New Nylon Foldable Large Rolling Duffel Carry on Low Cost Wheeled Duffle Bag

Generally, heavy items should be placed on the top, so that the center of gravity of the backpack is higher. This way, the person carrying the backpack can straighten their waist during the journey, and some of the center of gravity should be lowered to allow their body to bend and bounce through trees or climb on bare rock walls. During climbing (rock climbing backpacks), the center of gravity of the backpack should be close to the pelvic position, which is the center point of body rotation, to prevent the weight of the backpack from shifting to their shoulders during the hiking process, The center of gravity of the back packaging can be higher and tightly attached to the back.

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.
