Anyone else make anything similar to Microsilk?

Microsilk wasn't anything I was that interested in before, but now that I'm shopping for hot tubs it's something I encountered in the research process, and it interests me a little.

Is Marquis the only one that does this kind of tech?  Or do other makers have something similar under a different name?

I'm not opposed to Marquis per se, but if there are other options I'd like to look at them.
