fantastic, if you can afford them!
These bibs are fantastic for anything mountain. I use them above my soft-shell pants for mountaineering, ski-mountaineering, telemark skiing & ice climbing when weather & conditions dictate. The double zipper on the side zips are perfect as you can open them up to get great ventilation and breathability when chugging up-hill, and quickly close them if heading down-hill in powder when you don't want a snow drift as one of your layer's. I did replace the cords on the zipper with some longer accessory cord I had so that I could more easily pull them with heavy gloves on. Also love the keprotec on the inside of the ankle's. Could use that on the seat as well. Mine have an inner snow collar, so not sure when the version changed for the fellow who commented on that below. The only reason I don't give these 5 stars is the price tag.
