The present invention provides a composite elastic necked-bonded material including at least one necked material joined to at least one elastic sheet. The composite elastic necked-bonded material is stretchable in a direction generally parallel to the direction of constriction or necking of the necked material. Also disclosed is a method of producing a composite elastic necked-bonded material by extruding a film of substantially molten elastomer through a die tip; depositing the extruded elastomeric film onto a tensioned, necked material within from about 0.1 to about 1 second of exiting the die tip to form a multilayer material; and then immediately applying pressure to the multilayer material to bond the tensioned, necked material to the elastomeric film.
