Polaris made a Touring Cool Air Pad for the rider and passenger seat for the Cross bikes but they never showed them as working on the Vision. I have them on my CCT. Their real purpose, which they do quite well, is to keep the seat cooler when the bike is in the sun. While you're on the bike, they don't flow any air under your butt. They look good on the bike, they don't raise you up on the seat and they keep boot marks off the seat if that's an issue for you. Plus they have the Victory logo embossed into them as well. I like them enough that if I found another set, I'd get them for my Hard-Ball as well.
The item numbers are:
2879363 for the Rider
2880738 for the Passenger
They have an elastic strap that goes under the seat to keep them on the bike. The Polaris Victory Touring Cool Air Pads are identical to the same items I've seen at H-D shops. Yes, Polaris has been 'borrowing/copying' things from H-D for several years.
