There's also a helmet called the Torch with built-in lights.
Perhaps 'compliant'?
'MIPS compliant' would be a new term for me. MIPS is a mechanical design which it is said reduces helmet rotational force at impact. It is one of several such designs. It would seem a particular helmet either uses the patented MIPS design under license or does not. Educate me.
The one review I read on it says it's a MIPS helmet not MIPS compliant whatever that means
