How to choose a good outdoor backpack

The most indispensable thing for hiking, camping, and outing is backpacking. In addition to being refreshing and refreshing, a good backpack can carry a lot of things, free your hands, and keep your body in balance, making your trip safer and more comfortable. However, it is not so easy to find suitable suits for backpacks of various sizes. Establishing a concept about backpacks in your mind allows you to walk safely and comfortably.

A backpack fabric - not just "face

At present, the materials commonly used in backpacks are "nylon" and "Cordura". Although canvas is more wear-resistant, it is rarely used because it is easily damped, wet and difficult to dry, and heavy. Nylon cloth is lighter in weight, does not absorb moisture, mold, fast drying, and has good strength; the disadvantage is not wear and fire. Cordura cloth is also a synthetic nylon cloth, but it performs better in terms of wear resistance and strength than nylon. It also does not absorb moisture, mold, and stick to snow and is quick-drying, but slightly heavier than nylon.

Second, capacity - not only can bring much things

Capacity is an important factor in choosing a backpack. The capacity is not enough. Hanging an item outside is both cumbersome and easy to lose. If the capacity is too large, the backpack is not easy to pack when it is packed. The equipment in the package will affect the balance due to movement. So, choose backpack capacity first to establish personal equipment list.

Some of the equipment used in mountaineering, such as raincoats, warm clothing, and sleeping bags, are articles that do not diminish over time. They are relatively stable in size and weight. However, food and fuel are consumables, which decrease with the increase of activity time. The quantity of such items has a great influence on the capacity of backpacks.

Nowadays, some backpacks are designed with "elastic capacity". Even if the backpack can still be made solid after several days of activity, the backpack can be applied to different areas of activity. In general, small and medium sized backpacks do not need this design, and no one else designs them. If you want to change the size of the bag, you can adjust it by adding side pockets or adjusting the compression side.

Third, carrying the system - the skeleton of the backpack

The backpack carrying system can not completely solve the problem of the weight of the backpack. Its main function is to distribute the weight to all parts of the body and prevent the weight from being concentrated on the shoulders. In addition, it also provides adjustment of the burden of gravity in order to increase the balance and safety during the operation. The medium and large-sized backpacks usually form a piggy back system with the back frame as the center, and the back frame can be divided into two types, the outer frame type and the inner type frame type.

Outer rack backpack

Outrigger backpacks are designed to hold the carrier bag on a rigid frame (the most common type of aluminum alloy), with a taut nylon shoulder strap and hip strap. The center of gravity of this backpack is high, about the shoulder or shoulder. Although the high center of gravity design is not suitable for applications that require a high degree of balance, it is more comfortable to carry the burden on a flat road. This kind of backpack is also easy to load and use, and can make the weight shared by the shoulders and buttocks. Since the outer rack type backpack is carried by the rack, the ventilation of the back is good.

Frames can become inconvenient in certain situations: For example, when you are driving in jungles or bamboo groves, the backpack is easily hooked and jammed; when you are climbing or skiing, it is easy to shift suddenly and lose weight. In short, outrigger backpacks are more suitable for long journeys on flat roads.

Inner rack backpack

The center rack backpack has a slightly lower center of gravity and can be adjusted between the shoulders and buttocks. Suitable for climbing occasions that need to be balanced, preventing the backpack from shaking at shoulder height.

Fourth, backpack purchase - vary from person to person, according to local conditions

The adjustment range of the shoulder strap must be consistent with the length of the back so that the center of gravity can fall in the ideal position; the hip belt must be able to tie on the sacrum. You should also be able to see the hips and legs from behind when lifting your backpack. Women with smaller bodies should pay special attention to this point. Do not look back on the backpack and calf when carrying the backpack. This is very wrong and dangerous.

Before purchasing a backpack, you should loosen all adjustment belts and add weight, because if you don't have weight, you can't know the feeling of your backpack, whether it is appropriate to carry the adjustment range, and you should check the arc and back curve of the built-in aluminum bars after carrying the backpack. If not, check whether the aluminum strip is bendable; if it is bendable, the aluminum strip will naturally bend into a curve that matches the back when used for a period of time. Shoulder straps and backpacks must be 5-8 cm below the shoulders, and the space between shoulder straps and backpacks should be small. The chest strap adjusts the width of the shoulder strap at the front of the chest and makes the shoulder strap more comfortable on the shoulder and prevents the backpack from shaking. Good at using these adjustment straps and filling techniques, you can adjust the weight between your shoulders and hips so that different muscle parts can share the weight.

When adjusting the backpack to the most suitable position, check the sight of the head? Can you look up and not touch the top of your backpack? Can you still look up to the sky while wearing a helmet? Is the backpack and back contact part comfortable and breathable? Special attention should also be paid to the width and quality of the shoulder straps and hip pads.

In addition, there are some details that need attention:

Whether there is a double bottom fabric design, this feature can greatly extend the life of the backpack.

Whether there is a tow ring, hanging ice axe ring. The multi-day long distance journey involves whether the backpack has a flexible capacity design when walking. Whether there is a design of the compression side belt, it can tighten the backpack to reduce the backpack capacity when the equipment is reduced to prevent the movement of the equipment within the backpack when the movement shifts to affect the balance of the travel.

Is there a design that can easily carry crampons, sleds, snow shoes, trekking poles?

Whether there is a removable side bag, this feature can make the backpack more flexible.

Whether the backpack has a chest strap design, it can prevent the backpack from moving in difficult and bad terrain.

If the backpack is used for climbing or jungle, you should choose a backpack with a smooth shape so as not to be entangled by branches or rocks.

Backpack fabric materials should be sturdy and wear-resistant, and more in line with the needs of field activities.

Will the zipper of the backpack be directly stressed? If it is directly stressed, how is it limited by its force? If the zipper fails the backpack can still be used.

V. Backpack loading - great stress

Poorly loaded backpacks can affect ease of use and comfort, or cause center of gravity shifts and backpack damage. Therefore, when loading a backpack, apart from classifying various items according to their use, there are two points to note: the first is that the center of gravity is balanced; the second is accessibility.

The following is the filling principle:

1, the heavier items placed in the upper and as close to the back, can make the center of gravity tight back to avoid feeling pulled back. Large, light-weight items can be placed on the bottom so that it does not affect the center of gravity. In addition, because the weight is on the top, the backpack can be dense when used for a period of time.

2, hard objects do not put on the back of the site, otherwise if it is for the inner rack backpack will be directly to the back and very uncomfortable, even when the fall will hurt the back; if the outer rack backpack because of the hard goods and The back frame is only a layer of backpack cloth, it is easy to wear the backpack cloth.

3, the weight of the items placed around the backpack should be similar, so as not to bias the center of gravity. Raincoats, drinking water, and what you use on the day should be placed on the top or most accessible place.

4. There is an idea of using item sorting bags: put similar items or items that are used simultaneously in the same bag for easy access, and even more so for small pieces.

5, to develop the habit of fixed-point placement: not only organize the backpack faster, and even if it is dark can also find the desired things in the backpack.

6, try to change the filling method, to minimize unnecessary hanging outside the backpack, because it will not only affect the safety of the action and not beautiful.

Sixth, backpack shoulder, shoulder - Recruitment stress

The upper shoulder and lower shoulder of the backpack are the basic actions for using a large backpack. The more commonly used upper shoulders are: two-legged standing and arching, two-handed shoulder straps refer to the front legs of the thigh, one hand first penetrates into the shoulder strap and shoulders to hold the backpack on one shoulder, and then the other hand also Quickly penetrate the shoulder straps on the other side to complete the upper shoulders of the backpack.

Another commonly used upper shoulder method is to drag the backpack to a higher place, and one can only put his hands into the shoulder straps with a single squat, and complete the upper shoulder movement after standing up. Do not rush forward after completing the upper shoulder movement. Adjust the various adjustments of the backpack and adjust it in the most comfortable manner. Under the backpack is a reverse action, put down the backpack should be gently put down, heavy drop is easy to damage the backpack.

The second type of upper shoulders is not only less labor-saving, but also can be used as a short-term rest without putting down a backpack. When we rest halfway, we often lean the big backpack against the high side of the road. To facilitate the backpack or not to let go.
