Abstract
Abstract A flotation life jacket formed to comprise a plurality of vertically extending pockets formed in the jacket with each of the pockets having a filler material, the filler material comprising cylindrical members formed of foam, the cylindrical outer surface of which is skin coated, the skin coating sealing the cylindrical surface and rendering it impervious to water and reducing the likelihood of the filler becoming waterlogged, thereby enhancing the flotation capabilities of the jacket. The shape of the filler material in the pockets also makes the jacket more readily conform to the shape of the wearer and eliminates any sharp corners and increases comfort and manouverability.
