I really wanted to like these pants but there were to many little things that I didn't like to keep them. The main thing I didn't like were the zippers. All the zippers, hand pockets and the ones for the vents, are the style with large hard teeth (see picture) and are very course against the skin when you slid your hand beside. I understand why they chose this style because they will not bind and they are waterproof but I could just see myself drawing blood on the mountain trying to get to my ID. Also, the vent zippers extended all the way down alongside the knee and when I played around in my stance, they bunched up and jetted out which was kinda funky.
I say that they run small, but only slightly around the waist compared to other Marmot pants I have worn. Marmot pants usually fit well and account for my large hips and narrower waist. Maybe because they are insulated, but bending over to strap my bindings would not have been comfortable.
I hope this helps.
