Love these I'm in remote Alaska towards the end of the Yukon and I don't go anywhere without them I can do 100 miles on the snow machine at -20 without the wind chill or 14 hours at work 7 days a week and never need anything else.  Not sure why anyone else would?

It's been over a year and these still look like they have a few more on them I used a knife a lot and have sliced and patch them but no ware holes at all.  A little oil or wax on the zipper/buttons I should have another few years of use.  Still very happy:)  Also when they do get wet they don't hold the water and add a bunch of weight like many others do.
