I got these last year and I have used them for 4 days of snowboarding. I spend a lot of time just sitting in the snow and these kept me warm and dry. I wouldn't say that these are insulated but the thickness of the outer material provides some warmth. I wore only a thin synthetic baselayer pant underneath and I was warm and dry all day in about 30-35 degrees. The fabric that makes up these pants is (like other reviewers have commented) soft to the touch and pliable but also thick and tough. I wasn't worried about snagging when the trees got thick.
The waist features 3 loops (2 side, 1 back) for powder skirt integration. A loop for your lift ticket. Velcro/elastic waist adjustment. The hand pockets are lined with a very soft, warm material. The cargo pockets are not bulky but they will hold what you need. There is a snap on the back of the calves to keep the bottom of the pant from dragging in the muck in the parking lot. The gaiters fit my board boots well and have a hook that grabs onto by boot laces to keep the gaiter from riding up.
I am 5'11", 185 lb and I have a 32" waist. I got the medium and the fit is good for snowboarding. I have to cinch the velcro straps and tight as they will go to get this to fit my waist but I typically keep them a little looser to allow my fleece layer to be tucked in. I typically wear a 32" inseam and the length on these is just fine.
I like these pants because of the fit and the tough, waterproof material. Also, I got the Heron blue which is basically royal and they look great. They are not shiny like most pant materials.
