Large backpacks, used to carry loads over 10 kg, usually offload the largest part (up to about 90%) of their weight onto padded [[hip]] belts, leaving the shoulder straps mainly for stabilising the load. This improves the potential to carry heavy loads, as the hips are stronger than the shoulders, and also increases agility and balance, since the load rides nearer the person's own center of mass. | ||
