Durable and reusable incontinent underpads comprise 4-layer fabrics, incorporating a first layer (10) of woven or knit fabric, a second layer (12) of non-woven felt, a third layer (14) of polyurethane film, and a fourth layer (16) of woven or knit fabric. The first and second layers are quilted together to form a fluid absorbing portion for the underpad. The third and fourth layers are laminated together with a urethane adhesive to form a leakage preventing portion for the pad. The second and third layers are also laminated together with the urethane adhesive.
