Adjust your bag
Before the big departure, you must adjust your bag to your body shape so that it can be fully functional and thus relieve you as much as possible by correctly distributing the weight.
The first step is to completely loosen the straps of the bag that needs to be filled.
1. Height of the shoulder straps : You must adjust the straps of the shoulder straps so that the abdominal belt falls correctly on the iliac crest (the bone that you feel at the level of the hips) and not at the height of the stomach. The straps must rest correctly on the shoulders without any pain points.
Some large volume bags have a system for varying the height of the back (Vari quick, etc.).
2. Tightening abdominal belt : The belt surrounds the pelvis. Good tightening is necessary because the abdominal belt greatly relieves the weight of the bag and will reduce the weight distributed on the shoulders.
