ABSTRACT:
A flexible, breathable, non-linting, composite is provided. The laminate comprises a middle layer of a padding and a top and bottom layer comprising a sheet of porous water impermeable, moisture-vapor-permeable film bonded to the middle layer. Preferably the top and bottom layers comprise (a) a flexible, first sheet of hydrophobic material having a moisture vapor transmission rate exceeding 1000 gms./m.sup.2 .multidot.day; and (b) a continuous hydrophilic sheet attached to or penetrating the first sheet, the hydrophilic sheet having a moisture vapor transmission rate exceeding 1000 gms./m.sup.2 .multidot.day and forming a barrier to passage of fluids. The composite is useful in diverse applications such as a padding under orthopedic casts and as thermal insulation in wearing apparel.
