Has any one either worn or know someone who has worn a helmet with a side air intake in a midget or lightning sprint? I know of one for sale that matches my budget but I'm not sure if it might not work well in a typical midget or lightning sprint seat.

I wore a Bell Turbo Air with double air intakes, one on the left side and one on the top for a few years in my midget without any problems.

How did you route the left side air hose? Over the top of the seat? Did it help prevent fogging?

Steve,
I use a Carbon Bandit with a Side Pipe. I use a 7.2 Volt Fan from Fresh Air Systems Technologies. Great people and yes it cures fogging and helps you stay cooler on those hot summer nights too!
