I only know about the Sargent seat covers mixed with synthetic pants. I wear an Aerostitch Roadcrafter suit every minute I'm on the bike. After a few 10's of k's of miles the stock Sargent cover isn't so slippery. I never really noticed it being "sticky" or "abrasive," you just don't get the unexpected slide from time to time. To be fair, I had it on a seat made in 1999 for my VFR. It went from a '98 to a '99 to a '99 VFR (loved that model!) and when I sold the last VFR in 2013 the seat, while not looking new had no wear spots or cracks or tears in it after >250k miles of seat time. If it fit the Ninja I'd still have it.
When you call Sargent, talk to them. The few times I have called a) a human picked up the phone after a couple rings and b) the person who picked up the phone was a biker who knew knew their stuff. The '99 call was when they suggested that since I wore textiles I might be interested in a cover that wasn't so slippery. In 2013 I forgot to ask and they didn't mention the dtx cover material and got the slippery stuff.
