I've had quite a few punctures on my Land Rover MTB recently and it's starting the annoy me. I bought some kevlar tyres for my road bike a couple of years back and haven't had a puncture since. I want to get some for the Landy too, but I'm not realy sure what I should be looking for.

I'm quite happy with the Innovas that came on the bike to start with - the grip well and they don't clog in heavy mud.

So, i'd like some kevlar tyres that are suitable for fast road cycling and some muddy off road cycling (I know the two don't generally come together, but it's worth a shot!) in 26x2.1 size if possible. Can anyone suggest any decent ones? I'd rather not have to pay the earth if it helps...
