Jerry, Icon direct sells through Amazon. I replaced my fenders this summer. I used the Icon site to figure out what part number I needed, searched it on Amazon, and found it. It was priced a few $ less than direct from Icon, and shipped for free. Win-win, as I prefer to purchase things through Amazon.
I was happy with the product. I'm not sure it was thicker or better than the original. But it was at least equal, and I do know that my installation technique was a lot better than the factory.
