Helmets off gas from the foam and it loses its ability to absorb impacts.

Also, if you are ever in an accident where your helmet takes a hit, get a new one. They are more like airbags than people realize, once it absorbed an impact, it’s done.

Saw a couple people on lectric ebikes today, each with a small kid on the back. None of them were wearing helmets. Guess that’s the life hack… never need to replace your helmet if you don’t wear one.

I replaced mine earlier this year, got a POC Tectal MIPS. Really like it.

So like if you stopped it?
