Wore these "No Sweat" hat liners for the first time in a 10:30 am game behind the plate in my plate hat. The game lasted about two hours, the sun was shining and I think the high temperature by the time the game ended at 12:20 pm got close to 80-degrees. I did not get one single drop of sweat down my forehead, on my face nor in my eyes. These are wonderful. Wished I thought of them. I will continue to use them for the rest of my career.
