Absorbent article such as disposable diapers, incontinent briefs, diaper holders and the like, that have a unique elastic waist feature that improves the dynamic fit of the elasticized waistband as well as the containment characteristics of the absorbent article.

The elasticized waistband comprises a shaping panel zone; a waistline panel zone; and a predisposed, resilient, waistband flexural hinge zone joining the shaping panel zone and the waistline panel zone. The waistband flexural hinge zone is predisposed to allow the panel zones to flexurally bend about a defined axis or zone and is resilient to provide a restoring force/moment that returns the panel zones to their preceeding in-use configuration, especially when the elasticized waistband has been pretensioned by a closure system. The closure system dynamically creates/maintains lateral tension through the elasticized waistba…
