When to Replace Life Jackets
Everything you need to know about the lifespan, warning signs, and replacement timeline for life jackets.
The Short Answer
Life jackets (PFDs) do not have a fixed expiration date, but the U.S. Coast Guard recommends inspecting them before every use and replacing them when buoyancy, fabric, or hardware shows signs of degradation. Most life jackets remain effective for 10 or more years with proper care. Inflatable life jackets require more frequent maintenance, including CO2 cartridge and auto-inflator replacement.
Why Life Jackets Need Replacing
Inherently buoyant life jackets (the foam type) lose buoyancy as their closed-cell foam compresses and deteriorates from UV exposure, moisture absorption, and physical wear. The nylon or polyester fabric shell degrades from sunlight, mildew, and abrasion. Buckles, zippers, and straps can weaken from salt water exposure, sun, and mechanical stress.
Inflatable life jackets have additional maintenance concerns. The CO2 cartridge can lose charge, the auto-inflator mechanism can corrode, and the inflation bladder can develop leaks. The U.S. Coast Guard requires annual servicing of inflatable PFDs used on commercial vessels, and similar maintenance is advisable for recreational use.
Storage conditions significantly affect lifespan. Life jackets stored wet, in direct sunlight, or in hot spaces (like a boat compartment in summer) degrade much faster than those stored dry and out of the sun.
Warning Signs It's Time to Replace
- The foam feels thin, compressed, or crumbly when squeezed
- Fabric is faded, torn, frayed, or has visible mildew
- Buckles, zippers, or snaps are broken, corroded, or difficult to operate
- Straps are frayed or the stitching is coming apart
- The life jacket does not keep you floating with your chin above water (buoyancy test)
- For inflatables: the CO2 cartridge is punctured, corroded, or past its service date
- For inflatables: the auto-inflator bobbin shows signs of water exposure (green tab has dissolved)
How to Check the Age of Your Life Jackets
Most life jackets have a manufacturer label inside with the manufacture date and U.S. Coast Guard approval number. To test buoyancy, put on the life jacket in shallow water and relax. If you must actively work to keep your chin above water, the jacket has lost too much buoyancy. For inflatable models, check the CO2 cartridge for corrosion and verify the weight printed on the cartridge matches the model requirements.
Replacement Recommendations
Choose a PFD that is U.S. Coast Guard approved and appropriate for your activity. Type III PFDs are the most common recreational choice for boating, kayaking, and paddleboarding. Children must wear youth-sized PFDs; adult PFDs do not provide safe flotation for children. For frequent boaters, inflatable PFDs offer comfort and are more likely to be worn, but require maintenance. Always try on a PFD before purchasing to ensure proper fit. A life jacket that is not worn provides no protection.
The Bottom Line
Life jackets do not have a fixed expiration date, but they do degrade over time. Inspect before every use: check foam firmness, fabric condition, and hardware function. Perform an in-water buoyancy test annually. Replace when buoyancy is reduced, fabric is deteriorating, or hardware is failing. The best life jacket is one you will actually wear.
Frequently Asked Questions
Put on the life jacket in shallow water where you can stand. Relax your body and tilt your head back. The jacket should keep your chin above water without effort on your part. If you have to tread water or actively hold your head up, the life jacket has lost too much buoyancy and should be replaced.
Children outgrow life jackets frequently, which effectively creates a shorter replacement cycle. Always check that the child's weight falls within the weight range printed on the life jacket. A life jacket that is too large can slip over a child's head in the water. Beyond fit, inspect children's PFDs with the same criteria as adult PFDs: foam firmness, fabric condition, and hardware function.
