In a disposable absorbent garment, an absorbent structure includes liquid absorbing material comprising an upper layer comprising preferably softwood fibers and having a density from about 0.03 to about 0.14 g/cc, a lower layer comprising preferably hardwood fibers, formed substantially separately from and underlying at least a portion of the upper layer, the second layer having top and bottom surfaces, a density from about 0.14 to about 0.3 g/cc, a total void volume greater than about 80%, an average pore size distribution generally less than the average pore size distribution of the upper layer. There is an overlap in the pore size distributions of the upper and lower layers such that the smallest pores in the upper layer are smaller than the largest pores in the lower layer and front and rear fluid storage pouches, preferably spaced from one another at the front one-third and rear one-third of the absorbent structure, respectively, each pouch comprise superabsorbent material disposed in a hydrophilic web. The spaced fluid storage pouches are preferably located underlying the bottom surface of the lower layer so that the absorbent structure is substantially free of superabsorbent material in the middle one-third thereof.

In a disposable absorbent garment, an absorbent structure having opposed longitudinal ends, a central crotch portion and including a body-facing sheet, a backing sheet and liquid absorbing material therebetween, said liquid absorbing material comprising: a first layer consisting essentially of cellulosic fibers and having a density from about 0.03 to about 0.14 g/cc and underlying said facing sheet, said first layer having top and bottom surfaces; a second layer consisting essentially of cellulosic fibers, formed substantially separately from and underlying at least a portion of said first layer, said second layer having top and bottom surfaces, a density from about 0.14 to about 0.3 g/cc, a total void volume greater than about 80%,, an average pore size distribution generally less than the average pore size distribution of said first layer and wherein there is an overlap in the pore size distributions of said first and second layers such that the smallest pores in said first layer are smaller than the largest pores in said second layer; and front and rear fluid storage pouches comprising superabsorbent material disposed in a hydrophilic web, said pouches being located underlying said first layer and spaced from one another at said opposed longitudinal ends, respectively of said absorbent structure.
