A stretch laminate for a wearable article, comprising an outward-facing layer, a wearer-facing layer, and an elastic material sandwiched between the outward-facing layer and the wearer-facing layer, the elastic material having been pre-strained by a pre-strain percentage along a stretch direction during manufacture of the laminate, such that when the stretch laminate is in a relaxed condition the outward-facing layer and the wearer-facing layer are gathered along the stretch direction, wherein the outward-facing layer is formed of a section of nonwoven web material comprising an accumulation of filaments and has an inner surface and an outer surface, the outer surface comprising an ordered arrangement of zones each zone comprising an attenuated region adjacent to a build-up region, wherein the attenuated region has a first basis weight and the build-up region has a second basis weight, wherein the first basis weight is less than the second basis weight, the difference in basis weight corresponding to disposition of the filaments according to the ordered arrangement, wherein the outward-facing layer comprises a first area and a second area, the first area being occupied by the ordered arrangement of zones and the second area being distinguishable from the first area by an absence of an attenuated region over a continuous surface area of the outward-facing layer in its ungathered condition, the continuous surface area being equal to or greater than approximately 4 cm2 and having no dimension in the x-y plane smaller than approximately 1 cm, the second area being delineated from the first area by a perimeter demarking a discontinuity or interruption in the arrangement of zones; and wherein the outward-facing layer is bonded about the elastic material to the wearer-facing layer in the second area by ultrasonic bonding.
