I found this site.

Is this what you're referring to?

Yes that's it, nice to see they're available again. My old Nordic's windscreen did a great job of directing wind right into your face, fun for a bit but tiresome if you go any distance at all. These Wind-Aways worked nicely and were easy on/easy off.
