Claim:
1. A flexible article comprising: a flexible fabric comprising a first side and a second side, opposite the first side; a polymer laminated to the first side of the flexible fabric, the polymer comprising a first surface and a second surface, wherein the first side of the flexible fabric is contiguous with the second surface of the polymer; and a plurality of nanoparticles partially embedded and partially exposed on the first surface, wherein the polymer has extruded between agglomerates formed by the nanoparticles to provide a plurality of polymer filaments ranging in length from about 1 microns to about 100 microns and in diameter from 20 nm to 500 nm, to provide a superhydrophobic surface, the nanoparticles having an average diameter of less than 100 nm.
