof properties. Bag fabrics are usually made of high-strength nylon, and XXX D (Denier) is generally used as the strength standard. The higher the value, the better. Generally, the 420D fabric of low-priced bags is relatively strong and can be used for most hiking needs. Most of the famous brand bags use fabrics above 500D or even better DuPont fabrics. These fabrics can be used in more harsh environments. Cheap bags usually do not have instructions on the performance of the fabric. It requires your experience and knowledge. If you are not sure, it is better to be careful. PU coating can make your bag more waterproof. Low-end backpacks are mostly made of PVC coating, which will harden when exposed to cold, while high-end backpacks are mostly made of PU-coated fabrics, which have no significant change in hardness when exposed to cold. Four PU coatings The waterproofness of the fabric can reach more than 1500MM. At present, the famous brand backpacks on the market are more sophisticated in materials and have better performance and quality. Check to see if the surface inside your bag is even. However, in order to meet the functional needs, the mountaineering bag has many seams and does not have a rain cover, which will be very troublesome when it rains heavily.

2. Quality of fasteners

It may be the most easily damaged part of the bag. It is easier to judge the quality of fasteners. First, observe the workmanship of the fasteners. If The fasteners are very rough, the edges of the fasteners are also uneven, and the hand feel is very bad. Then don’t look at this bag anymore. It must be garbage?! The workmanship of the fasteners can most intuitively reflect the overall bag. quality. Secondly, if the workmanship of the fastener is good, in order to better test its performance, you can bend the legs of the buckle. High-quality fasteners can bend more without breaking. Some bosses will take the initiative to bend it 90 degrees for you to prove its quality. Be careful with unmarked fasteners of unknown origin.

3. Stitching

Your bag cannot be made of a whole piece of fabric. There must be nylon threads for sewing. These tasks are all done by machines. The stitching of a well-made bag should be neat, dense and even. There should be double stitching at stress points to ensure it is strong. In this link of sewing, you can see the attitude of the manufacturer producing this bag and the performance of the machine.

You should give up on workmanship with threads everywhere and crooked threads! No matter how strong the fabric is without qualified stitching, it will give you a fatal blow at a critical moment!
