I got a set of these last year for our annual balloon fest. It was so hot you almost couldn't stand to be outside. They really saved my weekend. This year I am going to Disney World in JULY!!!! I'm getting a new one just for that trip. The old ones are still in good shape, but everyone wants to borrow them so I will now have enough to share. I wouldn't be without them. I keep them in my car in a backpack so I am ready for any hot weather. Great!
