Rated 5 out of 5 by from Amazing Backpack As a backpacker in the Pacific Northwest for 8 years now, this backpack is an amazing new instrument for my adventures. It’s a little small but that helps avoid bringing excess weight on my trips

Rated 1 out of 5 by from Not waterproof I’m on a 50 day hike in scotland right now and I have this pack. I bought it because it’s scotland. Obviously I’ll be hiking in rain. The first day of rain and I reach into my pack for my sleeping bag, only to find that it’s soaked! It’s september in Scotland and I’m shivering on a rainy night with 600 miles ahead of me. Luckily I had just finished the west highland way and I was camping outside fort William. Now I have to purchase a waterproof rain cover for a waterproof bag!? I’ll stick with osprey next time. Great pack otherwise lol I used it in the Northwest Territories and British Columbia with no issue. It sits well and I covered 100 miles in 6 days with no pain at all. Best pack I’ve owned so far, it just doesn’t perform as advertised.

Rated 5 out of 5 by from Excellent Mountaineering Pack This pack has worked great for mountaineering in the Cascades. I've taken it on many mountains and it's held up great. The crampon pouch is super helpful and I get my crampons on much faster than fishing around for a crampon bag. My one complaint is no water bottle holders, which would be nice for approaches.

Rated 3 out of 5 by from Cheesy hip belt The hipbelt on this pack is undersized and of poor construction. The surface material is a knit that is not bonded to the padding and, out of the box, is already loose. Same thing on the shoulder straps. Other than that, looks like a good pack. I think I prefer it to the women's version but even the unisex small is too big by a couple of inches. I wish that outdoor gear companies took their female clients seriously.

Rated 5 out of 5 by from Great climbing pack Being 6'4", it can be hard finding a pack that fits. The large size fits like a glove. Great for backcountry ice climbing and climbing in the Cascades.

Rated 1 out of 5 by from Cheap Materials and poor warranty-Only lasted 4 trips I purchases the South Col Backpack for taking on big mountain trips. Worked fine on the first 3, but one the 4ths the area around the opening started to delam and fall apart. Then I would not be able to close it all the way. Warranty would not cover it, called it "Wear and tear" Buy another brand with better warranty.

Rated 5 out of 5 by from Excellent ski mountaineering pack I did considerable research to replace a 20+ yr old worn out Wild Things Ice Sac for multi day hut to hut ski touring and 3-4 day summer mountaineering trips. Criteria had to include lightweight, durable, close fitting, trim so as not to interfer with arm movements such as ski pole strides, non-bulky waist belt, attachment points for mountaineering hardware and a large enough kangaroo type pocket for a shovel blade. This last point is tough to find in packs like this. This pack delivers in all categories. It is very well thought out, and exceptionally constructed. And to make it even better, it's very weather resistant. I highly recommend it. My only suggestion for improvement would be to include a haul point on the front of the pack, but that's minor.

Rated 5 out of 5 by from Great Pack, Lightweight Excellent Pack, super lightweight and able to carry heavy loads. Splitboard ,boots, sleeping bag, tent, pad, food, appropriate, clothes, water and camera equipment were no problem for this bag on a 16 mile roundtrip hike. I am 5'10/'11 165lbs and the small medium was the perfect size. Just about maxing it out

Rated 5 out of 5 by from Favorite Alpine pack This pack, along with the 50L Direttissima pack, is my favorite pack to use in alpine environments. They are very durable, mostly waterproof or water resistant, and have the just the number of features I'm looking for. What I like most about this pack, and what makes it unique, is the removable plastic frame. I take that out and use my deflated air mattress as a soft frame instead to save some space.
