The sanitary napkin preferably has a caliper at the point of maximum amplitude of the hump that is greater than twice the caliper of the surrounding regions. The hump preferably has a caliper of at least about 0.15 inch (about 3.5-4 millimeters). The longitudinal central region of the sanitary napkin preferably has a flexure-resistance that is greater than that of the surrounding regions.
