attaching the left and right elastic bands to the respective left and right lateral edges of the gusset to couple the layer of absorbent material and the layer of waterproof material to the main body.

9. The method of claim 8 , further comprising attaching the left and right elastic bands to the main body along the respective left and right lateral edges of the gusset laterally outwardly of where the left and right elastic bands overlap the respective left and right lateral edges of the layer of absorbent material.

10. The method of claim 8 , further comprising:

providing a layer of liner material sized and shaped to fit on the gusset and having left and right lateral edges configured to extend alongside the respective left and right lateral edges of the gusset;
