A disposable absorbent article comprising: a central body including an absorbent core, and a front end edge and a rear end edge spaced longitudinally from the front end edge, said end edges defining, at least partially, a front waist portion and a rear waist portion spaced longitudinally from the front waist portion, wherein the absorbent core extends longitudinally between the front waist portion and the rear waist portion and through a lateral centerline of the article that is spaced longitudinally from each of the front waist portion and the rear waist portion, and wherein a longitudinal centerline of the article extends longitudinally through the absorbent core and through the end edges bisecting the lateral centerline; first liquid pervious topsheet, wherein said absorbent core is disposed between the first liquid pervious topsheet and a liquid impervious backsheet; a second topsheet extending across a second topsheet gap that is narrower than a backsheet gap wherein a difference between the second topsheet gap and the backsheet gap results in formation of a reservoir between the absorbent core and a wearer, the reservoir adapted to capture bodily exudates, wherein at least a portion of the reservoir is disposed between the first liquid pervious topsheet and the second topsheet; and a pair of flexible leg wraps extending outwardly from and alongside edges of the absorbent core, the leg wraps each including a plurality of spaced-apart elastic strands separated from the absorbent core by an inelastic zone, wherein the leg wraps and the absorbent core form the reservoir and a plurality of fluid dams are defined at least in part by the plurality of elastic strands during use of the absorbent article, with each fluid dam capable of capturing a volume of liquid waste from passing between the leg wrap and the wearer; and wherein said second topsheet spans laterally between said leg wraps and across said reservoir, said second topsheet being spaced above said first topsheet and said absorbent core, wherein a void is provided above said absorbent core between said first topsheet and said second topsheet; and wherein said first topsheet is disposed between said second topsheet and said absorbent core and said reservoir is disposed above said first topsheet; and wherein the lateral centerline of the article extends laterally through the flexible leg wraps, the second top sheet extending a longitudinal length from the lateral centerline toward the front waist portion and a longitudinal length toward the rear waist portion, and the second topsheet being disposed over a central part of the absorbent core that is spaced longitudinally from the waist portions and disposed about the lateral centerline.
