Over the years I've had a number of Black Diamond and Petzl harnesses. This one beats them hands down. It feels so light, like you're almost wearing nothing/ Before this I has been sceptical that 50 or 100g here or there in a harness made a difference, but it somehow does.But more importantly, even though it feels like you are wearing nothing, it somehow is the most comfortable harness I've worn. Taking falls, or hanging when you are trying to work out the next sequence, or belaying, it is just really really comfortable, with no individual pressure points. My partner, who got one after she had tried on mine, noted that it doesn't cause the same pressure in her hips like other harnesses do.I'm not a big reviewer, but I think this is such a great product that I ... MoreOver the years I've had a number of Black Diamond and Petzl harnesses.

This is a great harness. Perfect for the gym since it's a single adjustment and easy to put on and take off. I think if I was sitting in it for any amount of time, I'd prefer a 4 slide, but this is preferred for gym climbing. I have a 30" waist and the medium just barely fits, but works perfectly. If you have smaller than a 30" waist, I would recommend a small.

Caveat, I never actually used this harness outside, I only ordered and then returned it. The harness is well built, very lightweight, and comfortable. That much was obvious from putting it on at home.However two things were a deal breaker for me that I couldn't tell online. First the gear loops are pretty small. For sport climbing this harness would be great, but loading more than a light trad rack for multipitch climbing was way too tight. Second, the leg loops, while adjustable, cannot be undone, they are sewn into a loop that can change size, but cannot be undone (they also were pretty hard to adjust). For winter sports the harness I need to be able to undo the leg loops and waist to put it on over the my layers and boots.

Caveat, I never actually used this harness outside, I only ordered and then returned it. The harness is well built, very lightweight, and comfortable. That much was obvious from putting it on at home.However two things were a deal breaker for me that I couldn't tell online. First the gear loops are pretty small. For sport climbing this harness would be great, but loading more than a light trad rack for multipitch climbing was way too tight. Second, the leg loops, while adjustable, cannot be undone, they are sewn into a loop that can change size, but cannot be undone (they also were pretty hard to adjust).

I probably could have gotten away with buying a medium since I usually wear 32W pants in most brands minus a couple of high ends. So I was worried the Medium would have been small if I had added layers. So I ordered a Large. It’s not to big but the Sender has a retention band on the back of the adjustable(waist) clasp to allow the access to be stowed away which works. Great feel, super comfortable, great functionality, pre-shaped gear loops are perfect, adjustments are smooth/easy to use with gloves, and all around a great addition to anyone’s gear bag. 10/10 would recommend.
In general, super comfortable. Got this in XS, and I wear XS in the Ophir 3 Slide Women.I would have liked a ladies version, or at least have the option to extend the elastics going to the leg loops a bit longer since they ride up as is at the longest length.I would say the regular type of adjustable leg loops or the non-adjustable ones are more comfortable compared to the fast-adjust (where the straps are sewn into the leg loops dig into the side of the thighs, so longer leg loop padding would probably help instead if it has to be fast-adjust)
This is a great all around harness. Great for gym or crag. Gear loops provide more than enough space for trad gear & are built well. Harness is comfortable to hang in for relatively short periods of time (haven’t tested long time periods). Overall very happy with my purchase.
I probably tried more than a dozen of different harnesses. This is definitely the best one!The fit is great, the harness is flexible, shaping around your waist but still very supportive. It is on the light side, quite skinny but still comfortable to wear. I might need to do multi pitch to fully judge this aspect.The gear loop are slightly de-centred, which means that you do not need to fully close it to have the gear loop to perfectly line with your body.There are so many details that makes this harness the best of the bunch. The “wearing” warning, the protective plastic for the loop, the small elastic band to hold the extra comfort material in front of the harness (difficult to explain). The extra howl on the back for your chalk bag.The design is superb. I was ... MoreI probably tried more than a dozen of different harnesses.

I had to downside to have a good fit.To sun up, it’s a sport climbing harness that might suit many new trad climbers with the 5 small gear loop.
I love this harness. It’s a huge upgrade in my opinion from my black diamond solution harness. The solution feels super stiff compared to this harness, even with my solution being 2 years old. The front gear loops on this do a great job keeping QuickDraws in a nice front loaded position. My only two complaints are with the tie in loops, and leg adjustment buckles. The tie in loops are really small, and with my PAS and rope attached, it’s pretty crowded. The leg adjustment buckles are difficult to manipulate so I try not to adjust them if I can help it.
This harness is perfect for climbing short to medium pitches but once you have been in it for an extended amount of time it can get a little uncomfortable. I wore it while setting a top rope and was in it for over an hour and it was really comfortable for the time 30 mins but after that it started to be uncomfortable. But to about 90% of potential buyers this harness is perfect and lightweight for sport climbing. Also for figment I’m a 32 waist and I fit snugly in the small.
This waistband is more comfortable than all of my other harnesses, but the leg loops can ride up at times. The colour is beautiful, and it really is a breathable design.I only wished I got a medium instead of a large. The sizing chart might be off because my measurements should be for the large. However, it may be due to the stretchiness of the harness.Overall, this is a solid harness with vibrant colours and extra comfort. I use the front loops for my heavy gear. The back loops seem less strong than the orange loops, but they have also been able to carry a number of gear!
