According to the different capacities of backpacks, they can generally be divided into three categories: large, medium, and small

A large backpack with a capacity of over 50 liters is suitable for medium to long distance travel and more professional adventure activities. For example, when you are going to Xizang for a long journey or mountain climbing adventure, you should undoubtedly choose a large backpack with a capacity of more than 50 liters. Some short - to medium-term trips also require a large backpack when camping in the wilderness, as only it can hold the tents, sleeping bags, and sleeping mats you need for camping. Large backpacks can be divided into hiking bags and long-distance travel backpacks according to their different uses.
Mountaineering bags generally have a thin and long body to pass through narrow terrain. The bag is divided into two layers, with a zipper interlayer separating them in the middle, making it very convenient for picking up and placing items. The sides and top of the backpack can be tied with tents and mats, which invisibly increases the capacity of the backpack. There is also an ice axe cover outside the backpack, which can be used to bundle ice axes and snow sticks. The most noteworthy feature of these backpacks is their back structure, which includes a lightweight aluminum alloy frame that supports the backpack body. The shape of the back is designed according to ergonomic principles, with wide and thick straps that conform to the physiological curve of the human body in an "S" shape. Additionally, there is a chest strap that prevents the straps from slipping to both sides, making backpackers feel very comfortable. Moreover, all of these backpacks come with a sturdy, wide, and comfortable waistband, and the height of the straps can be adjusted. Users can easily adjust the straps to a height that suits their body shape. Generally speaking, the bottom of a backpack is located above the hips, which can transfer more than half of the weight of the backpack to the waist, greatly reducing the burden on the shoulders and minimizing shoulder damage caused by long-term weight-bearing.
The structure of a long-distance travel backpack is similar to that of a hiking bag, except that the backpack is wider and comes with many side pockets for sorting and placing miscellaneous items. The front of a long-distance travel backpack can usually be fully opened, making it very convenient to retrieve and store items.
The capacity of medium-sized backpacks is generally between 30 and 50 liters. These backpacks have a wider range of uses, such as 2-4 days of outdoor travel, city travel, and some long-distance non camping self guided travel. Medium sized backpacks are the most suitable. The clothes and some daily necessities carried with you can fit inside. The styles and types of medium-sized backpacks are more diverse. Some backpacks have added some side pockets, which are more conducive to packing items. The back structure of these backpacks is roughly the same as that of large backpacks.
The capacity of small backpacks is less than 30 liters, and these backpacks are generally used in cities. Of course, they are also very suitable for 1-2 day outings.
