In reply to Sliabh1982:
I have an arcteryx now and its brilliant, but for what youre asking, not worth the money - its really best for sport climbing or harder trad where you want something as light as possible as well as comfortable. Also Im not sure how long theyd hold up against occasional standing on the leg loops in crampons etc.
Previously I have had two Black Diamond Blizzards and they did a great job; would suit what you are asking fine, and also cheaper.
