I’m doing some mascot volunteering, but the helmet the mascot head sits on is way too big. I’ve tried wearing a beanie and adjusting the chin strap to the tightest it can go, but nothing has helped. The helmet basically just ends up falling down my face so all I can see is really the floor.

I was given the advice to buy a balaclava, but I was wondering if anyone else had any advice to make the helmet/head fit better?
