The laminate comprises a middle layer of a padding and top and bottom layer comprising a sheet of water impermeable, moisture-vapor-permeable film bonded to the middle layer and wherein at least one outer surface of the top or bottom layer is provided with a pressure-sensitive biocompatible adhesive. Preferably the top and bottom layers comprise a composite of (a) a flexible, first sheet of hydrophobic material; and (b) a continuous hydrophilic sheet attached to or penetrating the first sheet, and forming a contamination barrier. The composite is useful in diverse applications such as a padding under orthopedic casts.
