The improper design of the carrying system of the early backpacks often caused the climbers to have sore shoulders or cramps or numbness and pain in the fingers during the climbing process. On the contrary, the design of today’s backpacks is not only comfortable, even if the weight of 30 kilograms is like 20 The feeling of kilograms, and the material of the backpack has also developed from canvas to nylon cloth and aluminum alloy skeleton.
According to different mountaineering routes, climbers should have two different types of mountaineering backpacks:
(1) Large backpack: for multi-day camping activities, the skeleton of this backpack ( (i.e. shoulder to hip) design is divided into built-in type and outer frame type.
(2) Soft backpack: one-day round-trip suburban mountain and rock climbing activities.
Framed backpacks
Early backpacks are all of this type. The frame of the skeleton is H-shaped, and the carrying system only relies on thick shoulder straps, which causes the backpacker to carry a backpack while hiking. The skeleton is easy to shake, and it is difficult for the body to maintain balance when encountering strenuous activity routes, such as the intermediate mountain activity route of walking in the arrow bamboo forest, the river tracing activity of climbing bare rock, and the long-distance vertical walking activity of jumping on the bare rock pile. A variety of different means of transport are easy to cause many troubles in the transportation process. For example, it is not suitable to take a crowded bus, it is easy to be refused to take a taxi, or it is difficult to travel by plane overseas.
Currently, the carrying system of the outer frame backpack is divided into 1. shoulder strap, 2. chest strap, 3. waist belt
, which combines the bearer and the backpack and distributes the weight, although most outer frame backpacks have many small sides The bag provides storage, but the center of gravity of a solid outer frame is usually higher than the shoulders and waist, so its center point of load causes the wearer to lean forward for balance, while the rigid frame of the outer frame will Reducing the rotation space between traveling and the high center of gravity make it difficult to maintain balance during traveling.
The carrying method of the external frame backpack is to adjust the waist belt first, and then adjust the shoulder strap. The fixing point on the top of the shoulder strap must be at the same height as the shoulder, the spacing of the shoulder strap should not make the neck uncomfortable, and the buckle of the shoulder strap must be Fasten the frame tightly and do not slide freely. The belt must be aligned with the hip bone (ischial bone), the spacer of the belt must be tightly around the seat bone, the end of the belt does not need to intersect at the front, the belt must be able to be adjusted up and down, and try not to make the horizontal under the frame. The rod touches the back.
If the shoulder strap is set too high, the center of gravity will move to the front of the body, or if the shoulder strap is set too low, the center of gravity is completely loaded by the shoulder strap, and the waist belt will not share any force, which will cause the backpack to shake during walking. , the shoulder strap will have a device to adjust the center of gravity connected to the frame, it must be lower than the shoulder height of the bearer, the adjustment method is an ear shape, just in front of the collarbone, this device must be tied tightly to transfer the weight to the shoulders, otherwise It is easy to shift the weight to the waist.
Built-in skeleton backpack
When you go to the mountaineering equipment store to buy a built-in skeleton backpack, you will usually be dazzled by the colorful backpacks of different sizes. Confused, I don’t know where to choose.
The skeleton of this backpack is made of aluminum alloy or carbon fiber. The skeleton of the backpack is divided into adjustable and non-adjustable types. The skeleton is covered with a plastic cover. The purpose is to protect the backpack fabric and support the spine, and make the backpack stand upright. It is a streamlined design. Although the price of this type of backpack is relatively high, this type of backpack can fit closely to the body of the bearer, even if walking on an intermediate mountain, etc. It is not easy to be hooked by branches, but this type of backpack will make your body bend at an angle greater than that of the outer frame backpack.
A good shoulder strap design can make the weight distributed on the shoulders, the thick spacer of the waist belt must be elastic and just support the waist, and at the same time, the weight of the backpack can be effectively transferred to the pelvis, and the back side of the backpack is best Polyethylene padding allows the pack to fit snugly against the back, while items such as camp posts or pot sets inside the pack will not protrude and be uncomfortable for those on the back.
Soft backpack
It is a multi-purpose backpack, light-loaded single-attack, single-day suburban or rock climbing activities, the opening is designed for both top and horizontal, the top-open backpack, items It is more difficult to load and take. The durability of a backpack with a horizontal opening depends on the durability of the backpack zipper. Therefore, it is best to choose a zipper with a thicker tooth. The horizontal opening is larger, and it is easy to load and take items. There are backpacks that combine both designs.
For climbing in suburban mountains, it is better to use a backpack of 45 to 55 liters if you are traveling with your children. The backpack is best without side pockets. Although some people like to put small items such as maps, gloves, and food in the side pockets, it is difficult to climb a backpack with side pockets when traveling. In non-snow seasons, use a backpack with a semi-circular zipper to fill it. It can be neatly placed and stable for climbing, and the backpack will not shake.
