1. A pant-like disposable absorbent garment extending in a longitudinal direction and a lateral direction and having a longitudinal centerline and a lateral centerline, the garment having a front region defining a front waist end edge, a rear region defining a rear waist end edge, and a crotch region longitudinally between the front and rear regions, the crotch region defining two laterally opposed crotch side edges, and the garment defining a garment length extending from the front waist end edge to the rear waist end edge, the garment comprising:
a front waist panel disposed in the front region comprising:
a front panel garment-side facing layer,
a front panel body-side facing, and
one or more front panel chassis elastic members disposed between the front panel garment-side facing layer and the front panel body-side facing layer;
a rear waist panel disposed in the rear region comprising:
a rear panel garment-side facing layer,
a rear panel body-side facing layer, and
one or more rear panel chassis elastic members disposed between the rear panel garment-side facing layer and the rear panel body-side facing layer,
wherein a portion of the one or more rear panel chassis elastic members proximate the rear waist end edge are uncovered by one of the rear panel garment-side facing layer and the rear panel body-side facing layer and covered by the other of the rear panel garment-side facing material and the rear panel body-side facing material;
a rear panel secondary elastic member disposed directly overlapping, in a vertical direction perpendicular to the longitudinal direction and the lateral direction, the uncovered portion of the one or more rear panel chassis elastic members; and
an absorbent assembly disposed between the front panel and the rear panel, the absorbent assembly comprising a topsheet, a backsheet, and an absorbent body disposed between the topsheet and the backsheet,
wherein one of the rear panel garment-side facing layer and the rear panel body-side facing layer proximate the rear waist end edge is folded over the rear panel secondary elastic member, forming a rear panel fold, and overlaps the other one of the rear panel garment-side facing layer and the rear panel body-side facing layer, and
wherein the rear panel fold forms the rear waist end edge,
wherein the rear panel secondary elastic member overlaps, in the vertical direction, both the uncovered portion of the one or more rear panel chassis elastic members and the one of the rear panel garment-side facing layer and the rear panel body-side facing layer disposed adjacent the uncovered side of one or more rear panel chassis elastic members, and
wherein the one of the rear panel garment-side facing layer and the rear panel body-side facing layer proximate the rear waist end edge that is folded over the rear panel secondary elastic member forms a primary rear panel fold forming the rear waist end edge and a secondary rear panel fold such that a portion of the one of the rear panel garment-side facing layer and the rear panel body-side facing layer is disposed between the rear panel secondary elastic member and the one of the rear panel garment-side facing layer and the rear panel body-side facing layer adjacent the uncovered side of the one or more rear panel chassis elastic members, and wherein the secondary rear panel fold folds back towards the body-side and/or garment-side facing layers.
