1. A method for manufacturing a breathable elastic laminate, the method comprising:
aperturing an elastic film to create an apertured elastic film with a pattern, the pattern comprising
a plurality of first lanes extending in a machine direction, each of the plurality of first lanes comprising a plurality of apertures, and
a plurality of second lanes extending in the machine direction, each of the plurality of second lanes devoid of apertures and having a width greater than twice the width of one of the plurality of apertures in the first lanes,
the plurality of second lanes alternating with the plurality of first lanes in a cross direction substantially orthogonal to the machine direction;

stretching the apertured elastic film in the machine direction to activate the apertured elastic film in the machine direction; and
bonding a first side of the activated apertured elastic film with the activated apertured elastic film under tension to a nonwoven web to create a breathable elastic laminate, after the elastic film is apertured,
wherein the plurality of apertures are three-dimensional apertures.
