1. An absorbent article including front region, a crotch region, and a rear region, the article having a first side edge and a second side edge and further comprising:
a first elasticated waist panel disposed in the front region;
a second elasticated waist panel disposed in the rear region and spaced from the first elasticated waist panel; and
an absorbent panel comprising an outer cover, a liner, and an absorbent body disposed between the outer cover and the liner, the absorbent panel spanning between and connecting the first elasticated waist panel and the second elasticated waist panel,
wherein one of the first elasticated waist panel and the second elasticated waist panel comprises:
a first layer of material;
a second layer of material; and
an elastomeric strand extending in a lateral direction in a straight manner through the first elasticated waist panel or the second elasticated waist panel and disposed between the first layer of material and the second layer of material;
wherein the first layer of material and the second layer of material are bonded together by a plurality of bonds, the elastomeric strand being un-bonded to the first layer of material or the second layer of material by the plurality of bonds, the plurality of bonds being arranged in bond groupings aligned in bond grouping rows, each bond grouping comprising a plurality of bonds with each bond of the plurality of bonds spaced from adjacent bonds of a bond grouping a distance less than an un-tensioned diameter of the elastomeric strand, and with the elastomeric strand extending completely between a portion of a first bond facing the elastomeric strand and a portion of a second bond facing the elastomeric strand, the first bond and the second bond being part of a first bond grouping,
wherein the first bond grouping is spaced from bond groupings longitudinally above and below the first bond grouping a longitudinal distance greater than the un-tensioned diameter of the elastomeric strand, and
wherein a portion of a longitudinal extent of a second bond grouping overlaps a portion of a longitudinal extent of the first bond grouping in the lateral direction, the second bond grouping disposed in a bond grouping row longitudinally adjacent to the bond grouping row containing the first bond grouping.
