What Are The Types Of Backpacks And What Are They Used For?

According to the different back volume, backpacks can generally be divided into three categories: large, medium and small.

The large back contains more than 50 liters, which is suitable for medium and long-distance travel and more professional adventure activities. For example, when you are going to a region like Tibet for a long trip or mountaineering expedition, 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 wild, because it is the only one that 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 different uses.

Hiking bags are generally slender and long, so that through the narrow terrain, the body is divided into two layers, separated by a zipper compartment, which is very convenient when accessing and placing items. The side and top of the backpack can be tied to the tent and mat, which invisibly increases the volume of the backpack. There is also an ice axe cover on the outside of the backpack for binding ice axes and snow poles. The most noteworthy is the back structure of these backpacks, there is a lightweight aluminum alloy inner frame that supports the body, the shape of the back is designed according to the principle of ergonomics, the back is wide and thick, the shape adopts an "S" shape design that conforms to the physiological curve of the human body, and there is a chest strap to prevent the strap from sliding sideways, making the backpacker feel very comfortable. And all of these backpacks have a sturdy, thick and comfortable waistband, and the height of the strap is adjustable. Users can easily adjust the harness to suit their height according to their size. Usually, the bottom of the backpack is located above the hips, which can transfer more than half of the weight of the backpack to the waist, thereby greatly reducing the burden on the shoulders and reducing shoulder damage caused by long-term weight loading.

The structure of the long-distance travel backpack is similar to the hiking bag, but the bag is wider and equipped with many side pockets to sort and place the bits and pieces, and the front of the long-distance travel backpack can usually be fully opened, which is very convenient to access and place items.

The volume of medium-sized backpacks is generally between 30~50 liters, these backpacks are more widely used, 2~4 days of field trips, trips between cities and some long-distance non-camping self-help trips, medium-sized backpacks are most suitable. You can pack clothes and some daily necessities. Medium-sized backpacks are available in a wide variety of styles and types. Some backpacks have added side pockets to make it easier to divide items. The back structure of these backpacks is roughly the same as that of large backpacks.
