1. An absorbent article having a front edge, a back edge, two longitudinally extending side edges, a front waist region, a rear waist region, a crotch region extending between the front waist region and the rear waist region, a skin-facing side, and a clothing-facing side, the absorbent article comprising:
a topsheet, the topsheet being liquid pervious;
a backsheet coupled to the topsheet, the backsheet being liquid impervious;
an absorbent core disposed between the topsheet and backsheet, the absorbent core containing at least one absorbent material;
an acquisition distribution layer disposed between a bottom side of the topsheet and a top side of the absorbent core;
first and second standing leg cuffs, each standing leg cuff includes:
a base coupled to the topsheet; and
one or more elastics coupled to a top of the standing leg cuff; and
a waist barrier located on the skin-facing side of one of the front waist region or the rear waist region, the waist barrier including:
a top portion, a bottom portion, and a resilient member, the resilient member being folded to form the top portion and the bottom portion; and
a first longitudinal end region, a second longitudinal end region, and a middle region between the first and second longitudinal end regions, the top portion and the bottom portion of the waist barrier being bonded together in the first and second longitudinal end regions, and the top portion of the waist barrier being unbonded to the bottom portion of the waist barrier in the middle region;
wherein the resilient member is inherently biased such that the resilient member is compressible towards the skin-facing side to form a biasing force in a direction away from the skin-facing side whereby a cavity is formed between the top portion and the bottom portion of the waist barrier in the unbonded middle region, and
wherein the resilient member has a length in a direction transverse to the longitudinal side edges that is at least a width of the crotch region.
