These are some serious duty pants. Really thick fabric but yet stretchy and comfortable. I love them. It has great pockets, four in all and two huge vents. The cuffs on the bottom fit around a ski boot and also have a sinch incase you want to put them around smaller boots. The waistband is very comfortable and has an internal adjustment to get the fit just right. I have worn these pants through many days of skiing front and backcountry, ice climbing, and up to 19,400 feet climbing in Ecuador. I can wear these pants with a single baselayer down to -20 F and still be comfortable. If this pair ever wears out I will buy the Rubicon pants again.
