An incontinence underwear including a crotch area hosting a stitching, a first layer, a second layer, a third layer, a fourth layer, a fifth layer, a sixth layer, and a seventh layer, wherein the first layer is innermost, wherein the seventh layer is outermost, wherein the second layer extends between the first layer and the third layer, wherein the fourth layer extends between the third layer and the fifth layer, wherein the sixth layer extends between the fifth layer and the seventh layer, wherein the stitching extends through the first layer, the second layer, the sixth layer, and the seventh layer, wherein the stitching avoids extending through the third layer, the fourth layer, and the fifth layer, wherein the second layer is bonded or adhered to the third layer.

Claims (41)

1. An incontinence underwear further comprising:

a crotch area;

a first leg opening and a second leg opening;

the crotch area further comprising:

a first layer that is an innermost layer of the incontinence underwear;

a second layer comprising an adhesive material;

a fourth layer comprising an absorbent material;

a fifth layer comprising a water proof material;

a sixth layer;

and a seventh layer; and

a stitching extending through the first layer, the second layer, the sixth layer, and the seventh layer, and wherein the stitching does not extend through the third layer, the fourth layer, and the fifth layer;

wherein the second layer is positioned between the first layer and the third layer, wherein the fourth layer is positioned between the third layer and the fifth layer, wherein the sixth layer is positioned between the fifth layer and the seventh layer.

2. The incontinence underwear of claim 1 , wherein the second layer includes a bonding tape and wherein an additional adhesive material on a second side, wherein the second layer is adhered to the first layer via the additional adhesive material.

3. The incontinence underwear of claim 2 , wherein the adhesive material and the additional adhesive material comprise the same adhesive.

a third layer comprising a moisture wicking material, the third layer being adhered to the second layer via the adhesive material for aiding in securing the third layer in position relative to the first layer;

a fourth layer comprising an absorbent material;

a fifth layer comprising a water proof material;

a sixth layer;

and a seventh layer; and

a stitching extending through the first layer, the second layer, the sixth layer, and the seventh layer, and wherein the stitching does not extend through the third layer, the fourth layer, and the fifth layer;

wherein the second layer is positioned between the first layer and the third layer, wherein the fourth layer is positioned between the third layer and the fifth layer, wherein the sixth layer is positioned between the fifth layer and the seventh layer,
