Abstract

An absorbent article ( 10, 110, 210, 310 ) can include a chassis ( 11 ) including an absorbent body ( 34 ). The chassis ( 11 ) can include a body facing surface ( 19 ). The absorbent article ( 10, 110, 210, 310 ) can also include a waist containment member ( 54, 154, 254 ). The waist containment member ( 54, 154, 254 ) can include a proximal portion ( 76 ) coupled to the body facing surface ( 19 ) of the chassis ( 11 ) and a distal portion ( 78 ) that includes a free edge ( 88 ). The distal portion ( 78 ) can be free to move with respect to the chassis ( 11 ) when the absorbent article ( 10, 110, 210, 310 ) is in a relaxed configuration. The free edge ( 88 ) can be about 50.0 millimeters or less from the rear waist edge ( 24 ) of the absorbent article ( 10, 110, 210, 310 ) when the absorbent article ( 10, 110, 210, 310 ) is in the stretched, laid-flat configuration.
