It is an important question to ask when going out on the water: “Do life jackets lose their buoyancy over time?” The good news is that in most cases, the answer to this question is “No”. Life jackets are designed to last for many years and retain their buoyancy.

Reasons Life Jackets Maintain Their Buoyancy

    • Heat and UV Protection – Life jackets are manufactured with materials that are heat and UV resistant. This helps to protect them from the harsh conditions of the outdoors and keeps their buoyancy properties intact.
    • High Quality Materials – Life jackets are typically made from high quality, durable materials like nylon, Coated Fabric, and neoprene. These materials have superior buoyancy and can withstand the elements, so they will hold up for many years.
    • Careful Maintenance – Keeping life jackets clean and properly stored can help to extend their life and protect their buoyancy. It is important to follow the manufacturer’s instructions for proper maintenance.

When it Comes to Buoyancy, All Life Jackets Are Not Created Equally

It is important to remember that not all life jackets are created equal. Some life jackets are more buoyant than others, and some are designed for specific water activities. Different materials, sizes, and designs can all affect the buoyancy of a life jacket. It is important to select the right life jacket for the type of activity and conditions in which it will be used.

Periodically Test Your Life Jacket

With proper care and maintenance, your life jacket should last for many years and retain its buoyancy. It is still a good idea, however, to periodically test the buoyancy of your life jacket. Testing also helps to make sure that any straps and buckles are secure and in good condition.


Life jackets are designed to last, and with proper care, they should maintain their buoyancy for many years. Tests should be conducted periodically, however, to make sure they are in good working condition. Be sure to select the right life jacket for your activities and always follow the manufacturer’s instructions for proper care and maintenance.
