Having switched from a Cool Shirt system to the FAST system, the shirts were interchangeable. Perhaps the fittings were the same before? I know FAST has a fittings kit that can convert hose fittings over from one to the other.

I have the hooded one and it's great. It's a little snug under my helmet and you look retarded putting it on. When not on your head, it works well at the back of your neck.
All the fittings should be the same. I am using an opti-cool cold therapy cooler and it mated up just fine.

Last summer I broke down and just made my own.
I bought a cooler from walmart, a marine bilge pump, some quick disconnets and some tubing. I made my own shirt as well, but had scrap the first shirt since it did not work out right. I was able to save the tubing.
Running the cool shirt in temps of 95F+ was great. I only ran it for the races. practice is in the morning and cool enough and qualfying is generally short enough to endure for a few mintues. Race time is long and often occurs at the warmest time of th day. So that is when I use it.
I found ths best time is actually sitting on grid. In the past getting suited up is tough when it is 102F out side. Then you put on all gear and wait race grid for 5 mintues at a minimum. Longer if there is a clean up before. Anyway the heat really gets to you when you are just sitting. However with cool shirt I can sit there for ever it seems and be quite comfortable. Very nice.
When racing you feel it less since your body is generating heat and you are focused on racing. So I really never "noticed" it since, but then again I never "got hot" either. In the end that is the key to never feel overheated in the car and that lets you focus on the racing.
For mine I use some old tupperware and make 3-4 ice blocks to fit in the cooler. I can't fit one big block, but I can get in some smaller ones. These will last all day (outside the car) and for the duration of the race.

For the rest of us, it is not too late to get in the group buy for the Cool Shirt System.......

Not meaning to impose on Paolo's group buy but reading Joe's comment made me want to share my experience.
Last year there was a thread on homemade coolers for cool shirts and I think it was BKS who turned me on to the Donjoy theraputic coolers. They can be found on fleabay all day long...
http://cgi.ebay.com/Donjoy-ICEMAN-Mo...3A1%7C294%3A50
The coolers come with all the plumbing and the fittings mate to the Cool shirt system...I converted it into a 12 V system and just plug it into the cigarette lighter...

Anyone know of a DIY variable speed switch that would regulate the flow?
I intend to get by with just a toggle but if there's a simple rotary switch I can get I may try a DIY version of what cool shirt sells.
Thanks.

Saw your post on Rennlist. We're doing a Lemons race this summer, and I've picked up a couple of the donjoy units off ebay. Just out of curiosity, how did you do the 12v conversion?
I don't know much about electricity. The Donjoy "IceMan" coolers use an AC addapter to change the current to @ 7 volt 1.6A DC. How did you set the unit up to run on the cars 12v system?
I've considered getting a DC to AC (?) inverter, and using the DonJoy oem brick to power the pump, or I guess there are some type of step down (are they still called transformers) to reduce the car 12-13 volt DC to the required 7 volts.
Any tips would be appreciated. Thanks
