I put on my wind rider back rest yesterday morning, and went on a 300 mile ride. At one point it was warm enough to be down to a T-shirt, and what I like was that I no longer get that sweaty spot on my back. I was wearing jeans, And never once was uncomfortable. Ever hear the saying, "Happy Wife, happy life?", well, the same holds true for your bottom, only quieter. 9 hours on the bike, on and off, and no discomfort from heat or moisture. The seat cover has not moved at all since installation.
