Are there rules associated with the age of a batting helmet and at some point it needs to be taken out of service for either USSsA or national coaches fastpitch Association. I know in construction and hardhat times out after 5 years.
Men can wear their helmets a lot longer than we can. The products that young ladies put on their hair, is thought to break down the inside of the helmet. It is worth looking into.
There are no dates on the helmets, as long as it has the NOCSAE seal and corresponding tag on the facemask and is not damaged in any way they are fine to use.
