1. An absorbent article comprising:
a chassis extending in a longitudinal direction and having a longitudinal centerline and a lateral direction and having a lateral centerline, the chassis having a front waist region including a front waist edge, a rear waist region including a rear waist edge, and a crotch region extending between the front waist region and the rear waist region, and the chassis comprising:
a garment facing outer cover,
a body facing liner,
an absorbent body disposed between the garment facing outer cover and the body facing liner;
a pair of containment flaps extending between the front waist region and the rear waist region, each of the pair of containment flaps having distal edges and proximal edges; and
a secondary liner sheet having a rear sheet edge, a front sheet edge, and longitudinally extending sheet side edges,
wherein the secondary liner sheet is attached to each of the containment flaps along flap attachment regions disposed proximate the distal edges, each of the flap attachment regions having a flap attachment region length and a flap attachment region height,
wherein each of the flap attachment regions has a flap attachment region length, and
wherein each of the flap attachment region lengths is between about 8% and about 16% of a total length of the absorbent article; and
wherein the secondary liner is attached to the body-facing liner through a liner attachment region and has a rear un-bonded region extending between the liner attachment region and the rear sheet edge, the rear un-bonded region has a rear un-bonded region length, and
wherein the rear un-bonded region length is greater than the flap attachment height, the flap attachment height being defined as a distance between one of the first longitudinally extending attachment regions and an edge of a flap attachment region most proximate a distal edge of a containment flap.
