On my Arai, if the shield is up, the top vents are still exposed. Though I'd
suspect the raised shield to deflect flow above the vents. Not easy venting
a helmet as it usually results in more noise.

I have no idea if this would weaken the helmet. But to get airflow, you
would need forward facing scoops.

Riding in June in Vegas?  =:O

But it's dry heat.  :)
BTW, that is the ideal place to have a cooling vest.  Very hot and very dry.

In hot weather, airflow is everything.
