Abstract

An absorbent article (10) has a longitudinal direction (26) and a lateral direction (24). The article includes a backsheet layer (30), a liquid-permeable topsheet layer (28), and an absorbent body (32) sandwiched between the backsheet layer (30) and topsheet layer (28). A surge management member (46) is joined between the topsheet layer (28) and the absorbent body (32), and the surge management member (46) includes at least a first nonwoven fabric layer (52). In particular aspects, the article (10) can be bent around a wearer's body contours with a reduced tendency to form a transverse channel crease (76) along the cross-direction of the surge management member, particularly when the surge member (46) is curved through the wearer's crotch region. In further aspects, the article (10) can be bent around a predetermined radius of curvature substantially without forming, within the surge management member (46), a severe channel crease (76) that extends over a significant portion of a corresponding lateral width (78) of the surge management member (46).
