Query: softsides topper

I'm sorry to say that I did not like this item. Although it had enough space to put several pieces of luggage, it was totally NOT waterproof. It rained for 2 hours on our trip to GA from FL and when I got to the hotel, my clothes were all wet. It was also difficult to attach to the rack on my KIA Sorento. I had to stop many times to use duct tape to anchor flapping pieces of binding.
