Abstract An apertured laminate web which may be used as a topsheet on a disposable absorbent article, such as a diaper. The laminate web is formed of a liquid pervious first material and a liquid pervious second material attached to the first material. The first material has an effective open area of at least about 10 percent and a plurality of apertures with an effective size of at least than 0.2 square millimeters. The second material has an effective open area of at least about 10 percent and a plurality of apertures with an effective size of at least 0.2 square millimeters. The apertures of the second material are aligned with the apertures of the first material. The second material preferably has a hydrophilicity which is greater than the hydrophilicity of the first material.
