NelsonLocal wrote a review of The North Face Pamir Windstopper Jacket - Men's on March 24, 2013
Having had a chance to try this jacket in cold weather now, I would give it a solid rating. Even though I have had some affiliation with Gore for quite awhile, this was one of the first Windstopper garments i've had a chance to really try out. These are great for just about any cold and/or windy (and/or snowy) condition short of outright steady rain. For that you'd want to put on a Gore-Tex shell of some sort (accept no imitations). The Windstopper stops wind - as it name implies - whether the "wind" be from the weather, or do to your own bombing down a steep ski run. Zip up the jacket to the chin and you are good to go on the slopes. One of the previous reviewers compares this jacket unfavorably to the NF Denali jacket, but I wonder if he is comparing this one to a non-Windstopper Denali jacket; which would explain the breathability difference. I would say the Pamir jacket is as breathable as you would expect, and it works fine under a shell, if the situation calls for it.
