Rated 5 out of 5 by Burly design I'm happy! This is great for hanging out on big walls projects or even small walls on a fixed line. Maybe you're photographing your friend and hanging there for a while. Maybe a few hours fixed a route this is your harness! I'm happy it's comfortable it's like taking you're favorite lawn chair with you on the wall. July 8, 2015
Rated 5 out of 5 by Cushy I bought this for trad climbing, not aid, so can't really speak to that aspect of it. I was looking for something that would handle gear better than a sport-oriented harness. The padding is great and the harness is surprisingly light for its size. The only drawbacks I see are that the side gear loops are small--it's advertised as having a ton of gear loops, but the actual loop real estate isn't a whole lot more than a "normal harness". And the big gear loop in the back is awkward to access, especially with a pack on. That said, however, I'm very happy with the quality and features and am sure this will last me through many days of fun climbs. June 2, 2015
Rated 5 out of 5 by Excellent harness It's comfortable and well made. A huge improvement over my old one. The only nitpick is that I wish it was designed to tie in on either side as well as the leg loops thus eliminating the buckle as a point of failure. February 20, 2015
Rated 5 out of 5 by Superb big wall harness. I borrowed this harness to climb El Cap via Muir wall and the nose. Comfortable and great for organizing gear. Tie in points make it so you have room for multiple ropes. Haul loop is great as well. Made being on the wall for 6 days much more enjoyable. Highly recommend! February 1, 2015
Rated 5 out of 5 by Great for Rope Rescue Teams The super wide waist and leg loops make hanging in this harness for hours on end a lot more tolerable than any other alpine harness. This combined with the relatively light weight when compared to other rescue harnesses make it my #1 pick for any rope rescue team. December 16, 2014
Rated 5 out of 5 by Simple This harness is straightforward. Three double backing buckles, gear loops, and some added foam along with a thick waist belt for comfort. Not like some other new sporty harnesses with auto-backing buckles and helium inside the darn waist belt to help you scend. I have not figured out two things. I still need to work out adjusting those thicker than average leg loops, they seem to make it difficult to keep everybody down there in the same room, but I think with minor tweaking, I'll get it right. And the two smaller gear loops that are on top of another set haven't made sense to me yet, so I just don't use those. The large gear loop on the back is SUPER useful. As others mentioned, comfortable to wear, hang in, etc. November 5, 2014
Rated 5 out of 5 by Good Harness! It met all my expectations. I was expecting a large oversize harness, but it is just a little bit bigger than my old climbing harness, but will much more places to clip gear on and even came with an axe sling to boot. I am really satisfied with this new harness it was all that Black Diamond said it was! October 1, 2014
Rated 5 out of 5 by Very comfy This is the most comfortable harness i have ever owned. I didn't have any discomfort hanging and belaying for extended periods of time. I would recommend it to anyone planning on going on big wall climbs. thumps up June 23, 2014
