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! January 31, 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
Rated 5 out of 5 by Big gun harness The big gun harness is an amazing harness. I'm guiding in this harness all day every day and it the most comfortable harness I have used. March 19, 2014
Rated 5 out of 5 by Big Burly Man Harness This thing will keep you comfortable in all day epics, or simply in an afternoon of cragging. Double belay loops, seven gear loops, a haul loop, and enough padding to help you retain circulation makes this monster a must have for big wall and aid climbing. May 17, 2013
