1. An absorbent garment having longitudinal and transverse axes, the garment comprising:

  • a three-dimensional pant body defining a waist opening, two leg openings, and a crotch region;

    a containment trough having a liquid impermeable base portion bonded to the crotch region and integral retaining walls transversely outward from the base portion, each retaining wall .;

    being liquid impermeable and freestanding from the pant body;

    elastic members operatively joined to the retaining walls to define freestanding elasticized flaps, each flap comprising on of the liquid impermeable walls and having an inwardly-directed face that is adapted to transport liquid in the plane of the inwardly directed face as defined by a first Wicking Value greater than zero;

    an absorbent structure disposed between the flaps, the absorbent structure having upper and lower surfaces, longitudinally spaced end edges, and side edges extending between the end edges; and

    a liner bonded to the containment trough and formed of a liquid permeable material that is adapted to transport liquid in the plane of the liquid permeable material as defined by a second Wicking Value, the liner covering the upper surface, wrapped over the side edges, and covering at least part of the lower surface of the absorbent structure;

    wherein the second Wicking Value is at least 2 times greater than the first Wicking Value on a gram per gram basis.
