I purchased a custom seat back in 2012 from C & C Motorcycle seats, (by the way horrible customer service) after around 100 miles or so I started to feel discomfort on my butt. I took my seat to Danny Grey custom motorcycle seats and met with Lars, He suggested I try the AirHawk, I purchased it from him and I have to admit I was a little skeptical, but after my first ride with it, I couldn't believe the difference it made. I would highly recommend getting an AirHawk for you guys out there that might be experiencing the same problem I had. What a difference a long ride makes.
