ABSTRACT:
A vapor permeable buoyant insulation composition suitable for floatation garments and the like is impermeable to water, and yet allows the escape of perspiration when the composition is used in garments or boots. The composition comprises a closed-cell insulating foam which has a plurality of holes distributed throughout, first and second layers of fabric, one layer on each side of the foam, and stitching pattern throughout the composition causing the first and second layers to be in contact at the holes in the foam.
