Abstract
A disposable absorbent article comprising an absorbent assembly comprising an absorbent core. The chassis may also comprise a water-impermeable backsheet and laterally opposing side flaps. Each of the side flaps may have a longitudinally extending first elastic gathering member attached at or adjacent to its proximal edge. The chassis may also comprise a second elastic gathering member attached at or adjacent the side edge of the chassis. The chassis may further comprise a first activation pattern in the front waist region and/or the back waist region, but the crotch region of the chassis may not be activated or may, alternatively, comprise a second activation pattern which is different from the first activation pattern. The article may further comprise at least one abdominal stretch panel attached to the interior surface or the exterior surface of the chassis in the front waist region or the back waist region. The abdominal stretch panel may provide a circumferential contractive force around the waist opening when the chassis is stretched circumferentially.
