I haven't used this specific brand of cooling vest, but I have used a cooling vest for work purposes and they are worth their weight in gold imho. I am a bomb disposal technician and during a chemical remediation job I did in Oklahoma last August it really saved our bacon!
We were if full chemical protective suits, which trust me, do not breathe a lick, in temperatures in the high 90's with about 85% humidity. If it wasnt for the cooling vests that were supplied, the job would have been physically impossible.
I also live in Texas (Houston), and the cooling vest is defineatly on my list of "must haves" for riding gear. Now they wont help keep you cool all day long, your looking at probably about 2-3 hours of usefullness per cooling insert. For your commute I'd suggest keeping a set of inserts at work and at home and swapping out on each leg of your commute.
Anyway, hope this helps you a bit....
