A composite article (10) for protecting a substrate comprises a first elastomeric layer (16) that is a show surface of the composite article (10). The first elastomeric layer (16) comprises the reaction product of first isocyanate and first isocyanate-reactive components. At least one of the first components is aliphatic. The composite article (10) further comprises a second elastomeric polyurea/urethane hybrid layer (18) adhered to the first elastomeric layer (16). The second elastomeric polyurea/urethane hybrid layer (18) comprises the reaction product of second isocyanate and second isocyanate-reactive components. At least one of the second components is aromatic. Each of the elastomeric layers (16,18) has a glass transition temperature less than 0-C. The composite article (10) can further include a substrate layer adhered to the second elastomeric polyurea/urethane hybrid layer (18) opposite the first elastomeric layer (16). The composite article (10) may be a bedliner for a vehicle, such as for a truck.
