Abstract of the Disclosure 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 thick- ness in the range of about 12.5µ to 12.5 mm and possesses about 100 to 1000 pores of a diameter in the range of about 2 to 100µ per cm2 of film surface. The porosity of the film permits the passage of body vapours but prevents, at least up to modest external pressures, the counter-passage of water. The film can be of a foamed material to pro- vide increased insulational value. -1-
