This is the best all-around pack for technical climbing and alpinism that I have used in my life.
Both my partner and I used it on a big first ascent in the Himalayas. We hauled it on the ascent and it did not have any rips or damage. Pack was comfortable to carry while climbing but when loaded with 8 days of food and arctic camping kit for 7,000+ M peak, I would suggest getting some detachable, cushioned shoulder strap pads, IF you plan to do long approaches. Adding them fixed all comfort issues.
I also took it out on another long first ascent and couple difficult rock-climbing routes, where it was EXTENSIVELY hauled. Also did a 4-day backpacking trip with my wife, where I carried all of our food and group gear. VERY durable, super light, has all the features that are needed for alpine climbing.
I love that there is a clip in point on the bottom of the pack, so you can clip the second bag to the bottom and haul them together. Also love that internal pocket has a zipper on the bottom, so you can access different things you stash in there from both sides. I usually overload that pocket with different things I want to use throughout the day and find it to be a nice feature because I can have my snacks/electrolytes on top and sunscreen, headlamp, headphones and lip balm on the bottom.
