Helmet warning

[Mixagon_imp]

Makes me wonder. Surely, if all that’s disintegrating is the lining, it could be replaced? Or is there disintegration in the harder structural material?

That was my first thought but I doubt there would be much saving against a new helmet if it was even possible to obtain a new lining.

Also what came to mind was how some plastic goes very brittle with age, not the same material as helmets but buckets seem to split and crack quite quickly even if not used.
