Is he really the first person to question this?

Good to know. Note to self: ditch the chin curtain if I ever get a helmet with one. Wear earplugs to keep it quite if needed.

It only traps the co2 when stopped. That would often be in traffic? Traffic fumes probably far worse than a bit of stale air. Curtain might even keep fumes out when in stationary traffic.
Also, I usually raise visor when stopped anyway.
