A flexible, microporous, non-water soluble, non-skin-toxic film is provided for use in protective garments such as diver's suits, foul weather suits and the like. The film is of a thickness in the range of about 12.5 mu to 12.5 mm and possesses about 100 to 1000 pores of a diameter in the range of about 2 to 100 mu per cm2 of film surface. The porosity of the film permits the passage of body vapors but prevents, at least up to modest external pressures, the counter-passage of water. The film can be of a foamed material to provide increased insulational value.
