I orderd cool vests for Jeanne and myself. They came in yesterday so I decided to try them out. No, my shirt didn't stay dry like they advertised and There was a little slimy feel on the outside. But, they work! My shirt would be wet anyway. Either it is full of sweat or I douse myself with water every few miles any way. It did tone the Texas heat down and I am sorry I didn,t try them sooner.
