Abstract

Abstract Sanitary napkins are disclosed which include at least one flap (10) having a portion that may be expanded longitudinally for permitting the flap (10) to expand when folded over a side of an undergarment (25). This enables the flap (10) to fold outwardly to the back of the undergarment (25) and conform to the contour along the curved line of the crotch. Thus, an improved sanitary product is provided that provides side-protection along the entire longitudinal edges of the napkin.
