What Are The Tips For Using The Backpack
Before choosing a backpack, you first need to measure the length of your back upper body, that is, the distance from the protrusion of the cervical spine to the last lumbar spine. If the length of the torso is less than 45 cm, you should buy a small bag. If the torso length is between 45-52 cm, you should choose a medium-sized bag. If your torso is longer than 52 cm, you should pick a large bag.
For large backpacks with a volume of more than 50 liters, when placing items, put heavy objects that are not afraid of bumps on the lower part. After placing it, it is best that the backpack can stand alone. If there are more heavy objects, put the heavy objects evenly in the bag. And close to one side of the body, so that the overall center of gravity will not fall back.
There are skills on the shoulders of the backpack. Put the backpack at a certain height, put your shoulders into the shoulder straps, lean forward, and stand up on your legs. This is a more convenient way. If there is no high place to put it, lift the backpack with both hands, place it on one knee, face the strap, control the bag with one hand, grab the shoulder strap with the other hand and quickly turn around, so that one arm enters the shoulder strap, and then the other arm Enter.
After carrying the bag, the waist belt should be tightened so that the crotch is subjected to the heaviest force, and the chest belt should be buckled and tightened so that the backpack does not have a fall-back feeling. When walking, pull the shoulder belt with both hands to adjust between the backpack and the backpack. Lean forward slightly, so that when walking, the gravity is actually on the waist and hips, and there is no pressure on the back. In case of emergencies, the upper limbs can be flexible. When passing through rapids and steep sections without protection, the shoulder straps should be loosened, and the waist and chest straps should be opened, so that in case of danger, the bag can be separated at the fastest speed.
