Overtrousers for warmth.

Looking for a suggestion for a good pair of overtrousers that have knee protection and fairly warm too.
I have a pair of plastic overtrousers that are good for the rain but have no knee protection and aren’t great with the current chill in the air.

I just need something to throw over my jeans/trousers for commuting rather than a regular tighter fit textile trouser.
The Rukka Granite was what I was looking at before but they seem to have been discontinued.

Thanks folks.

I wear textiles over my civvy trousers with full armour
Saved me this week big time

I love my Tucano Urbano Panta Urbis textile trousers - waterproof, full length side zips so easy on/off, removable thermal/quilted lining, knee armour. Very toasty, even in this very cold weather.
