I've been really happy with the De Soto arm coolers. I did my HIM at the end of July in them and a De Soto sun cooler bike jersey and it worked really well for me. I didn't overheat on the bike or the run.

Bike jersey is a pain in the neck to get on when you're wet. But it's not like those extra minutes in transition cost me a podium. And the lack of burn on my lower back and shoulders was worth it!
