Had my first outing in my Battlefront Shock Trooper this weekend. Despite having a fan fitted in the helmet, the fact that the frown is filled-in means there is less than normal airflow, causing really stifling conditions.
So I was thinking of fitting a small flexible tube, venting to the underside of the helmet, with a mesh cap so I don't inhale flies (!), which I can use to breathe through. It won't be visible outside, but I'm thinking that at least it would keep moist air out of the helmet and allow me to breathe fresh air.
Anyone tried this?
