This product works, it really cools your body ( buttock). I rode 26,000 km from eastern Canada to Alaska and back in a variety of temperatures. It really improved my riding and extended my time/distance between each stop. It also fits great on your seat. It’s so effective that when the temperature fell below 12 degrees Celsius, I had to lay something over it because I was getting cold. I also want to mention that the staff at Cool Covers were exceptional in dealing with. I recommend this product because it works. Please be aware that the Cool Cover does not solve all your riding comfort issues. The type of seat, the location of the pegs and other factors affect the overall comfort in a ride.
