I find the best pad that has worked for me and my horse, is made from a neoprene substance. I couldn't find the exact one online. But it is very breathable, and my horses don't sweat near as much as others I see when we go on trail rides, or even just to the arena. It also has good grip and doesn't allow the saddle to slide as much, and it is so easy to clean off, I just wash it off with a hose and let it dry. It also doesn't itch. One time, my horse hated a blanket so much, he lay down and started rolling! It was just so itchy.
