Abstract
An absorbent article is provided including a backsheet, a topsheet and an absorbent core disposed therebetween. The diaper includes large rectangular fasteners that stretch in only one direction. At least one longitudinally extending, elasticized inner leg gather is disposed with the topsheet. The inner leg gather includes at least one elastic member for distributing elastic contractile forces. The inner leg gather is joined to the topsheet along a front tackdown zone and a back tackdown zone. The elastic members and tackdown zones extend in a manner sufficient to provide enhanced fit, functionality and waste containment. The unidirectional stretch fasteners and leg gathers are sized in relationship to each other to enable a complete encircling of each leg to form a better leg gasket for waste containment and fit.
