1. A compound sanitary napkin adapted to be worn in a wearer'"'"'s undergarment comprising;
- an uppermost primary absorbent member having an absorbent core and a fluid pervious topsheet superposed on the absorbent core, a first transverse end and an opposite second transverse end and a first longitudinal side and an opposite second longitudinal side defining therebetween a width;
a lowermost secondary absorbent member having a fluid pervious topsheet and a fluid impervious barrier sheet joined to at least a portion of the topsheet, a first transverse end and an opposite second transverse end and a first longitudinal side and an opposite second longitudinal side defining therebetween a width, at least a portion of the primary absorbent member along or adjacent to its first transverse end is joined to at least a portion of the secondary absorbent member along or adjacent to its first transverse end at a first union means;
at least a portion of the primary absorbent member along or adjacent to its second transverse end is joined to at least a portion of the secondary absorbent member adjacent along or adjacent to its second transverse end at a second union means;
the primary absorbent member having a center portion intermediate the first and second union means;
the secondary absorbent member having a central region intermediate the first and second union means;
the center portion and the central region being unaffixed to each other and each having a respective length measured from the first union means to the second union means, wherein the center portion of the primary absorbent member has a length that is less than the length of the central region of the secondary absorbent member and the length of the central region of the secondary absorbent member is foreshortened and wherein at least a portion of the center portion of the primary absorbent member is spaced apart from the central region of the secondary absorbent member to provide a dynamic fit to the wearer.
