A belt 72 may be provided which is held to the jacket by stitching 74 and a D-ring 96 between which it is held in place by loops of material as 80, 90, 91; a second belt 104 is similarly attached eccept that its position is adjustable by passing it either through loops 84 and 90 or through loops 86 and 92. The length of each belt is adjustable by means of a pair of D-rings as 96 and 98 which is fixed to the jacket by a short length of material as 94 and stitching, the other end of 94 carrying a snap hook 100 for engaging with a D-ring on the end 102 of the belt 72 thereby closing the jacket round the body, and similarly for belt 104. The back portion of the jacket may include two buoyant bodies 46 and 48 which like the front buoyant bodies may be made of foamed synthetic material, e.g. polyvinyl chloride separated by stitching 64.
