Abstract: The invention provides a life-jacket which takes account of the articulation zones of a wearer's body, namely those parts of the upper torso that bend, twist and flex when engaged in maritime activities. This is done by providing a life-jacket having buoyancy material with articulation zones in it which are coincident with a wearer's articulation zone. One particularly suitable form of life-jacket may incorporate a sailing trousers. The life-jacket (1) has an upper body garment which has seven front pockets (10, 11, 12 and 13) on each side of a front opening (4), namely lower pockets (10 intermediate pockets (11), chest pockets (12) and a shoulder pocket (13) defining a waist articulation zone (20), an underneath ribs articulation zone (21), a mid-ribs to armpit articulation zone (22), a below collar bone to a top of the shoulder articulation zone (24). Each pocket contains suitable buoyancy material. Further pockets are placed on the back of the life-jacket (1).
