Abstract

In one embodiment, a disposable absorbent garment includes a unitary outer cover layer and first and second side seams which extend from a waist opening to a pair of leg openings. The garment includes elastomeric front and back body panels superposed on and attached to the front and back regions of the unitary outer cover layer. The front and back body panels each comprise an elastomeric film laminate that extend longitudinally along the respective outer cover layer side edges a distance at least 50% of the first side seam length and at least 50% of the second side seam length. The elastomeric film laminate can comprise an elastomeric film layer and a nonwoven layer, and a bodyside surface of the elastomeric film layer is directly adhered to the nonwoven layer, and a garment-side surface of the elastomeric film layer is directly adhered to the unitary outer cover layer.
