The lifejacket is divided into three distinct portions; that is a headrest portion, a shoulder portion and a chest portion, the shoulder portion incorporating a neck aperture. A longitudinal slit is provided which extends through the chest portion from the neck aperture thereby dividing the chest portion into two similar parts. The longitudinal slit facilitates the fitting of the life jacket to a wearer. A one piece tape is provided which passes through two longitudinally spaced transverse bores, one extending through the headrest portion and the other through the chest portion.
