Load restraints are straps placed at the top of each shoulder strap of your backpack.Because of the adjustable back height of your bag (thanks to the shoulder straps), it is necessary to adjust the position of the shoulder strap in relation to the bag to limit swinging. This function is provided by these straps.To adjust them, once the bag is on your back, the belt is buckled and the tension of the shoulder straps is adjusted, simply grab the strap of each restraint over your shoulder and pull them forward until you feel the bag hug your back.To control its stability, you can shrug your shoulders a few times and take up tension if necessary.
