<p>The present invention relates to a rigid life jacket comprising a chest part and a neck part, the chest part comprising at least one buoyancy element with first sides and second sides as well as a first face and a second face. The first sides extend inward from both the first face and the second face towards a centre of the buoyancy element, so that the buoyancy element has more buoyancy near the first and second faces than at the centre between the first and second faces.</p> |
