Use skills:

1, a large backpack with a volume of more than 50 liters. When placing items, put the heavy objects that are not afraid of bumping on the lower part. After placing, the backpack is best to stand alone. If there are many weights, put them evenly in the bag, close to the side of the body, so that the overall center of gravity will not fall back.

2. The shoulder of the backpack is skillful. It is more convenient to put the backpack at a certain height, put the shoulder into the shoulder strap, lean forward and stand on your legs. If there is no high place to put it, lift the backpack with both hands, land on one knee and face the strap. Hold the bag with one hand, and turn around quickly with the other hand to let one arm enter the strap, and then the other arm enters.

3. After carrying the bag, tighten the belt to make the crotch receive the maximum force. Fasten the chest strap and tighten it so that the backpack does not feel backward. When walking, pull the adjustment belt between the shoulder strap and the backpack with both hands, and lean forward slightly, so that when walking, the gravity is actually in the waist and crotch, and there is no pressure on the back. In an emergency, the upper limbs can be flexible.

4. When passing through the steep rapids without protection, loosen the shoulder straps and open the belts and chest straps, so that people and bags can be separated as quickly as possible in case of danger.
