How to choose a big backpack for mountaineering activities?

It can be said that as long as it is an all-night mountaineering activity, you need a big backpack. The predecessors once said: Your home is on your back, but everything you eat, drink and sleep in is in this backpack. According to the shape, large backpacks can be divided into two categories: internal (commonly known as straight backpacks) and external (commonly known as aluminum backpacks). The straight backpack is mainly supported by the shelf near the back of the user inside the backpack, and its internal support will bend with the user's bones. As long as it is properly packaged, the center of gravity of the whole backpack will move with the user, which is very ergonomic. The aluminum frame backpack has a large surface accumulation and poor waist and shoulder design, which often makes people feel sore and backache when carrying loads, not to mention drilling bamboo forests or crossing other difficult terrain!

However, the aluminum frame backpack has a good compartment, and there are many large and small pockets, so it is very convenient to pack things. There are two prices for domestic straight backpacks: imported and domestic. The recommended purchase quantity is 60-80 liters, the import price is about10.5 million, and the intermediate product is 200-500 yuan. Imported backpacks are guaranteed to work, and there are different degrees of changes or innovations every year. Domestic backpacks do not provide use guarantee, and most of them copy the appearance of foreign famous backpacks. The disadvantage is that the quality is unstable and the situation is frequent. Aluminum backpack is not suitable for mountain climbing or long-distance hiking, but it is also a good choice if it is only used for camping in the wild or hiking in open terrain. Most of the aluminum backpacks available in the market are made in China, and the price is between 200 and 500 yuan. In addition, there are a small number of imported American-made backpacks with outer frames, advertised as "the comfort of straight backpacks and the convenience of aluminum backpacks", and the price jumped from 2000 yuan. If you are interested, don't try.

Mountaineering bag

Two kinds: one is a large backpack with a volume of 50-80 liters; The other is a small backpack with a volume of 20-35 liters, also called "assault bag". Large mountaineering bags are mainly used for transporting mountaineering materials in mountaineering, while small mountaineering bags are generally used for climbing at high altitude or assaulting peaks. The mountaineering backpack is made to cope with extreme environment, which is exquisite and unique. Generally, the bag is slender, and the back of the bag is designed according to the natural curve of the human body, so that the bag is close to the back of the person and the pressure of the strap on the shoulder is reduced. These bags are waterproof, so they won't leak even in heavy rain. In addition, mountaineering bags are not only used for mountaineering, but also widely used in other adventure sports (such as drifting and crossing the desert) and long-distance travel.

travelling bag

Large travel bags are similar to mountaineering bags, but the shape of the bag body is different. The front of the travel bag can be completely zipped open, which is very beneficial to take and put things, unlike mountaineering bags, which usually put things into the bag from the top cover. There are many kinds of small travel bags, so you must choose the one that is comfortable to carry, not just the appearance.

Bicycle special bag

There are two types: hanging bag type and backpack type. The bag-hanging type can be carried on the back, or hung on the front handlebar or rear frame of the bicycle. Backpacks are mainly used for bicycles that need to ride at high speed. Bicycle bags are equipped with reflective strips, which can reflect light and ensure the safety when riding at night.

Back frame bag

This bag consists of a bag body and an external aluminum alloy shelf. Used to carry large items that are not easy to pack into backpacks, such as photo boxes and gas tanks.

In addition, many backpacks often indicate which sports they are suitable for on the sign.
