I have one from when I had a Wintec and a bad back - they are comfy, look OK and are non-slippy so I would recommend them. They do lose some of their suede look with use and go a bit shiney in places but if you don't mind this too much its worth keeping an eye out on ebay
Best thing ever for me, it was never off my saddle until I got the WOW. Certainly made me feel more secure in the saddle, you feel a bit perched at first but once it warms up it moulds to the saddle and yourself and is great!
yes they are fantastic. i've had a bad back for over 20 years especialy after riding. Its no exagerstion to say the seat saver has kept me riding, my back is fine now . Definately money well spent. They are just great.
