Abstract
An absorbent article, such as a sanitary napkin, has an absorbent and a substantially non-absorbent resilient layer adjacent to the absorbent. The absorbent is sufficiently stiff to resist twisting of the absorbent article during use. The resilient layer is sufficiently resilient to resist bunching during use. As a result, the absorbent article resists both twisting and bunching. The absorbent article has zones which vary in caliper, stiffness and absorbency. A central absorbent zone is thickest in caliper, more absorbent than the other zones and is stiffer than the other zones. An adjacent zone is less thick in caliper, less absorbent and less stiff. A peripheral zone, located near the outer side edges, is least thick in caliper, least absorbent and least stiff.
