land areas in the laminate in areas free of the three-dimensional elements;
wherein, in the land areas, the laminate has a first basis weight, according to the Micro-CT Test; and
increased permeability regions formed in the laminate adjacent to at least some of the three-dimensional elements and intermediate at least some of the land areas and at least some of the three-dimensional elements;
wherein the increased permeability regions have a second basis weight in the range of 50% to 5% less than the first basis weight of the land areas, according to the Micro-CT Test.
