I bought a pair of the Nike Crowley pants a few weeks ago. The quality is top notch. I was debating on the Crowley pants to the Burton Cyclic pants and chose the Crowley because they fit me a little better and cause it was cheaper. The Cyclic was a little wider through the legs and felt a little too big for me. The gore-tex is very nice, kept me warm and dry in the few days I put them through this year.
You just answered in the last what I was about to ask next; the warmth. So you don't need anything underneath them? Like another layer?
I usually have Under Armour 2.0 underneath all my snowboard clothes. And I'll start sweating after a few runs and have to open the vents a little. I run a little hotter than most though. I'm probably going to get lighter thermals since I don't want to open up the vents and get wet. To compare I find the Crowleys to be warmer and definitely dryer than some some cheap Burton pants I got on clearance at REI one year (non gore-tex).
