I don't know anything about it, but it was, indeed, a cooling vest.

No no? I want to buy one!

I have a CTC-100 but (a) they seem to have disappeared, and (b) its not a hugely efficient system - big power draw at 10A.

It works OK, but it's time for there to be something on the market.
The cooling vest I use cost about $40 USD. Soak in cold water for about 10 minutes remove and wear over T shirt and under jacket. Good for about 1-2 hours (AZ weather), then repeat water soak.

As always, YMMV.
Unfortunately evaporative cooling vests - I have one - work very well in low humidity but are more or less useless in the deep south, hence the interest in an active system.

I would hope the reliability of whatever system the rider is using is adequate for an event like the IBR.

We'll read about it in the daily reports if things aren't sufficient for that rider.

If money is no object you can look at CoolShirt systems (stock car & drag racers wear these). I use a Veskimo cooling vest which works on the same recirculating ice water principle as CoolShirt, but Veskimo stopped manufacturing last winter. I do see a couple Veskimo systems still lingering around the internet, but they will set you back about $1000. Other than price, the only other drawback is that you have to set aside some extra real estate on the bike for the cooler.
