摘要： A disposable absorbent pant having a front belt portion and a rear belt portion is disclosed. The front and rear belt portions are joined at side seams and the rear belt portion has a greater length than the front belt portion. A lower edge of the rear belt portion forms at least in part edges of left and right leg openings to the rear of the side seams. The rear belt portion includes first and second layers of nonwoven web material sandwiching a plurality of laterally extending and laterally pre-strained elastic strands, disposed below the side seams. A first of the plurality of elastic strands differs from a second of the plurality of elastic strands by one or more of amount of pre-strain, tensile modulus, decitex, and combinations thereof.
