- Early forms of life jackets and floatation devices include inflatable animal skins (865-860 BC) and small pieces of wood (1700 AD) or cork (1757 AD).
- In the early 1850s, British captain John Ross Ward used cork to develop the first life jacket for the National Lifeboat Institution.
- In 1902, kapok, a fibrous plant material, was introduced as filler for jackets worn by navy seamen. It was banned in 1904 due to flammability and air cell compression, which reduced buoyancy.
- Balsa wood was approved for PFD use in the 1920s, but cork block remained the main material for life jackets until the Second World War despite many water-related deaths.
- Water safety developments improved during the Second World War when inflatable jackets and vests designed to keep bodies upright were introduced to the military and private citizens.
- The 1960s brought further improvements with the development of light and flexible synthetic foam fillers, which are still in use today.
