Abstract
Abstract An anatomically form-fitting, self-adjusting disposable garment with a resiliently stretchable outer cover (20), absorbent structure (22) comprising an absorbent composite (38), a bodyside liner (42) and a liquid impermeable barrier (44), disposed within the outer cover (20) which is provided with fixed position point-to-point fasteners (70) (72) (74) (76). The bodyside liner (42) is bonded to the stretchable outer cover (20) while the stretchable outer cover (20) is in a stretched condition thereby not inhibiting its stretchability.
