Abstract
A three-dimensionally hourglass-shaped sanitary napkin with a cellulose fluff insert for absorption that is outwardly bulging on the baffle side to create a thicker region near the center of the sanitary napkin. The baffle or fluid-impervious layer wraps around the absorbent cellulose fluff insert to form a well thereby maintaining fluid within its borders to afford increased protection from fluid leakage.
