A survival garment (10, Fig 1) for use in water comprises a body portion 13 for surrounding a torso of a wearer (23, Fig 3) and arm 11 and leg portions 12 for receiving the arms legs of a wearer. The body portion includes a back portion for covering a back of a wearer. An inner layer of material 19a and 19b is provided between the back portion and the body of a wearer and the inner layer of material spaces the body from the back portion by a layer of air. The inner layer has sufficient resistance to deformation to maintain said air layer under hydrostatic pressure when the wearer is floating on the wearer's back in water. The inner layer of material may be formed by two layers of material (20a and 20b, Fig 5) spaced by drop threads (21, Fig 5). An immersion suit formed by the survival garment is also disclosed. |
