That's awesome to hear that the cooling vest is working out for you! It's good to get feedback on out-of-pocket purchases so people have a better idea of where it's wise to splurge and where it isn't.
The outdoor air conditioner is just hilarious! Sometimes I just so wish I could air condition the entire outdoor world to my liking! That would be great! Then I could actually go outside whenever I wanted!
The air conditioned mattress is actually kind of... "Cool"... I'm not sure how comfortable it the apparatus itself would be, but the idea seems neat.
I liked the link with lots of personal cooling gadgets. That was an awesome link! Thank you so much for sharing!
On a related note, I purchased a cooling vest recently, and I absolutely love it! I had been saving for one for quite a while, unsure of when I'd get one, but I finally just had to. It was a little expensive, (alright, a lot expensive), but quite honestly the best item I've ever purchased! I wear it nearly every single day!!! http://www.stacoolvest.com
