A disposable absorbent incontinence diaper for wear by a user, the diaper comprising: a main part having a front area with a first front lateral longitudinal edge and a second front lateral longitudinal edge, a rear area with first rear lateral longitudinal edge and a second rear lateral longitudinal edge and a crotch area disposed between said front area and said rear area in a longitudinal direction, said crotch area resting between legs of the user, said main part also having an absorbent core; a first front side section having an inner side and an outer side; a second front side section having an inner side and an outer side; a first rear side section having an inner side and an outer side; a second rear side section having an inner side and an outer side; a first front seam disposed between and joining said first front side section to said front area proximate to said first front lateral longitudinal edge, said first front side section thereby protruding in a transverse direction past said first front lateral longitudinal edge; a second front seam disposed between and joining said second front side section to said front area proximate to said second front lateral longitudinal edge, said second front side section thereby protruding in a transverse direction past said second front lateral longitudinal edge; a first rear seam disposed between and joining said first rear side section to said rear area proximate to said first rear lateral longitudinal edge, said first rear side section thereby protruding in a transverse direction past said first rear lateral longitudinal edge; a second rear seam disposed between and joining said second rear side section to said rear area proximate to said second rear lateral longitudinal edge, said second rear side section thereby protruding in a transverse direction past said second rear lateral longitudinal edge; a first closing means attached to said first rear side section, said first closing means having first closing aids, wherein a releasable holding force generated between said first closing means and said outer side of said second rear side section is less than a closing force generated between said first closing means and said outer side of said first front side section when closing the diaper; and a second closing means attached to said second rear side section, said second closing means having second closing aids, wherein a releasable holding force generated between said second closing means and said outer side of said first rear side section is less than a closing force generated between said second closing means and said outer side of said second front side section when closing the diaper, wherein said first front side section, said main part and said first rear side section share a common first continuous outer edge defining a first leg opening, said first continuous outer edge slanting inwardly through said first front side section towards said crotch area and intersecting said first front seam before travelling into said crotch area of said main part and subsequently curving outwardly to cut through said first rear seam and slant outwardly through said first rear side section, wherein said second front side section, said main part and said second rear side section share a common second continuous outer edge defining a second leg opening, said second continuous outer edge slanting inwardly through said second front side section towards said crotch area and intersecting said second front seam before travelling into said crotch area of said main part and subsequently curving outwardly to cut through said second rear seam and slant outwardly through said second rear side section, said first and said second outer edges thereby being formed by one single respective separating process to impart an hour-glass contour to the disposable absorbent incontinence diaper.
