Material
Ordinary backpack fabrics are generally made of simple and lightweight fabrics, or some other fabrics that meet the public's aesthetics and needs. But the fabrics of mountaineering bags are relatively rigorous. Mountaineering bags are used in complex areas such as mountains and forests, and face more wind and rain, so waterproof and wear resistance are extremely important in the selection of fabrics. Therefore, the material used for mountaineering bags needs to be thick and wear-resistant nylon with waterproof coating, and seamless waterproof zippers are used to absorb high-strength engineering assembly buckles.
Carrying system
As a sport, mountaineering requires carrying a lot of items and ensuring the comfort of carrying, so mountaineering bags should focus on the carrying system. A reasonable carrying system needs to be in line with human mechanics and sweat dissipation design, as well as whether there is a carrying frame inside, and the backpack straps, abdominal belts, etc. should be considered wide and thick designs, and the waist needs to be equipped with a waist pad. These designs can reduce the discomfort caused by the heavy weight of the backpack. However, you don’t need to consider too much about the carrying system of an ordinary backpack, just ensure the comfort of daily use.
Overall function
Generally, a backpack only needs to consider the compartment storage, which can store different items for easy access. However, a mountaineering bag should consider the internal compartment storage, pay attention to the separation of dry and wet, and set up an external hanging system on the outside, which can better hang some mountaineering supplies.
