I got one of these http://www.soundrider.com/archive/products/techniche_evaporative_cooling_vest.htm and here is what I thought. I went out on a 95 degree day and drove around a storm for an hour. The humidity ranged from 40-60% I would guess. I loaded the vest and a cool tie for my neck with water and put them in a bag and went to get something to eat. I came out and put the hot wet gear on and my hot helmet much like I would do if I used it on a long trip and had stopped for lunch. I had a basic tee shirt under it and my mesh jacket over it. I was quite shocked at how well it worked. Even in the highest humidity it made the ride much more tolerable. I never felt to cool but can see if you got caught in a sudden cooling below 90 degrees you might even have to take the thing off. I felt better going and any speed and better sitting at lights. I hung it up after I got home and I feel the vest would have kept working for at least 4 hours in any weather. That is long enough for a tank full in any riding mode. It may last over 7 hours in best case. The neck cool tie is something I have used before and is also a great idea if you don't do it. The same cooling vest also has a version with it running up around the neck and might be a good to buy but I like having options so I got the basic vest and can have and combo I want. It does leave your tee shirt a bit wet when you take the vest off but I found that it just helped me feel better after the ride as it continued to cool me as I put things away and hung things up to dry. It is the first time ever that I have ridden on those temps, at slower speeds at the end and not needed a shower as soon as I got off. COOL! ---------------------------------- I will answer any question. It is up to you to figure out if I should have.
