Two types: one type is a large backpack with a volume between 50-80 liters; the other type is a small backpack with a volume between 20-35 liters, also called "assault bags." Large mountaineering bags are mainly used for transporting climbing materials during mountaineering, while small mountaineering bags are generally used for high-altitude climbing or assault on the summit. The backpack for mountaineering is designed to cope with extreme environments. It is exquisitely made and unique. The body is generally thin and long. The back of the bag is designed according to the natural curve of the human body. This kind of bag is waterproof, so it won't leak even in heavy rain. In addition, mountaineering bags are also widely used in other adventure sports (such as rafting, crossing the desert, etc.) and long-distance trips in addition to mountaineering.
2. Bicycle special bag
Divided into two types: bag style and backpack style. The bag can be carried on your back, or you can hang the bag on the front handle or rear shelf of the bicycle. The backpack type is mainly used for bicycle trips that require high-speed cycling. The bicycle bag is equipped with reflective strips that can reflect lights to ensure safety during night riding.
3. Travel bag
The big travel bag is similar to the mountaineering bag but the body shape is different. The front of the travel bag can be fully opened with a zipper, which is very convenient for taking and putting things, unlike the mountaineering bag, which usually puts items into the bag from the top cover of the bag. There are many kinds of small travel bags, so be sure to choose a comfortable one, not just the appearance.
4. Backpack
This type of bag is composed of a bag body and an external aluminum alloy frame. It is used to carry items that are bulky and difficult to pack in a backpack, such as a camera box, gas tank, etc. In addition, many backpacks often indicate which sports are suitable for them on the signs.
