I usually run some sort of under armor styled stuff. It allows me to get the sweat off my skin and prevent the suit from sticking to it. You also want to DRINK a ton of water, too. Get a fan to put your helmet on to cool it in between sessions.

It's tough and I have been in over 100 degree temps and ridng a bike for 1-1/2 hours at a time while endurance racing. We'd use camel backs... But, still sucked. Just fluids and fans...
