Abstract The invention relates to a life-saving garment whose material comprises a buoyant heat insulator (1), preferably an air bladder sheet, as well as to a method of manufacturing said garment. Manufacturing of life-saving garments involves a plurality of working steps, thus increasing the price of a garment. An object of the invention is to provide a simple and effective life- saving garment whose manufacturing costs are low. The garment substantially comprises two essentially continuous, human-shaped material sheets, affixed to each other only by means of an edge joint (2) One side of the garment is provided with a watertight zipper (3) as well as with a face opening (4), adapted to prevent water from flowing in the opening. The garment pre- ferably consists of two suits placed one inside the other, the top suit being turned inside out, said joints (2) of the suits being confined in an air space (5) between the suits. The life- saving garment is manufactured by affixing to each other two superimposed webs of a heat insulating material, preferably air bladder sheets, preferably by hot welding by means of a die or the like with a continuous edge joint (2), the entire garment being made in a single step into a human shape, preferably by a single depression of said die. (Fig. 1.)
