Non rustle/crackly waterproof trousers or overtrousers? Where?

I've just picked up some toggi extreme waterproof trousers off ebay and they seem pretty quiet. I bought them with backing the youngsters in mind!
 
I had a pair of waxed cotton chaps with suede strappings. No flapping, rustling and plenty of grip which nylon overtrousers definitely don't give you!
 
Thank you all - I will look at all the suggestions, I like the look of the Mountain horse ones, but Toggi sound good too. I bet most will be too long for me, as I'm only 5'1" - so perhaps childrens length is more suited but I would struggle to get them round my legs!
 
Mandy - I had a browse on the Millets website and will possibly try and get into one of their shops to see. But they had quite a few in "short" sizes, so hoping that they might be short enough for me too? What height are you - inside leg measurement? Think mines about 28" which is pretty short!
Let me know if you find any please? Likewise I will too.
