I have two pairs of these, one that I have taken out on climbs, hikes and snow climbs multiple times. They are great pants, with a little room for improvement in some areas.
Fit:I love that these pants have some stretch and seem to fit me even if I gain or lose some weight. They are slim through the hips, but would probably stretch out a little if needed. They also have a drawstring cord for adjustability. I would recommend getting the smallest size that fits because they do stretch.
Material: The DWR treatment is great on these. I hike in the snow with them and rarely get wet. It's not waterproof, but if you aren't sitting in snow, they work. They are however really warm in the summer. I have another pair without the DWR that's much better on warm days.
Technical Features: Its always nice to have convertible pants. That said, I would rather the version of these with the DWR not be convertible. They are way too hot for any situation where I would want to wear shorts and the zippers are cold around my legs in the snow.
Durability: Average. They seem to have lasted for me, but do look worn after a while.
Areas for Improvement: Waist band. Every time I wear this with a heavy pack, the draw string in the waist band rubs into my skin and leaves a rash. Part of the problem is that after a while, the material is so stretchy that the drawstring has to be tightened to keep the pants up. Then the drawstring rubs under the hip belt of a pack. Not a problem if you are using them for other purposes or for shorter duration and washing and drying them before they stretch.
