Kapok (Ceiba pentandra) is a natural fibre, it has been available for many years growing throughout the tropics where it is cultivated for its fibres. It is a moisture-resistant, quick drying, resilient, and buoyant fibre and weighs only one-eighth as much as cotton. Kapok has historically been used in life jackets and life boats, supporting as much as 30 times its own weight in water.
