Kevlar helmet shelf life

[TallGuy]

I recently bought a Dutch kevlar helmet in brand new condtion and it's dated 02/97. How long will it offer protection?

[Uncle Sam]

A long time. Don't even worry about it.

[Digital Marine]

Will a helmet ever NOT give protection???????

[radon]

Long long time still to go

[Jack Mehoff]

As long as you don't use your kevlar like a hammer to pound in those stakes

DuPont conducted some research into soft body armor (kevlar armor so the findings probably wouldn't be any different with a helmet) and the "shelf life" was considered "practically unlimited, ballistic decay without use is unlikely" so assuming it hasn't been mistreated during storage you don't have to worry about a thing.

5 years to be safe.

-7 years ;D
