• Lifejacket pre 1980s Kapok filled lifejackets with cotton straps are decades old and have not been manufactured since the 1980s. However, an unknown number are still being used. Kapok is a cotton-like fluff that is no longer used in lifejacket manufacture, because it naturally loses buoyancy over time and, if it gets wet, it will absorb water. Furthermore, the cotton straps rot over time, even if the lifejacket is not used, and will tear or break off the lifejacket when weight comes on it.
