## Abstract

An article including a front region, a back region, and a chassis. The chassis may include an absorbent core having a front end edge and a back end edge. The front region and the back region may extend laterally outward beyond side edges of the chassis. The front region and the back region may abut to form a first seam and a second seam. At least one of the front region and the back region may include an elastic member. A first outer nonwoven layer of the front region and a second outer nonwoven layer of the back region may be folded to form an upper edge in the front and back regions such that a distal end of each of the first and second outer nonwoven layer may be disposed between the upper edge and the front and back end edges of the absorbent core, respectively.

## Claims

### Claim 1

A pull-on wearable article comprising:
a front region;
a back region opposite the front region;
a crotch region disposed between the front region and the back region, wherein the crotch region comprises two opposing longitudinal edges;
a chassis comprising an absorbent core extending from the front region to the back region, the absorbent core comprising a front end edge and a back end edge;
wherein the front region extends laterally outward beyond side edges of the chassis and the back region extends laterally outward beyond side edges of the chassis;
wherein the front region comprises a first front edge and a second front edge and the back region comprises a first back edge and a second back edge;
wherein a portion of the front region and a portion of the back region abut to form a first seam and a second seam such that the front region and the back region are configured to form a continuous belt, a first leg opening, and a second leg opening;
wherein at least one of the front region and the back region comprise an elastic member;
a folded continuous belt portion comprising a fold and including at least a first outer nonwoven layer of the front region and at least a second outer nonwoven layer of the back region, wherein the folded continuous belt portion extends about a circumference of the continuous belt when positioned on the wearer, and wherein the folded continuous belt portion comprises an upper edge in the front and back regions such that a distal end of each of the first outer nonwoven layer and the second outer nonwoven layer is disposed between the upper edge and the front and back end edges of the absorbent core, respectively; and
wherein the folded continuous belt comprises a first portion extending laterally between the first seam and the second seam and extending longitudinally between the upper edge and the distal end of the first outer nonwoven layer, the first portion has a first longitudinal distance measured from the upper edge to the distal end of the first outer nonwoven layer;
wherein the folded continuous belt comprises a second portion extending laterally between the first seam and the second seam and extending longitudinally between the upper edge and the distal end of the second outer nonwoven layer, the second portion has a second longitudinal distance;
wherein each of the first front edge, the second front edge, the first back edge, and the second back edge extend in a longitudinal direction perpendicular to at least one of the distal end of the first outer nonwoven layer and the distal end of the second outer nonwoven layer;
wherein the first longitudinal distance is substantially uniform relative to the second longitudinal distance;
wherein the first seam comprises discrete spaced bonds extending in the longitudinal direction from the first leg opening to the upper edge;
wherein the second seam comprises discrete spaced bonds extending in the longitudinal direction from the second leg opening to the upper edge.

### Claim 2 (depends on 1)

The pull-on wearable article of claim 1, wherein the distal end of each of the first outer nonwoven layer and the second outer nonwoven layer is disposed on at least one of a garment facing surface and a wearer facing surface.

### Claim 3 (depends on 1)

The pull-on wearable article of claim 1, wherein the first longitudinal distance is about 2.0 cm.

### Claim 4 (depends on 1)

The pull-on wearable article of claim 1, further comprising a graphic disposed on a wearer facing surface of the wearable absorbent article.

### Claim 5 (depends on 1)

The pull-on wearable article of claim 1, wherein the elastic member comprises one or more strands.
