Abstract

A disposable absorbent article for wearing in an undergarment, such as a sanitary napkin, pantiliner, or incontinence pad is described. The absorbent article comprises a topsheet, a backsheet, an absorbent core, and a stiffening feature. The stiffening feature places the absorbent article in an initially stiffened during placement of the article in an undergarment. After the article is subjected to the forces exerted by the body of the wearer, the stiffening feature no longer provides an increased initial stiffness and the article becomes more flexible.
