Air Conditioned Jacket

It would be like trying to run the A/C in a convertible with the top down, or outdoors on a balcony.  Just a waste of energy.

FWIW, I thought the same until I bought a convertible.  Running the AC works great, with the windows up.  When its 120 ? out, you take anything you can get.

I also use one of these Cool Danna's. Awesome product and makes all the diff between feeling hot and feeling like you're goona die out there...
