I just recently bought one of those HyperKewl Cooling Vests on ebay (for a STEAL too! Brand new, and well over half the price) Its this one:
I chose it over the full vest since I want more freedom and for it to be lighter and more breathable.
BUT, has anyone used them? Theyre supposed to last 5-10 hours to keep you cool. Which is well over how long Ill be wearing it. But with temps in the 102s here in Texas, and me having issues with the heat, I feel as though this should help me a LOT. Ill only be out for an hour or two riding. Can always dunk it in the horses water tanks in the fields if it dries up haha :P
Its supposed to come in this week or next, so Ill do my own review on here for others when I test it out, but Im curious if others have used one or something similar.
