In reply to Hamish:
Got the G2 pants recently and I'm very impressed. I wear them with thin bottoms underneath and they have been plenty warm enough, tested on some very cold days too. No need for gaiters either. I forgot my gaiters on my first outing with them and thought I would rip them to bits. I haven't even snagged them yet as they are quite slim fitting around the ankle. All round very good troosers and no faffing about with salopettes/gaiters, etc and the bottom of the route.
As for how they wear, to soon too tell but so far so good..
The only drawback may be if you've got sparrow legs, they are quite loose fitting which are perfect for my tree trunks.
