In reply to pisspotcharlie:
I love mine. Not done any trad in them yet but I have bouldered in them and they were decent enough for that. I find full softshell trousers more stretchy and thus better for climbing things, though.
That said for hillwalking they are awesome and they're definitely rugged! Knee vents are really good and lots of pockets. Softshell patches are a nice touch.
I mainly bought mine for geological fieldwork (where they take a fair battering!) but I use them on the hills a lot as well.
