A hydro-enlarged apertured nonwoven web, comprising: a plurality of fibers; a plurality of bond points securing the plurality of fibers to one another to define a nonwoven web; a first surface defining a planar top to the nonwoven web; a second surface defining a planar bottom to the nonwoven web; wherein the second surface is separated from the first surface by a first distance defining a loft; a plurality of apertures extending through the nonwoven web from the first surface to the second surface; wherein the plurality of apertures is formed by spraying a fluid against an unapertured precursor web, causing a plurality of pins disposed on a pinned roller to punch through the unapertured precursor web; wherein the unapertured precursor web has a third surface defining a planar top; wherein the unapertured precursor web has a fourth surface defining a planar bottom; wherein the third surface is separated from the fourth surface by a second distance defining a precursor loft; wherein the loft is greater than the precursor loft by a loft increase within a range of 50-110%.
