How to choose outdoor backpack correctly

The most common type of backpack on the market, more than 90% of the backpacks that most of us buy belong to this type. Men's favorite "Tinker Bell" universal backpacks, computers, mobile phones, keys, wallets, charging treasures, data lines, paper towels and so on. , can hold anything. And no matter where you go to work, school, travel and shopping, you can recite it. It's invincible.

Overnight (overnight)

Simply from the type point of view, this is already an entry-level outdoor backpack, which can generally carry materials for 2-3 days. The volume is generally 40-60 liters, but it is not small. It depends on what you bring. For example, if you only bring 1 set of clothes and other full-loaded snickers, it will not be a problem to use them as survival bags for at least half a month. Most importantly, there is no special design for the storage of equipment used for long-distance hiking, because it is redundant.

Long-distance backpack (multi-day)

Backpackers' favorite, the most common and commonly used outdoor backpack. Usually 60-75 liters, with a metal frame design, can hold a lot of things without collapsing on the shoulders. The belt is designed to be wide enough, thick enough and large enough. After being tied, it can share the stress on the hips and shoulders above the waist with the internal frame structure. The specific details of each brand are slightly different, but they are roughly the same, which is suitable for people who travel 1 week or more.

Adventure backpack (adventure)

The top outdoor backpack is a must for mountaineering exploration. It is the size of an outdoor backpack, usually 75- 125 liters, and all tents, pots and stoves can be loaded. The professional's suggestion is that the filling weight should not exceed 40% of the carrier weight. I'm afraid it's too much. There are many places in the design where professional mountaineering equipment is externally hung. In addition, the materials of fasteners and other components require extremely high cold resistance and toughness, and the expensive parts are all details.

Technical backpack (technology)

Types of backpacks that climbers or skiers like. There are many places in the design suitable for placing and hanging climbing ropes, hooks, powder bags and even ice cones. Appearance characteristics are narrow and long, and the pursuit of convenience.

Sports backpack (hydration)

This kind of bag is generally not very big, and its purpose is only to carry common things with you. The highlight is that there is a special compartment to place the water bag, and the shoulder strap has a special straw fixed suspension design. In addition, small size, the pursuit of light weight, perspiration, ventilation. Suitable for people who like skateboarding, skiing, running and cycling, so this kind of backpack is also commonly known as cycling backpack.

Selection of outdoor backpack

light

Most people will have many different bags to meet different outdoor travel needs. But if you want to buy a so-called universal or universal backpack, you should first consider portability. When shopping, you can try to ask yourself a few questions like this: What do I usually do when I buy it? Where do I need it? I usually go out once a few days. What do I often take when I go out? The last one is very important, because if you are a lady who loves beauty, you'd better buy a box. )

frame construction

This is a very important point! No matter what backpack you buy, whether you are tired or not is always more important than anything else. After all, backpacks are the same as shoes. Others look good and they feel good. A good backpack system can distribute the force from shoulder to waist, not just a belt design. More importantly, it is a frame structure or a piggyback system. The frame structure of outdoor backpack is mainly divided into three categories: external type, internal support type and internal frame type, and the internal support type is better than external type.

There is no real aluminum alloy bracket outside, and frame structure design is not allowed in a narrow sense. It fixes the backpack on a hard frame (such as aluminum alloy), and the outer side of the backpack forms a buffer block through fillers such as foam or sponge to achieve the effect of shock absorption and decompression. This kind of systematic bag is usually not easy to carry too much.

The internal bracket is a professional backpack design, and the backpacks of this design are equipped with X-shaped or parallel double-track metal brackets. This design evolved from the earliest external metal bracket structure, which improved its design defects and lack of experience. Its function is to ensure that the back will not collapse when the backpack is full enough. So it's not hard to understand why your shoulders feel relaxed when you wear a belt.

The carrying effect of the inner frame is very close to that of the inner bracket, especially the actual experience on short-distance backpacks is not very different. As the name implies, this is a metal frame extending inside the backpack. Similarly, the existence of metal frame plays a vital role in backpack support. Advantages Compared with the internal support, it is lighter, but physically we know that the bearing capacity and anti-extrusion ability of this design are not as good as that of the support structure. Therefore, this design is rare in heavy backpacks (long-distance and adventure backpacks).

measure

Many people have a misunderstanding about the size of backpacks, that is, volume. The size mentioned here is not the size of how many things a backpack can hold, but the size that matches people of different sizes, which can be understood as height and width in a narrow sense. Height is measured from the upper end of the spine, the back of the neck and the protruding parts that can be clearly felt by the hands, all the way down to the upper edge of the hip joint and the posterior cranial fossa. (Refer to the figure below for the length of the spine segment corresponding to the backpack size.)

Another dimension that needs to be measured is the width of the backpack. We don't need to quantify this accurately, because all the mass-produced models are on the market, and the aspect ratio can't fit everyone perfectly. Generally, after carrying a backpack, the width of a backpack without a kettle on both sides is close to the waist width after you put on a wide coat, even if it is appropriate. If it is obviously larger, it is recommended to choose a smaller backpack even if the corresponding height matches you.

convenience

The convenience of using backpacks is mainly the design of pockets (especially several main bags). There are three common designs for the top opening: zipper, drawstring, drawstring and cover. These three designs have their own advantages and disadvantages. It's inconvenient to take things without a cover, and it's not good in rainy and snowy days (of course, you can also say a bird's waterproof glue zipper design).

Some people may ask, "There is basically no cover design for daily backpacks, but most outdoor backpacks have it. Why choose? " If you extend your understanding, you will find that when choosing a backpack, it is better to have a waterproof design (such as laminated edges) on the outside of the zipper than not. In addition, the design of the top opening is only an example, and it is important to choose with doubts. Which design is more convenient in the environment I use?

construction design

Never ignore the role of details in anything, especially bad design details. It is a truth that how much water a barrel contains is determined by a short board. The designer is more professional than us, and he will try his best to make the details perfect. But the use environment is different, and good design is often the beginning of "bad".

If you walk in a leafy forest, it doesn't mean that you can be invincible with a professional adventure backpack. Extra straps or unreasonable side pocket design will make you get caught by branches and may even cause an accident. When it is time to be concise, it must not be complicated. It is not difficult to understand why short-distance backpacks have given up so many functions in design. Why is this backpack so carefully designed? Do I need an open top or an open side?

weight

There's nothing to say about this. The best way is to go to the physical store to feel it. If it is online shopping, find a backpack at home and simulate the weight after filling it. Take it, take it. Sometimes an empty backpack doesn't look very heavy, but when you walk for hours with a full backpack on your back, you may think: Why is it so heavy?
