I used to scoff at the Air Hawk but last time I went down to the Island 800km in one hit my but ached for half a day so I realised My but is not what it used to be and considering the 60 day money back guarantee and the fact that I guy who has stand there selling them even offered to pay postage back to him, I took the plunge..... well lets just say he ISN'T getting it back NO WAY, they look like Butt Ugly but also it comes of in seconds I only use it for really long rides.
