For those of you that have a coolsuit, how much do you fill the container? I think one of them has like 16 quarts and is supposed to last 4 hours so would you just put a 4 quarts in? Others are like 8-12 quarts...so still put around 4qts or do you need more like 6qts to keep it cool for a 45 min race?

So let's say you put 4 quarts in...that's around 8lbs right? (uhmmm 1qt - 2lb weight...cold water ...higher density...never mind) let's go with 8lbs.
I think the container's weight around 3-5lbs.

And the draw is around 2A at 12V yes?

And they run around $350-$600 (not including shirt...shirt is not really part of this equation)

One last ?
Which would you prefer:
$350-$600, 12V/2A, 11-30lb and having to change water/ice
Or
$200-$250, 12V/3-5A, 1.5 lb and fill & forget (no worries about ice)
Oh, and it will drive cold air for your helmet if outfitted as well.
Oh, and it will monitor and keep temperature at predefined setting as well - air and water can be seperate temps.

Thanks for your input.
