The covering layer consists of a drapable, water vapour permeable, low-emulsifier, pressed polymeric foam film based on polyacryl acid ester, polyvinylacetate acrylate, and/or nitrile butadiene with a surface weight of 15 to 50 g/m2, which, relative to the foam weight, contains 1-15% water repellant agent, 3-15% of an ammonium or alkyl ammonium salt of a long-chain fatty acid with a carbon number between 14 and 20 as a foam stabilizer, and at least 0.25% methyl or methylhydroxyalkyl cellulose as a thickening agent. The sheet or garment cloth has good drapability whilst exibiting the required properties of good wear-resistance and water impermeability.
