Abstract
A feature of this invention is the raised longitudinal hydrophobic edges or edge members in combination with the raised central member. Since the raised central member captures the body fluids close to the source of fluid discharge it contains the body fluids in the central portion of the napkin. In addition, the raised hydrophobic longitudinal edges or edge members prevent fluid from wicking through to the undergarment of the user.

An absorbent article comprising:
- a. an elongate napkin base having a body facing surface, a garment facing surface, a front lateral end, a rear lateral end, a raised central member, a first fibrous raised hydrophobic longitudinal edge and a second fibrous raised hydrophobic longitudinal edge;
