The disclosure relates to an absorbent undergarment comprising a fabric layer defining a waist opening, two leg openings and a crotch region between the leg openings, the absorbent undergarment further comprising an absorbent pad covering at least part of said crotch region and being permanently attached to the fabric layer. The absorbent pad comprises at least one absorbent layer and a skin-facing layer. At least one layer, selected from said absorbent layer, said skin-facing layer or an optionally present wicking layer, comprises naturally-derived fibers comprising a polycarboxylic acid. The polycarboxylic acid has at least one carboxyl group covalently bound to the naturally-derived fibers and at least one free carboxyl group.

The present invention relates to a novel disposable undergarment device. The device is designed to ensure accidental body leaks are absorbed prior to staining clothing and causing an embarrassing situation. The device comprises absorbent, disposable boxer briefs, standard briefs, and/or female undergarments that can be worn during athletic events and other activities. The sides of the undergarments are expandable and attached via two-sided tape, as well as an elastic waistband. The inside of the undergarments comprises an absorbent padding which is constructed using a fluffy, paper-like material, such as cellulose fiber, which is designed to enhance the fit of the padding and help stop leaks.

A garment is provided, the garment comprising a base fabric layer having an inner surface and an outer surface, the base fabric layer further having on the inner surface, an absorption region and a non-absorption region. In a particular implementation, the non-absorption region is configured to be in contact with the skin of a wearer of the garment. The garment further includes a moisture prevention insert that includes a moisture resistance layer in contact with the absorption region of the base fabric layer, wherein the moisture resistance layer includes at least two sub layers, each sub layer having a thermoplastic polyurethane coating; a fluid absorption layer configured in contact with the moisture resistance layer; and a mesh layer configured to have one surface thereof in contact with the fluid absorption layer and an opposing surface thereof in contact with the skin of the wearer.

A cover nonwoven fabric covers a back surface of an inner member from between a front side outer member and the inner member to between a back side outer member and the inner member. The cover nonwoven fabric extends from a back surface side of a base portion of one side gather to a back surface side of a base portion of the other side gather. The cover nonwoven fabric has holes penetrating the front and back surfaces at intervals from between the front side outer and inner members to between the back side outer and inner members. The side edges of the cover nonwoven fabric are located at the positions same as the side edges of the narrowest part of the absorber in the width direction or on the center side in the width direction with respect to the side edges of the narrowest part.

An absorbent article (10, 110, 210, 310, 410) can include a waist containment member (54) and an absorbent body (34, 134, 234, 334, 434). The waist containment member (54) can include a proximal portion (76) and a distal portion (78) configured to freely move with respect to the chassis (11) when the absorbent article (10, 110, 210, 310, 410) is in a relaxed configuration to provide a containment pocket (82). The absorbent body (34, 134, 234, 334, 434) can be configured to provide improved access for exudates into the containment pocket (82) of the waist containment member (54).
