The following are some recommended outdoor backpacks for you:

 1: Mountaineering bag:

There are two types: one is a large backpack with a volume of 50-80 liters at home; the other is a small backpack with a volume of 20-35 liters, also known as "assault bags". The large mountaineering bag is mainly used to transport mountaineering materials in mountaineering, and the small backpack is generally used for high-altitude climbing or assaulting the summit quietly. Mountaineering backpacks are designed to cope with extreme environments. They are exquisitely made and unique. Generally, the body is slender and long, and the back of the bag is designed according to the natural curve of the human body, so that the body of the bag is close to the back of the person, so as to reduce the pressure on the shoulders by the straps. These bags are all waterproof and won't leak even in heavy rain. In addition, mountaineering bags are widely used in other adventure sports (such as rafting, crossing the desert, etc.) and long-distance travel in addition to mountaineering.

  2. Travel bag:

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 through the zipper, which is very convenient for taking things. Unlike the mountaineering bag, the items are usually put into the bag from the top cover of the bag. There are many kinds of small travel bags. Be sure to choose the one that is comfortable to carry, not just the appearance.

  3. Bicycle special bag:

It is divided into two types: bag type and backpack type. The hanging bag type can be carried on the back or hung on the front handle of the bicycle or on the rear shelf. Backpacks are primarily used for bike trips that require high-speed riding. All bike bags have reflective light strips for safety when riding at night.
