â–² general or low-intensity recreational activities, travel items will not need to carry too much, so do not ask for the backpack. However, some people do not have enough outdoor experience. The backpack is stuffed with a lot of things that are not very useful, including very heavy clothing, large insulation pots and even a variety of gourmet drinks. In this case, an ordinary backpack is difficult to adapt to such a weight. Even if the bag can cram a lot of things, the carrying system of an ordinary backpack cannot disperse the weight of the backpack to the back in a reasonable manner. Hardship or even the risk of injury in the end. And try to liberate your hands when traveling, and even some scattered things are packed into the backpack.
â–²A day's leisure and outdoor activities, such as the crossing of the Baihe River and the bottom of the river. Since the walking distance and time will be more, the load should be controlled within 8KG . Selecting a 15-30L outdoor backpack will make your journey very easy.
â–² A day of high-intensity outdoor activities such as wearing three peaks and arrows. The requirements for backpacks are much stricter. Because it is high-intensity activities, it is necessary to keep lightness as much as possible. Food and clothing are mainly practical, and weight control is appropriate around 6-7KG . The first choice for backpacks is to bear comfort . When you are walking, try to tighten the belt so that you can effectively reduce the pain on your shoulders.
â–² Two or three days of activity, even if it is a leisure activity, requires a slightly larger capacity backpack, because the food and equipment needed to be carried out for a few days will be more, 35-45L is more appropriate, if the weight is too large, Also need a good carrying system , ordinary backpack will not go too hard for a short time, take a long time back pain.
â–² Reloading activities or long-term outdoor activities, the choice of backpack is more cautious, because the reloading activities need to put the tent sleeping bag moisture cushion on the backpack, and some things even need to hang outside the backpack, usually carrying The weight will reach 20KG or more, and an ordinary backpack can not adapt to such weight at all. The piggyback system is particularly important. When selecting a reloading package, choose a reloading package that suits your needs. When traveling, place the weight of the entire backpack on the waist as much as possible . If the weight of the shoulders is sustained for a long time, you will suffer. The wide and thick belt shoulder straps can also fully protect the waist and shoulders. Will give you unlimited sense of relaxation.
The choice of outdoor backpack can be roughly referenced according to the following:
If you travel a short time and are not ready to camp outside, carrying a small number of items, should choose a small volume of backpacks, generally 25 to 45 liters is enough . The general structure of this kind of backpack is relatively simple, there is no external plug or a few external plugs. In addition to a main bag, there are usually 3-5 attachments for easy loading of items. If you travel longer , or need to bring camping equipment, you must choose a large package, with 50 liters -70 liters is appropriate . If you need to load more or more bulky items, you can choose 80+20 liters of large backpacks, or more backpacks.
The same as a mountaineering bag, its use is not the same . For rock climbing bags designed specifically for rock climbing activities, hard supports are generally not designed so that they are easy to carry along with a large number of external points in order to facilitate the installation of hanging equipment. Some models are also equipped with cloths for finishing equipment. The bicycle series designed for cycling has paid more attention to the characteristics of cycling. It can be divided into back packs, rack bags, front packs, back packs, and bags . The basic hiking bag, also known as a camping backpack, is designed to take into account the characteristics of various forms of operation and the need for long-distance marching. It is suitable for climbing, adventure and woodland crossings. There are backpacks specially designed for long-distance travel. They are called multi-purpose bags or sub-packages. Their split structure is basically the same as that of climbing bags. They can be double-shouldered, layered up and down, and are similar to suitcases. , can be a single shoulder, can also be horizontal and vertical to mention the line, the size of the packaging with a conjoined structure, can be divided into convenient use, very popular with business travelers.
What kind of size is appropriate? Generally speaking, the waist point of the backpack should be on the flank above the coccyx. The fulcrum of the shoulder strap should be generally lower than the shoulder and slightly lower than the shoulder, so that it is convenient for the adjustment and force of the force belt to be comfortable . The back size is too large to produce a sense of falling, and vice versa, there will be a sense of falling, so that the waist is not in place. After the proper size is adjusted, the backpack will naturally be comfortable on the back.
The material of the backpack also developed from canvas to Nylon cloth and aluminum alloy frame.
The quality of a rucksack is not only to see its capacity, waterproof performance, but also more important is to see if its carrying system is designed according to the physiological curve of the general back, adjustable. The early backpack's carrying system was improperly designed, often causing the climber to climb during the process, shoulder pain or cramps or finger numbness, the opposite of today's backpack design, not only comfortable, even if carrying a 30 kg weight is like a feeling of 20 kg ,
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. When long distances that require multiple days involve walking, whether the backpack has a flexible capacity design.
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.
Whether there is a removable side pocket, 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 technical climbing or in the jungle, 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 zip failure backpack can still be used?
Backpack recommendation
In fact, small packets do not have too much stress, look good enough to use the benefits on the line; heavy bag must be carefully selected, because it is not easy to bear the dead ! The King of weights is Gregory, the preferred granite for light weight, and Kayle Stone for cheaper choices.
