It can be said that as long as it is a mountaineering activity that requires a lot of sleep, the former person once said that your home is on your back, but all the things you eat, drink, use, and sleep are placed in such a backpack. .

However, aluminum rack backpacks have good compartments and large pockets, and it is an advantage that they are packed and packaged to make them very convenient. Straight backpacks have two kinds of imported and domestic prices in China. It is suggested that the purchase capacity should be between 60-80 liters, the import price should be around 1,500 yuan, and the medium goods should be from 200-500 yuan. Imported backpacks have guaranteed use and each year has varying degrees of innovation or innovation. Domestic backpacks do not provide guarantees for use and most of them are plagiarized outside of foreign brand name backpacks. The disadvantages of unstable quality and frequent minor situations are their disadvantages. Aluminum rack backpacks are less suitable for mountaineering or long-distance walking.

backpacks
Two types: One is a large backpack with a volume of between 50--80 liters; the other is a small backpack with a volume of between 20--35 liters, also known as an "attack pack." The large mountaineering bag is mainly used for transporting mountaineering materials in mountaineering, and the small mountaineering bag is generally used for high-altitude climbing or assaulting the peak. The mountaineering backpack is designed to deal with extreme environments. It is elegantly made and unique. It is generally thin and long. The back of the bag is designed according to the natural curve of the human body, so that the bag body is close to the person's back to reduce the pressure on the shoulder strap to the shoulders. These bags are waterproofed and will not leak even in heavy rain. In addition, mountaineering packs are used in mountaineering and are widely used in other adventure sports (such as rafting, crossing the desert, etc.) and long-distance travel.
Travel bags
The large travel bag is similar to the mountaineering bag but the shape of the bag is different. The front of the travel bag can be fully opened by the zipper, which is very convenient for picking and placing. Unlike the mountaineering bag, the bag is usually put into the bag from the top cover of the bag. There are so many small travel bags that you must choose to wear comfortable, not just look.
