Abstract
Abstract A prefolded disposable diaper of the wing fold style and having a transverse fold in which each of the side edges adjacent the transverse fold are fastened securely to each other a predetermined distance from the transverse fold whereby the length of each of the side edges is made effectively shorter than the normal full length dimension of the diaper. These shortened side edges provide a closer fit around the child''s leg at the interior thigh area. A downwardly depending fin formed at the side edges by the edge securement also defines a side pocket on each side useful as an additional entrapment area for excrement.
