The Black Diamond Big Gun Harness is a comfortable climbing harness for big wall action. The wide waistbelt and leg loops are all about spreading your weight over a larger surface area, making hanging in the harness for long periods of time that much more comfortable. Additionally, the bullhorn shaped waistbelt features thermoformed foam to add to the comfort. Thanks to easy-to-use trad buckles, getting in and out of the harness as well as adjusting is super simple and fast. When it comes to racking, you've got seven gear loops to choose from, which are also color coded for ease. Now that's what I'm talking about. Time for some vertical action.

FINAL SALE: For safety reasons, we cannot accept returns on load-bearing climbing equipment. Sorry for being so mean.

Product Reviews
Rated 5 out of 5 by from I like this harness So far I have only used this for about two months in the gym. So far so great. It fits well and is very comfortable. Some critiques I read about this is that it's hard to get the waist belt adjusted tight and difficult to double back the straps. Yes, despite the online description not saying anything about doubling back the straps, the instructions with the harness say to do so. Despite these two critiques I gambled and bought the harness and so far I am glad I did. Yes, tightening up the waist strap takes some getting used to but is not a big issue in my mind. Doubling back the straps is easy if you just pull back on the buckle a bit to 'open' it up. I am excited to take this outside to the crag!

Rated 5 out of 5 by from Very comfortable harness The Black Diamond Big Gun harness is an excellent choice for outdoor, or indoor climbing. Very comfortable as I am able to sit all day on it with no issues, and the 2 belay loops is a nice feature!
Date published: 2022-11-10
Rated 4 out of 5 by from Comfortable as described The harness is extremely comfortable and the gear loops are many! I love that there are 7 plastic coated gear loops. I prefer these loops because they don't flop around or sag under the gear weight and are easier to clip the gear onto as a follow. The downside is that they are small gear loops and lay stiffly and close to the harness. The other downside to this harness is that it's not doubleback buckles. This means putting it on and taking it off is a bit more cumbersome, feeding the strap through, tightening it, and doubling back the strap to lock it in at the waist. Overall, I am very pleased with the harness. it's great for a hanging belay and all-day multi-pitch climbs!

Rated 5 out of 5 by from Very versatile I bought this a few weeks ago and I have been it has been nothing but amazing. I haven’t completely finished testing it but I am very happy with the results so far. The belt has a very wide adjustment range to get over thicker pants for when it’s cold. Plenty of gear loops for as much gear as you could possibly need.

Rated 3 out of 5 by from almost great pros: love the hard gear loops, makes it simple to clip and organize gear. very comfortable on rappel, seems very well made. color scheme is unique. cons: the belay loop and hard points are very stiff making it sometimes awkward to climb in. the old school double back buckles for legs and waist are a nightmare. i can never get it tight enough to hold up a double rack. it’s constantly slipping down like a dirty diaper. the leg loops don’t stay in place if you’re trying to get a high foot then stand up. no modern buckle kills this thing.

Rated 4 out of 5 by from Great multi-pitch harness but can be between sizes This harness is action packed and super comfortable. I've taken it up over 100 pitches at this point. With the wear of the harness and putting a full rack on it it does get heavy and I noticed I couldn't tighten it enough. So I bought a second harness again in the smaller size in hopes that I would be able to not feel like it was falling off when a full rack is on it. The smaller size doesn't fit, and unfortunately moosejaw doesn't do returns so now I'm stuck with a smaller harness that barely fits my body and a medium harness that feels like it's falling off with a full rack on it. It's a bit of a bummer because I'd give it five stars and this company the same if it weren't for this situation. BD needs to update the sizes b/c I'm sure there are more people in the in-between S & M and M and L categories that are using a big wall harness. Also MJ needs to update their return policy b/c there is no way to try this harness on otherwise

Rated 4 out of 5 by from Comfortable, but not super comfortable. I bought this harness for photographing climbing on fixed ropes. I've spent up to 2 hours in this thing, and I'd say after about 20 minutes my legs start to feel it. I tend to get some relief by getting on the wall every 10 minutes to get the blood moving more freely to my legs. I'm using this is a very hot climate, so I'm in shorts, but I imagine if you were using this in an alpine scenario, it could be more comfortable with more layers underneath. The gear loops could use a bit more space. The upper loops don't come off the harness very far and it makes it hard to rack gear quickly. I really wish it had an auto lock (doubled back) waist strap. It's the old style that requires manual doubling back to close the system. Ill probably end up painting half the buckle red as a reminder. All that aside, it's doing it's job well enough, and I'm happy enough with it that I'll continue to use it. If you just want a comfortable harness to climb in? Maybe single pitch, or a few pitches? This is pretty great. Not too heavy considering the size.

Rated 5 out of 5 by from What hanging belay? My legs kept going numb on hanging belays in my Sama, so I went straight to the limit of harness comfort without getting a belay seat. Man. What a treat this thing is. The gear loops are staggered and plentiful. The long loop across the back is a great repository for emergency and seldom used gear that leaves the more accessible loops clear. Not as sweaty as I thought it would be thanks to the pillow padding, but you're definitely going to feel the heat of more coverage. Haven't personally had any cause to use the double belay loop, so I just stacked them together to keep the tie in points clear. Does make smaller carabiners a bit finicky to load, but well worth the comfort and carriage.
