Exposure to the elements seems the most common reason I've found in my research of what causes personal flotation devices to wear out.
Personal Flotation Device
Children must wear personal flotation devices at age 12 and younger.
In the US, it's called a personal flotation device, or "PFD".

The Personal Flotation Device (PFD) is seriously recommended when the weather is rough.
Because, especially if you can not swim, the device will keep you afloat if you fall in the water and prevent you from drowning.
Any/all children need to wear flotation devices when on board a personal pleasure craft. Everyone should wear one just out of common sense.
A PFD takes some time to fit properly, especially in an emergency
A personal flotation device (PFD) should be replaced if it is damaged, has lost its buoyancy, or shows signs of wear and tear, such as frayed straps or cracks. Additionally, if the PFD is past its manufacturer’s expiration date, it is advisable to replace it, as materials can degrade over time. Regular inspections are important to ensure safety while using the device.

According to Wisconsin law, all children under the age of 13 must wear a U.S. Coast Guard (USCG) approved personal flotation device (PFD) while on a vessel that is underway. Additionally, any person operating a kayak or canoe must also wear a PFD. It’s important for all boaters to wear PFDs for safety, regardless of age or type of vessel.
In Maryland, children under the age of 13 are required to wear a U.S. Coast Guard-approved personal flotation device (PFD) while on any vessel that is underway, unless they are below decks or in an enclosed cabin. Additionally, all individuals participating in certain activities, such as water skiing or riding on personal watercraft, must also wear a PFD. It's essential for boaters to be aware of and comply with these regulations to ensure safety on the water.
