For hiking, camping, and short-term cross-country activities, light backpacks with a light weight and simple design should be selected, and the weight of such backpacks should not exceed 20 kg. High-altitude climbing, long-distance crossing and other activities should be carried out in heavy-duty backpacks with good performance under load. Such backpacks tend to have higher self-weight.

The volume of a backpack is often measured in "liters". Depending on the application, the volume can range from 30 litres for daily use to 80 liters for long-range expeditions. For most backpackers, a backpack with a capacity of 50 litres to 60 liters is recommended to meet the needs of general travel adventures. Some equipment, such as raincoats, warm clothes and sleeping bags, are relatively stable in size and weight. Food and fuel, on the other hand, are consumables, which decrease with the increase of activity time. The quantity of such items has a great influence on the capacity of backpacks. The standard of the backpack volume marked by different manufacturers may also be different, and these factors must be taken into consideration. When purchasing, you may wish to consult sales staff or people who are experienced in outdoor travel.

The backpack fabric needs to consider the degree of wear, the degree of waterproofing, the degree of lightness and weight of the fabric, the degree of anti-tearing, the degree of softness, and the degree of UV protection. Anti-tear fabrics are mostly grid-shaped; for backpacks that do not have waterproof function, it is necessary to match the rain cover; wear-resistant materials are mostly used at the bottom of the backpack, where the ground and rocks are most exposed. In addition, weaving tightness of backpack fabrics should also pay attention to choose.
