The best backpack is the one that fits best. To find out what size backpack to choose, you need to measure the length of your back.
How to determine the right backpack size?
This one will require a soft tape measure and the help of a friend.
From the 7th vertebra (that's the one that sticks out a little) to the top of the hip bone.
In this way, you will find out the approximate back size, according to which you should choose a backpack.
Proper weight distribution in the backpack
Before putting on the backpack:
1. The weight in the backpack should be placed so that the heaviest things are closest to the back, in the middle of the backpack , not at the bottom.
2. All external straps holding the contents of the backpack in place must be tightened.
After putting on the backpack:
1. the hip belt should be tightened first - the top of the hip belt should be placed on the top of the hip bone.
2. then you need to tighten the shoulder straps so that the shoulder straps fit the shoulders and there is no gap. Shoulder straps should not be oppressive.
3. then the chest strap that connects the shoulder straps (so that the shoulders do not move away, but are not pressed either)
4. tighten the backpack fasteners at the top so that the center of gravity is closer to the back, but not too tight and does not put a strain on the shoulders. (they prevent the bag from pulling backwards, ensuring a correct center of gravity)
5. When carrying a backpack, most of the weight (60-70%) should be on the hips, not on the shoulders.
During the hike, the backpack straps readjust to diversify the load, transfer the weight more to the hips, less to the shoulders, or vice versa.
Make carrying a backpack comfortable!
