Laminates of fabric and microporous polymeric substrates are taught which have enhanced oleophobic and hydrophobic properties. The enhanced properties are obtained by contacting the laminate or any of its components with an aqueous dispersion of polymer particles of an organic polymer having pendent fluorinated alkyl groups and in which the particles are very small, being on the order of 0.01-0.1 micrometer. The small size promotes uniformity of coating when the laminate or components are coated with the dispersion and then heated to flow the particles together.
