My favourite feature; whether by design or not, is the general feeling of comfort this mat gives your whole computing experience. If like me you like to rest your arms or elbows on the desk while you chat or play then you will love the Ripper XXL, your whole desk becomes a comfortable, cushioned environment. I have to be honest, even if I didn't want to use a cloth mouse surface, I'd be very tempted to buy one of these just to sit underneath whatever other pad I choose and the rest of my desk of course.
