"Literally the perfect warm pant. So awesome for hanging around the campsite and for cold mornings. Havent gotten a chance to wear them belaying yet but I can only umagine they’ll be just fine!"
"Layering is a must do during a backcountry skiing expedition and last week we encoutered some of the worst cold I’ve ever seen in Canada and I was able to stay warm whenever I stopped and feeling light when I was hiking! The only thing I would add is an opening between the leg to vent when hiking. Just like the ones on both side."
"Love the full side zip. Made it easy to transition"
"Wonderful fabric and thoughtfully designed. You can control temp with the side zips. Size small is a bit long for 5'3" . Slide on and off easily over shoes. Great for cold nights in camp"
"Great pants. Very warm and the big zipper in front lets you get your belay loop out so that you can stay warm when your friend in hang dogging/working some sections on their project."
"Bought these to use on Aconcagua, and though I did not end up needing them a whole lot as we had good weather, I was very happy with the quality and the convenience of the full zippers. Kept me nice and warm in the evenings at the higher camps."
"I wish the sizing was a little more inclusive. These are about 4 inches too long for me. I got the size medium to fit over muscles and layers. 5'3" female, 130lbs."
"These pants bring the heat. Easy to get on with the full length zips and durable enough to survive a couple accidental crampon pokes these pants are great to have in anyone’s pack. If the day take longer than you thought it would, or the overnight low Is lower then you’d like it to be these pants are your legs lifeline. If I’m doing something serious in the winter these are in my pack."
"Well made and very warm. Great chance to warm up while giving your partner a catch."
"Really good insulated pants for really cold conditions. I found a little bit big the size."
