How to choose the purchase strategy of mountaineering bag

If you choose to climb the mountain during the holiday, then you definitely need a mountaineering bag, which plays an indispensable role in your journey. As for its function, the following small series will tell you how to buy a mountaineering bag.

type

At present, there are common soft backpacks, outer bags and inner bags on the market. Which type to buy mainly depends on what kind of sports you want to take part in.

A soft backpack

There is no internal and external support, no good backpack system, similar to students' backpacks. Light weight and small size. But the simple handling system can't bear such a heavy load, and it is very uncomfortable to carry. Only suitable for general urban tourism, one-day hiking, or one-day mountain climbing in the suburbs.

The metal skeleton is outside the backpack, which is rare now. This bag has an H-shaped metal frame outside (aluminum alloy is the most common), which can be used to hang photographic boxes, stoves and other equipment, so it is very heavy. But compared with the inner bag, there is more space between the body and the backpack, so that there is better air convection between the body and the backpack, and the backpack can keep cool and comfortable.

However, when the bag is fully loaded, the center of gravity of the outer frame bag is higher, which is more dangerous in the case of bad road conditions. For example, when drilling holes in dense forests and bamboo bushes, the backpack is easily caught, and the center of gravity suddenly shifts and loses balance when climbing. Therefore, this kind of bag is more suitable for carrying large luggage on flat roads.

Moving the metal skeleton into the backpack to make the skeleton and backpack more integrated is the mainstream mountaineering bag type at present. The backpack is more comfortable and the center of gravity is more stable. Compared with the outer bag, this will make your activities more flexible and easier to master the balance. Especially at present, most brands adopt an adjustable backpack system, which is adjusted to suit your body shape and will be very comfortable to carry.

Of course, because the backpack is closely combined with the body, it will be hot and the air will not circulate easily, which is also a problem that many brands are paying attention to and solving now. Inner packaging is now the mainstream of the market, and it is divided into many types according to different needs. Next, the author will introduce it in detail.

What is the capacity?

The capacity of the inner shelf bag is generally between 15L and 120L. For the average traveler, a 50L-75L bag can do most of the long-distance travel. Of course, if you need to camp in the wild for a long time, such as walking through no man's land for several days, you may need 120 liters, but this is only a few. For ordinary outdoor enthusiasts, the capacity is generally considered from the following aspects:

Depending on the type of travel.

Short trip: travel 1-3 days, don't camp outdoors, and bring less things. You can choose small backpack, generally 20-40 liters.

Medium and long distance: if you travel for more than 3 days or need to bring camping equipment, choose a big bag, and 50L-80L is a long-distance backpack. Women suggest 50L-60L backpacks, and men choose 60L-80L backpacks according to their physical strength.

According to gender

Because men and women have different body shapes and endurance, the choice of outdoor backpacks is not the same. Short-distance backpacks can be used by both men and women. However, if you want to choose a backpack of 50L-80L or even larger for a long-distance trip or camping for more than three days, the average woman can choose about 10L less than her male counterparts. Many brands of backpacks are divided into men's and women's backpacks. It is recommended that women buy corresponding women's backpacks. They are comfortable and generally look better.

According to the length

Nowadays, many mountaineering bags have adjustable backpack systems, but they also have a certain range of adjustment, so it is very important to choose the size of the backpack system when choosing mountaineering bags.

If the size is too large, it will cause a feeling of falling, otherwise it will cause an upward feeling and make the waist stress not in place. After adjusting the appropriate size, the backpack will naturally stick to the back and be very comfortable. Therefore, before buying a mountaineering bag, it is best to determine the length of your trunk, that is, the length between your seventh vertebra (where your neck and shoulders are parallel) and the bone parallel to your hips.

Generally speaking, if your torso is less than 45cm long, you should buy a small bag. If your torso is 45-52cm long, you should choose a medium bag. If your suitcase is longer than 52cm, you should choose a big bag. Good manufacturers have extra-large (above 56cm) or small (below 40cm) bags, which can also be customized. Of course, the specific model of the mountaineering bag depends on the number of items you carry.

The structure of mountaineering bag

The structure of mountaineering bag can be divided into three parts, namely backpack system, loading system and plug-in system.

Burden system

The keyword "piggyback system" mentioned several times above finally appeared as the protagonist in this part. When buying a bag, you should not only look at the capacity and quantity, but also the size of the backpack system you want to use.

The backpack system of mountaineering bag includes: shoulders, belts, chest belts, stress adjustment belts, backpack support machinery and adjustment devices. What backpack system will sellers emphasize when recommending mountaineering bags, so what's the difference between these guys who are all English code names?

There are too many kinds of common backpack systems, and almost every big brand has its own characteristic system. Here are some typical examples for you. Even if you hear a name you have never seen before, you can refer to the characteristics of the following systems for query and comparison.

TCS: This is the patent of BIGPACK, a mountaineering bag brand. It is specially designed for long-distance bearings. Its unique composite design of U-shaped aluminum tube and H-shaped double titanium belt (both aerospace metals) is lighter and harder than the general aluminum alloy skeleton, and the adjustment is very convenient and easy.

CR frame: the bearing capacity is slightly lower than that of TCS system, but it is greatly simplified and the structure is lightened, which makes it play an excellent role in the middle-priced mountaineering bag. Its weight/volume ratio is the highest, so it is very suitable for extreme outdoor sports, such as rock climbing and adventure mountaineering. H-shaped large back frame enhances toughness and adopts aluminum-steel alloy metal, which is convenient to adjust and use.

EVO: The system is made of light materials, with ventilation function and adjustable design, which is suitable for beginners. The back frame is lighter than TCS/CR. The back pad is placed in the friction position, which is very comfortable.

DTS: the patent of the famous brand GREGORY. The design of the traction belt can increase the support of the backpack system, which can not only disperse the weight on the whole elastic steel bar, but also not be compressed into the space between the backpack and the body, and guide the weight to the belt and buttocks. The breathable and hygroscopic mesh shoulder strap design keeps the backpack in comfortable contact with the body.

Bird's eye view: aluminum inverted U-shaped pillar, 3-point support backpack design, breathable backpack system, even if the center of gravity closely fits the body, it can ensure that the backpack has good breathability, so that the fit and breathability do not become a contradiction.

Of course, the above seemingly complicated technical instructions are only part of the backpack system. In addition, shoulder straps and chest straps can not be ignored.

Shoulder strap: A well-designed mountaineering bag. The shoulder strap is thick and has the function of exhaust, so the weight is generally less than 1/3 and there will be no discomfort. After adjustment, there will be no gap between the backpack and your shoulder blades. A good mountaineering bag can adjust its weight distribution on the shoulders at will, and you can adjust it at any time according to your physical strength and environment.

Chest strap: used to adjust the distance between two shoulder straps. When using it, adjust it so that the backpack is close to the body and does not feel pressure. Chest strap has obvious effect in reducing shoulder load.

Backpack pressure belt: the main function is to adjust the capacity of backpack, store external equipment and keep the center of gravity unchanged.

Center of gravity adjustment belt: the connecting belt between the upper part of the shoulder strap and the backpack, that is, the center of gravity adjustment belt, usually keeps an angle of 45 degrees.

Generally speaking, the key point of the backpack system is: Can the backpack fit the body better? Can it be more breathable while fitting? Is the bearing capacity strong? Can you make your backpack lighter? Grasp these four points, and the seller will not dare to fool you with a bunch of strange nouns.

The author suggests that when traveling with more items, choose a backpack with less weight.

As the name implies, the loading system refers to the part of the mountaineering bag that loads the goods. Generally speaking, the design consists of a main bag, a top bag and a side bag. The design of the main package mostly adopts two layers, that is, there is an opening at the upper and lower ends and a movable interlayer in the middle, which can be connected or disconnected. When purchasing, you can pay attention to whether the side bag and top bag are detachable, whether there is a computer compartment, whether there is a water bag, whether the main bag has a hook, whether there is a design of elastic capacity, and so on.

external system

Mountaineering bags are generally fixed with points or belts. The hanging point is designed with an insertion point. There is generally no plug-in strap, so you need to prepare it yourself. You can use nylon ropes or buy special buckles. Straps are generally installed on the front of the backpack, and there are two rows of external straps, each with several fixed points. In view of this, we also need to buy according to our own needs. For example, is there a design that is convenient to carry crampons, sledges, snowshoes and trekking poles (usually on the side of the backpack), and can raincoats or coats be easily tied (usually there is a drawstring at the top of the bag)?

Pay attention to the details of the mountaineering bag

What is a good product? Easy to use and durable. Ease of use refers to whether it can bring you the greatest comfort, which has been well explained in the structural introduction in the last part. And this part is to answer the question of "durability". Durability depends on quality, and quality often depends on the success or failure of details (here, materials and accessories).

wood tissue

There are four kinds of mountaineering bag materials commonly used in the market: polyester, nylon, Cordura and canvas.

Polyester (polyester fiber): It is a good fabric with good strength, heat resistance and elasticity. But the dyeing performance is poor. If you have a high demand for color, it may be difficult to choose this type.

Nylon (nylon, polyamide fiber): light weight, not easy to absorb moisture, fast drying and good strength. But afraid of fire, poor wear resistance.

Cordura: It is a synthetic nylon, which is as difficult to absorb moisture as nylon and dries quickly. Its wear resistance and strength are better than nylon, but its weight is heavier.

Canvas: Wear-resistant. But it has poor waterproof performance, easy to get wet, slow drying and heavy weight.

Now you need to know a parameter: Denier (D), which is a parameter reflecting the strength of the mountaineering bag fabric. Denier is proportional to the thickness of silk thread. The larger the denier value, the thicker the silk thread. Generally speaking, 500DCordura is a strong and waterproof material. The bottom of the mountaineering bag is one of the most easily worn places. It is best to use 1000D Cordura fabric.

Besides, ordinary mountaineering bags themselves cannot be waterproof, so they should be equipped with waterproof covers. If it is a bag with its own waterproof function, PVC waterproof coating will generally be used, and PU coating is a relatively high-grade one. The coating of PVC material will become very hard at low temperature, while the coating of PU will not change much. The more times you apply it, the better the waterproof performance. For example, if a bag is coated with PU four times, the waterproof performance can reach 1500mm or more.

To sum up, when considering materials, we consider wear resistance (mainly bottom), water resistance, fabric weight, softness, tear resistance (many backpack parameters refer to grid cloth, that is, tear resistance), air permeability (porous mesh) and so on.

Subsidiary part

Ribbon: Ribbon is often a fragile part of mountaineering bag, so the ribbon quality of mountaineering bag can directly reflect the overall quality of mountaineering bag. You can consult the seller about the carrying capacity of the ribbon when purchasing. The bearing capacity of some high-quality products can reach more than 200kg.

Zipper: YKK zipper (original brand of zipper with guaranteed quality) with double ends is best. Before buying, please ask the seller whether the backpack can be used again if the zipper is broken.

Route: Well-made mountaineering charter routes should be neat, dense and even. There should be double needles at the stressed place to ensure firm. Don't choose works full of line drawings and winding lines.

Fasteners: waist buckle, shoulder buckle, back buckle, etc. If you are going to a cold area, you must pay attention to whether you can withstand the low temperature. Good fasteners have good toughness and will not break once fastened.

Other latest functions: Now many mountaineering bags are developing new functions while improving the necessary quality. For example, this backpack (as shown below) has an LED reflector at the bottom. This thoughtful design is very practical when we travel at night.

The control button of the backpack LED light-emitting board is designed on the shoulder strap, which has two modes: stable and flashing, and can be adjusted as needed. The light source comes from rechargeable batteries and can last for 4 hours. The battery can also be taken out of the backpack. Standard USB interface is convenient for charging and backpack cleaning.

In short, it is still an old saying: buy on demand. But there are some places to remind everyone: try to choose a more humanized design, such as whether the main bag has a side zipper? Can you fasten your belt? Is the bottom thickened? Do you have a whistle on your chest? If the side is elastic, is it elastic enough?

Procurement experience

Shopping experience: Be sure to try it back.

Whether the mountaineering bag is suitable for you is related to your length. Even if you examine all the parameters and types thoroughly, when you arrive at your destination and start to prepare for climbing, you find yourself as if you are carrying a pair of shackles on your back, and it is too late to complain. Therefore, before rushing to pay the bill, you must memorize it! The specific backtesting steps are as follows

1. Before the backpack, loosen all the adjustment belts and add a certain weight. If you have the weight, you will know the feeling of carrying the backpack and whether the adjustment range is appropriate.

2. After carrying the backpack, check whether the radian of the hidden aluminum strip matches the curve of the back. If not, check whether the aluminum strip can be bent. If it can be bent, the aluminum strip will naturally bend into a curve matching the back after a period of use.

3. The joint between the shoulder strap and the backpack should be 5-8cm lower than the shoulder, and the gap between the shoulder strap and the backpack should be small.

4. The chest strap can adjust the opening and closing width of the shoulder strap on the chest, so that the shoulder strap is in a comfortable position on the shoulder to prevent the backpack from shaking.

5. When the backpack is adjusted to the most suitable position, how about checking the line of sight of the head? Can you look up without touching the top of your backpack? Can you still look up at the sky with a helmet on? Is the contact area between backpack and back comfortable and breathable?

6. After the backpack system is adjusted, jump up and down to see if the center of gravity of the backpack has moved. If you move backwards, then check whether the adjustment between the shoulder strap and the backpack is too loose. If so, tighten it and adjust it repeatedly until you reach your ideal comfort level.

Backpack for half an hour, if it's not uncomfortable, it's quite comfortable to carry, so this mountaineering bag is still very suitable for you. If you are still uncomfortable after repeated adjustments, this mountaineering bag is not suitable for you. If the most suitable bag is needed, the aluminum bar can be removed from most bags with aluminum bars inside. You can bend your back according to its shape. At the same time, I don't approve of lending mountaineering bags to others. A bag worn for many years will deform according to your shape, so it is more suitable for you, so it is not recommended that you lend it to others.

In addition to the methods mentioned in the article, there is also a possibility to judge whether the mountaineering bag is suitable for you, that is, the utilization rate of the contents of the backpack and the discomfort caused by the cleanliness of the items. There is a sleeping bag compartment under the outdoor backpack, so there is no way to change the use. Put the heavy ones in the middle, near the back and the light ones outside. It is best to have full clothes and flexible shapes, so that the center of gravity is stable, the top bag is easy to take, waterproof and compact. This package.

1, the back time is too long, and the same burden will be very tired;

2. The shoulder strap fabric is not suitable for the shoulder, and the carrying performance of the backpack is not good;

3. The backpack is not adjusted to the best position. The backpack should be adjusted according to the back length. The belt should be on the bones on both sides to share the shoulder pressure, and the back should be completely attached to the backpack;

4. Your physical strength is poor, your shoulder muscles are weak, and you can't bear the weight;

Therefore, it is not comprehensive to judge whether a backpack is suitable for you only from the quality or adaptability of the backpack, a.
