It’s that time of year again.
I saw a car at the track with an insulated container that ice and water were mixed and a pump that quick connected to his vest. Wait it was amazing.
It would be great to have that same deal useful outside the car too. Maybe a unit in the golf cart? The ice pack vests are portable. But not sure how long they are effective. Plus you need to replace the packs with cold ones throughout the day.
Anything creative you guys are seeing or using?

This is what I see being used by some at our home track in Las Vegas, NV. I'll probably get one eventually. Till then, I use a cool T-shirt & when it gets really hot I add the cooling vest also. The vest is kind of a pain because it needs to be soaked in water before use. It last about 1hr. before being recharged.

I’ve seen the ultra chiller
But of course it does nothing while you mull around in the staging lanes with no shade. But the chiller looks perfect for the car. Wonder if the have a helmet liner
