The backpacks suitable for men and women are not consistent because the upper body of boys is longer, while the upper body of girls is shorter but the legs are longer. Choose your own suitable backpack carefully. When loading, the weight of boys should be placed higher because the center of gravity of boys is close to the chest, while the weight of girls is lower and close to the abdomen. The weight of heavy items should be as close to the back as possible, so that the weight is higher than the waist.

Travel bags are divided into hiking bags and daily urban or short distance travel bags, and their functions and purposes are very different. Mountaineering bags can be divided into large bags and small bags. There are two types of large bags: external and internal. Due to the inconvenience of traveling in the mountains and forests, it is generally recommended to use internal travel bags. Taking Siguniang Mountain hiking in Sichuan as an example, it is recommended that men use a 70-80 liter travel bag and women use a 40-50 liter travel bag. It is best to have a detachable top or waist bag with your travel bag. After arriving at the campsite, you can put your commonly used items in the top or waist bag, leave the large bag at the campsite, and go light.
