Leak resistant disposable diaper or incontinent brief particularly suitable for adult wear. The garment is from about two or three times as long as it is wide so that the sides of the wearer are not covered. Each end of the garment has a relatively long flap (14, 16) formed by extensions of the envelope retaining the pad of absorbent material. The absorbent pad itself (4) is trimmed generally in the form of an hourglass (19). However, the cutout side portions are located forward of the transverse centerline of the pad. Also, the forward edge of the cutouts does not expand as rapidly to full width as does the back edge to allow a better fit in the groin area. Elastic strips (10) are located adjacent to the edges of the pad and run the full length of the product. Relatively long attachment straps (12, 12') are anchored to the back flap and form the means of holding the garment on the wearer. The adhesive on the free ends of the attachment straps is preferably one that is high in shear strength but low in peel strength in reference to the thermoplastic moisture impervious backsheet of the diaper. This allows the straps to be easily removed and reattached if desired, but provides a firm grip while the garment is being worn.
