Abstract
A disposable absorbent garment can include a waistband assembly that is configured to be worn about a waist of a subject, and an absorbent panel assembly having first and second ends that are coupled to the waistband assembly. The absorbent panel assembly can include a liquid-pervious body-side layer, a liquid impervious external layer, and an absorbent core positioned between the body-side and external layers. At least one of the absorbent panel assembly or the waistband assembly includes a contraction region, such as near the absorbent core, that is configured to be extensible and retractable along a longitudinal axis of the absorbent core. The longitudinal axis can be substantially parallel to a vertical or height axis of a wearer when the absorbent garment is worn by an upright or standing individual.
