Abstract: The absorbent pad has a first layer, a second layer, and a third layer. Each layer of the pad has a liquid impervious back sheet. The backsheet or outer layer, which faces away from the wearer when the absorbent article is secured to the wearer, is composed of a moisture-impervious, flexible material. Further, each layer has a moisture pervious inner layer and an absorbent core positioned in between the inner layer and back sheet. The layers are coupled to each other via an adhesive. They can be removed by grasping a tab placed on each layer and pulling the layer away from the unsoiled layers.
