Summer cooling equipment for tennis

Hey people,

It's obvious that it is summer and maybe more apparent than others depending on where you live. I'm in Austin and playing in the heat & humidity is GROSS. I've played in cooler climates like Maryland, I am from Las Vegas- dry heat, have live in Central Florida- humidity.

All the places I've lived I never thought about getting any cooling equipment until now. My leagues unfortunately play right at noon. I bought a cooling towel, generic Froggie towels and a cooling necktie too to try and keep me cool on the court. It worked pretty well I suppose.

What kinds of gadgets, equipment do you guys use and buy?

I heard about this wrist band that pretty much has built in ice cubes, funny..yes, but effective:?? How about this cooling skull cap? Any takers running out and buying it?
