The concept of buoyancy aids dates back to ancient times. Early civilizations used inflated animal skins or cork blocks to stay afloat. By the 18th century, sailors began using cork-filled vests, marking the first recognizable life jackets.
In 1854, Captain Ward of the UK Royal National Lifeboat Institution developed a cork life jacket, significantly improving maritime safety. The early 20th century saw the introduction of kapok-filled life jackets, which were lighter and more effective than cork.
Today’s life jackets are made from advanced materials like foam, nylon, and neoprene, ensuring durability and comfort. Key developments include:
Automatic Inflation Technology – Modern life jackets inflate upon water contact, providing instant buoyancy.
Lightweight Design – Foam-based life jackets offer excellent buoyancy without bulk.
Adjustable Straps – Ensures a secure fit for different body types.
