I. Types of backpacks
-Small backpack (10L-30L)
1, riding a backpack. This type of backpack is suitable for riding and cross-country running, and its characteristics are helmet fixing point water bag bin.
2, business backpack. This type of backpack has a partition layer to hold notebook computers, the partition layer can be used to store business supplies such as documents, business cards and so on.
3, urban leisure backpack. This is for ordinary city tours. Cycling backpacks and business backpacks can be used as urban leisure bags, but urban leisure bags can’t be used as cycling bags and business bags because they don’t have their functions.
4, ice climbing, rock climbing backpack. This type of backpack is 20L-30L. It is characterized by the fixing points of ice claws and ice picks and the equipment ring.
-Medium backpack (male 55L-70L, female 40L-65L)
1, hiking backpack. This type of backpack is recommended to buy big rather than small, and can be used for both long-term and short-term activities.
2, snow mountain climbing backpack. According to different climbing methods, this type of backpack is suitable for Himalayan mountaineering. The so-called Himalayan mountaineering is to fight in a team style with the help of all external forces. You don’t have to carry too many things yourself, just climb it yourself. Originated in China.
-Large backpacks (more than 80L for men and more than 70L for women)
1, long-distance hiking backpack. Because long-distance hiking takes a long time, you have to carry everything you need to live, use, eat and drink, so you need a big backpack.
2, alpine snow mountain climbing backpack. The so-called alpine style refers to the way of climbing the snow-capped mountains by relying on personal strength and professional skills without any external force (exploring the climbing route by yourself, setting the protection points by yourself, and carrying everything such as technical equipment by yourself). Originated in Europe.
2. Composition of backpack
1. Fabric
The outstanding fabric is cordura fabric, which is produced by DuPont in the United States. Its characteristics are light weight and high wear resistance. The unit index of abrasion resistance is expressed by Daniel number (a term in textile science) and by the letter D, which means the gram weight of 9000m silk (this is an international fixed standard). The bigger the gram, the thicker the silk and the higher the wear resistance. For example, 420D, 600D and 1000D respectively indicate that the gram weight of 9000m silk is 420g, 600g and 1000m. The bigger the gram, the thicker the silk and the higher the wear resistance. The more expensive the corresponding backpack is. Cordura fabric is 200-300 d higher than ordinary fabric. This is why the price gap of backpacks with different fabrics is relatively large.
2. Ribbon
The outstanding ribbon is the ribbon of Hong Kong Victory, which is characterized by high strength, not easy to break and smooth.
3, buckle
The card points are divided into toughened buckles and plasticized buckles. The toughened buckles are strong and can hear brittle sounds. Plasticized buckle is weak. The best buckle is the French Duflex buckle, which translates into more wear resistance. -40 degrees can be used normally and is not easy to separate.
4, zipper,
Everyone knows this. The YKK zipper in Japan is characterized by no cracking, smoothness, normal use after repeated use for tens of thousands of times, and normal use at -40 degrees.
3. Backpack system
1. Center of gravity adjustment belt
That is, two adjustment belts are connected to the left and right of the shoulder strap and the head of the backpack.
2. Balance adjustment belt
It is the adjusting belt that links the middle of the shoulder strap and the left and right sides of the bottom of the backpack.
3, shoulder strap
Is the left and right straps on the shoulder.
4, back pad
Is to carry a backpack and stick it on your back. It is divided into American and European back cushions. The size of American back cushions is fixed and cannot be adjusted. The European back cushion is in different sizes and can be adjusted.
5, belt
Everyone should know that almost all outdoor backpacks have belts.
Step 4: Backpack
First of all, you can’t let the backpack bear the stress alone, otherwise it will accelerate the wear of the shoulder strap, and maybe the shoulder strap will be disconnected at the most critical time. It is conceivable that once the shoulder strap is broken, the backpack is equivalent to waste, which will bring great trouble. The specific steps are as follows:
1. Under normal circumstances, the backpack is from right to left, and your right foot is bent, as long as you can hold the backpack, hold two shoulder straps with both hands and put the backpack on your knees. 2. Insert your right hand into the shoulder strap on the right side of the backpack, hold the lower right corner of the backpack, and bend down at the same time to let the backpack press on yourself. In short, don’t let the backpack be stressed alone, and there is a point to support the backpack. 3. Put your left hand into the left shoulder strap and straighten up. 4. Finally, fasten your belt and chest strap. Next, I will talk about how to tie the belt and shoulder strap to make the body carry the bag comfortably.
