Abstract
The disclosure relates to absorbent articles having a front belt and a rear belt, each comprising a central zone and first and second peripheral zones, the zones extending substantially in transverse direction of the absorbent article. The at least first belt provides improved fit in the low motion zone of a wearer while being able to adapt easily to the motion of the wearer outside the low motion zone.
