<p>A life-jacket comprises an inflatable bladder 12 having left and right lobes 15 and 16 and a back portion 20 which is connected to the left and right lobes by left and right shoulder portions 25 and 26 respectively. The inflatable bladder includes a neck aperture 18 between the left and right shoulder portions. The shape of the neck aperture is asymmetric with respect to a left-right centre-line of the bladder. There may be a channel between the left and right lobes which opens out to form the neck aperture when the left and right lobes transition into the left and right shoulder portions. The asymmetric shape may be caused, at least in part, by the neck aperture opening out more sharply on a first side of the life-jacket than on a second side. A length dimension of said neck aperture, as determined in a direction parallel to said centre line of the bladder, may be greater on said first side than on said second side. A retainer (31, Fig 1) may be provided around one shoulder portion of the life-jacket.</p> |
