1. An extensible laminate comprising:
a necked nonwoven web; and
an elastomeric sheet,
wherein the necked nonwoven web and the elastomeric sheet after lamination and prior to a cycling test, have been mechanically
stretched in the cross direction to provide an extensible laminate having a hysteresis value, measured during a first 100
percent elongation/retraction cycle of the cycling test, at least about 15 percent lower than a comparable extensible laminate
that has not been previously stretched.
