Installed my Cool Cover yesterday and it fits really well and looks great on my 2017 BMW GSA with a Sargent Driver Seat. It actually closed the gap some between the tank and seat. I rode 225 miles today with the Cool Cover and it works as advertised. I could actually feel cool air under my butt. Just so you know it was an average of 85° today. I also like how the Cool Cover eliminated the hot spots I had on my seat. I have tried Air Hawk, Sheep Skin, and Butt Buffer in the past. If today’s ride is a sign of how the Cool Cover will feel during future rides I’m excited.
