Abstract
Abstract A sanitary napkin with an absorbent batt which has been folded upon itself along each longitudinal edge and then folded inwardly to provide a three layer absorbent batt. The sanitary napkin has a fluid permeable wrap which overlies each outer and inner fold and terminates at the outer edges of the third layer. A fluid impermeable baffle is positioned between the multiple layers of absorbent and the wrap except on the top, i.e., body facing surface of the absorbent batt.
