A nonwoven laminate having a SMS structure is hydraulically treated by particular process parameters to improve softness and tactile feel. The nonwoven laminate may also be imparted with one or more regular aperture patterns by additional hydraulic treatment processes, where the initial hydraulic treatment provides for improved aperture definition.
