Would you mind doing a quick run down of the Mountain vs the Fjell pants? By chance I've been looking at both of these but can't decide between them.Haglofs rugged fjell trousers. I prefer them to the Klattermusen horg trousers I have and rate. I have Rugged Mountain too, all of these are several years old and I live in them when not at work.
Still I think the balance of durability, breathability and quick dry, my Rugged Fjell win. At four years old, stalking, in the brambles, in the Cairngorms... They still appear to have little wear.
