I've been seeing ads for these pants, the look very similar to old school army wool pants or similar. I know they are not high tech latest and greatest, but in late season snow and cold, its pretty hard to beat a good old fashioned wool pant. Just wondering if anyone has these and what is your opinion of them? Mainly, how "dense" is the fabric? and how well are they made? I had some of that Gallatin wool by Columbia, and thought it was actually pretty useless because the weave of the wool was so loose or not dense, that wind and cold just seemed to cut right through it.
