Michael Brookswrote a review of The North Face Freedom Pant - Men's on October 25, 2008
I got these a year ago, which I took them snowboarding, snowmobiling, and ice climbing. Which they kept me more warm. I never needed to wear any layers under them, even when ice climbing in a dark canyon where the temps were below 0. Also the lining is pretty good, it is very minimal, so it keeps the pants light and some what flexible. I would probably not wear these for any mountaineering, because I could not imagine walking miles in these, they are not flexible enough. I would probably find something a light less tight and a bit more flexible in the knees.
