Does or has anyone here use a chin strap to help secure the helmet? Reason I ask is that last year I installed rectangular foam inside on the sides of my helmet. My helmet stays on much better but it gets rather hot. Without those pieces... inside the helmet doesn't get hot at all plus my visor doesn't fog either. I do use padding/foam inside the top of the helmet which is comfortable and I do need it to line up my eyes to the visor. So....I need to find a solution to secure my helmet down when I remove the foam side pieces from the helmet. I thought of installing a chin strap but wanted to ask around here first before taking that step. Any tips and suggestions are welcomed. Thanks!
