just had my brother hand me his koolbak back support belt. I was complaining that the back support belt I was using got to hot and I was sweating and giving me a heat rash. The koolbak I'm wearing I can actually feel the cool air on my back, and not sweaty. Koolbak is located here in Oregon and all of his belts are made in the USA. Im taking the wife and myself over to his shop for a custom fit belt .
Here is his web site, he said he would do a group buy or possible discount, say your from the forum
