They are black diamond only. Nobody makes them in the "premium" fabric, and nobody makes sliders. I've been on the phone with several people from Rampage and a few other companies, and there's no belief in a market large enough to warrant the development cost in slider uppers. There are also no "skins" available, only complete uppers. I love my half doors, I'd love them more with slider uppers. Several people on other forums have decided they are going to make their own sliders, or slider kits, but nobody manages to follow through.
