While Pa is not known as a high temperature area, we do get warm & humid at times. Yesterday, for example - upper 90's in temp with close to 90% humidity.
I have the Schutt's protector but do not use the ice packs. With the way i sweat, those packs would be gone by the end of the first inning. Genereally, I just make sure that I've got plenty of water - room temperature water - in me. I'll drink 2-3 20 ounce bottles during a plate game.
In between games in tournaments, I'll make sure that I get the uniform off and some shorts on - trying to stay out of the sun.
Use suntan lotion, follow the philosophy that if you don't have to go, you need to drink more and you'll do fine in the heat.
And all that heat just makes the beer taste better at the end of the day.
