Best trousers I ever owned as they are so comfortable and so well designed. I wear them for everything from ski-touring to trekking to mountainbiking and even out at night as they need minimal maintenance and look good all the time. The air vents are so useful. There is a hook at bottom of the pants that can be used to lock pants onto shoelaces serving as gaitors. The pants have tougher material around knees and those parts where there is more wear and tear so I feel they will last forever. They are sturdy, practical, comfortable - perfect travel pants.
