I do not deal well with the heat, so I need a massively vented helmet. I also would like a visor on the helmet, to help keep the sun off my face. Even with SPF 70 sunscreen, I'm still seeing sun damage on my cheeks after I ride.

I have an old Giro Pneumo helmet with a removeable visor that I'm currently trying to replace. But no one seems to make super-vented road helmets with visors anymore.

I found one at the LBS -- a Louis Garneau Quartz -- but the plastic that holds the dial for adjusting the fit came apart when I went to put the helmet on. I can snap it back together, but I'm worried that it will come apart often, since I saw another helmet at the LBS that was completely missing the adjusting piece, like it had fallen off and gotten lost.

I'll wear a mountain bike helmet if it has enough vents.

Any ideas???? Thanks!!!!
