Hi Mick,
Just curious, what did you pay for your vest? Back in '01 my Marsee vest was $125.
Just ran across your post John.
I purchased the vest from Silver Eagle Outfitters. Their website shows it to be $95:

Hopefully the cheaper price I paid doesn't mean reduced quality from the one you bought several years ago.
BTW, saying a cooling vest doesn't work or is worthless in high humidity is just wrong. If you're moving it's working. Sure, you feel warm and clammy but your core temp is being better maintained
On a purely technical level sure, you're gong to get
some evaporation but the reality is that in the 75% to 95% humidity we often experience down here in the hot summers, that small amount of cooling will be offset by the discomfort of having a warm, clamy sheath wrapped around you (which you mention) that is slow to dry. This reduces the practicality of it's application. This is not just conjecture but is based on posts I've read over the years from folks who actually live along the coast and have tried the cooling vests. Trust me, if a cooling vest was a practical solution down here, every biker would be wearing one during the summer.
I've ridden along the Gulf Coast area for enough years to know that as long I'm moving, I'm OK, even in very high temps because of the fairly low evaporation rate. Sure, it's warm but not intolerable. That's why I've never bothered to try a cooling vest. What is dangerous near the coast is being stopped or stuck in crawling traffic on a 95+ degree, very humid day with heat pouring off the concrete and the ST's engine. I actually came close to getting in trouble in such a situation about 10 years ago. Started getting light headed and nauseous. I had to find shade and a water source immediately or I was going to go down.
My purchase of a cooling vest now is dictated by an upcoming trip across parts of the desert southwest in August where temps can be in the 110+- range with very low humidity. In areas like that, the practicality of a cooling vest is undeniable. It's gonna be a hot trip! :biker:
