Helmet warning

[GoldOxide_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?

I reckon most are referring to the open cell foam padding. The superstructure ought to be intact (assuming no impact events). One might be able to source some new padding, but the helmet interior will become "customized" and could be an unintended liability. Might be easier to simply replace the entire unit.
