In reply to janne: I've had a Rab VR Climb, Montane Scarab and Patagonia Ascentionist.
The VR Climb was suprisingly tough. The Scarb (what I replaced it with) seems to be holding up ok). Neither of these are particularly rainproof, but I don't expect them to be.
I mainly use my Patagonia Ascentionist for scottish winter. Seems to be holding up well so far - 1 small rip where I had something hard in a pocket and it got knicked on the rock. It's certainly not super-tough, but them, it's not super-heavyweight.
If you want bomproof toughness then you're going to be sacrificing comfort. I'd say go cheap and replace when trashed! There's not much that can withstand Lofoten Granite!
