A good outdoor backpack in addition to the equipment, the liberation of the basic functions of both hands, but also play to maintain the balance of the body, so that the trip more safe and comfortable role. What is more, but also allows users to look more stylish, with a pleasant mood effect.
So how do we buy and use the outdoor travel backpack? According to experts, the current backpack is mainly nylon and CORDURA two materials, which is actually a synthetic nylon cloth, with all the advantages of nylon, and more wear-resistant, but slightly heavier. After selecting the material, determine the capacity. In general, the backpack capacity of more than 50 liters of outdoor backpack, will use the "flexible capacity" design, even if the long-term activities after the backpack is still able to play a solid, but also makes this backpack can be applied to different areas of activity. And 50 liters below the small and medium-sized backpack does not need this design.
The most important factor in determining the comfort of a backpack is its carrying system. The main function of the carrying system is to distribute the weight reasonably to the various parts of the body, to avoid weight concentrated in the shoulder. In addition it also provides a balance of gravity to increase the balance and safety of the action. , The large backpack is usually the back frame as the center constitute the bear system, the back frame can be divided into two kinds of external and internal frame.
Outer-style backpack is the backpack fixed in a hard frame (aluminum alloy most common), there are tightened nylon shoulder strap and hip band. It is characterized by high center of gravity, about the shoulder or shoulder above. The high center of gravity is designed to fit on a flat road and is not suitable for situations where a high degree of balance is required. The advantage is that it is easy to carry the articles, and the weight can be shared by the shoulder and the buttocks, and the back ventilated is good.
Inside the backpack is no obvious frame, usually with removable or hidden side of the bag, the appearance of more narrow, so this backpack is often called "vertical backpack." Vertical backpack built aluminum frame stereotypes, and there are hip can be part of the weight transfer to the buttocks. Features are slightly lower center of gravity, can be adjusted between the shoulders and hips. Suitable for the need to maintain a balance of climbing occasions, to prevent the backpack in the shoulder height shaking.
Choose a good backpack, how to fill is also a knowledge. Poor filling will affect the ease of use and comfort, or cause damage to the center of gravity and backpack. Therefore, when loading the backpack in addition to the first items according to the use of classification, but also pay attention to the following principles:
1, the heavier quality on the upper and as close as possible to the back, so that the focus close to the back to avoid the feeling of being pulled back. Large volume, light weight items can be placed at the bottom, so do not affect the center of gravity; the other due to heavy pressure on the top, so use a period of time after the backpack will be more dense.
2, hard objects do not put on the back of the site, otherwise it will directly to the back of the back uncomfortable or even fall will hurt to the back, or because of hard objects and back only a layer of backpack cloth, it is easy to backpack cloth mill broken.
3, backpack placed on the weight of the items should be similar, so as not to shift the center of gravity. Raincoats, drinking water and what should be used on the day should be placed on the top or the easiest place to get.
4, there is the use of goods classification bag concept. The same items or the use of items in the same bag to facilitate access, scattered little things even more so.
5, to develop a fixed place to put the habit, so not only finishing backpack faster, and in the dark environment can also work out what you want.
6, try to change the way to fill, to minimize the unnecessary backpack outside the hanging, which will not only affect the safety of action and unsightly.
