Lightweight and decently comfortable
I did not get this harness specifically just for comfort as I wanted a harness that would feel like I wasn’t wearing anything. So far after having if for over a month I am extremely happy with how it has performed. The material is comfortable and breathable, the gear loops are strong and can fit a lot of gear, and while climbing it barely feels like I have anything on. I did notice a bit of inner thigh rubbing while belaying and tugging from the rope, but it is not quite bad enough to make it worth looking at something else. I believe the slight sacrifice in comfort was well worth it for weight savings.

Built well, adjustable, minor flaws
Ive had this harness for about 10 months now, and in terms of build quality it has really held up against use 2-3 times a week at my climbing gym. The reinforced hardpoints are good for adding durability, and the gear loops are substantial and allow you to carry quite a bit. I will say though, like another reviewer mentioned, I have problems with chafing when I am belaying for a long time, which has gotten quite annoying during long sessions, or when I am wearing thin pants or shorts. Would recommend for quick casual sport or gym sessions, but you might want to look elsewhere for long sessions or multipitch outdoor climbing
Great Harness
I’ve used this harness inside and outside, and I’ve loved it so far. It has a ton of adjustment, and fits perfectly where others might not adjust as well. It’s pretty light while sacrificing little. The comfort is pretty good, but after projecting for a while and taking a few falls it can start to bug you a bit but nothing to complain about. While belaying it also works very well, but same goes if the climber is projecting.

Great harness and comfortable
We have this harness in two sizes and it works well for both of us. After trying several models on, my climbing sorter ultimately went with this model. We both like the fit and comfort of this harness. Currently being used as a gym harness, but looking forward to testing it outdoors in the spring. The adjustment options, particularly the ones for the leg strap are great and was one of the big reasons for choosing this model over others. I climb regularly and it’s holding up well. The mesh bag is handy and is used for storage in a larger pack and it’s money! Saves so much space and keeps things together.
Great Quality and Low Price
I've had this harness for about a year now and have had zero issues, the padding in the waist and leg bands make it very comfortable, I would recommend it to anyone. Some things to know about it, however, is that I find the waist runs large and the leg loops a tad small, so I might recommend a women's harness if you're also a bottom-heavy gentleman with a thin waist (women's harnesses have tighter waistbands and more space in the leg bands, typically). I'm a medium sized person and my medium sized harness needs to have the waistband fully tightened and the leg loops almost fully open. No complaints, since it still fits, but just something to take note of. There's more than enough space in the gear loops for a rack. A double rack would be tight, but doable.
Mammut Men's Ophir 3 Slide
I am 5'11" 160 and the medium is too large. For a good fit, I have to pull the waist buckle tightly. The harness is comfortable when not weighted, almost feels like there is nothing there or restricting your movement. However, hanging is not ideal and will cut off circulation. Although this is not a big wall harness or specific for trad so not surprising or that much of a negative. I do like to take pictures of climbers so this was a little annoying when my legs are going numb. The Loops are not large but if you rack smart you can fit a double rack without too much trouble. It's a small and light profile which is nice and of course, it's one of the best-looking harnesses!
Excellent all around harness for trad and sport
After other brands always misaligned the gear loops on the left and right side I decided to try this one even though it has a single buckle closure on the waist belt. Fits perfect and the gear loops are finally not lopsided. I hang a lot in my harness developing routes. This harness is very comfortable and breathes well. It's wide enough for great support when hanging. I don't notice it getting in the way when climbing like my big wall harnesses do. Adjustable leg loops work well too. Over all an excellent do it all harness if you like a variety of climbing including sport and trad. Gear loops stick out well and are easy to clip. Probably over kill for just sport climbing unless you hang dog all day. In which case you should lower off and give someone else a go any how. :-)
It's a great harness
I have ran through my previous orphir 3 slide and it is a fantastic overall beginner/intermediate harness. Overall use it for gym and outdoor climbing. I am more into comfort padded climbing harnesses vs lightweight and non adjustable climbing harnesses. The adjustable leg straps and hip are great and can fit me and friends if they borrow the harness. I like the wear stitching being bright red and easy to locate/see is fantastic. I also love the semi hard gear loops they can fit all my quick drawers and climbing gear when outside. Overall would definitely recommend this harness to anyone looking for a comfy great harness.

Sturdy and Plenty of Gear Space!
I used this harness one day when getting our climbing wall set up (at the summer camp I work at) because I didnt bring my own that day. Next thing I know Im buying one. Its hard to say exactly what it is but this harness just feels good. The stiff gear loops make it easy to grab or store gear, the belay loop and harness loops are easy to access and feel great. The harness adjusts well and sits well! While its no arborist harness that you can hang in all day, it feels great when on the wall and rappelling. Its lower profile than my first harness and overall just feels trustworthy. love Mammuts design for this one.

Pretty Happy
First harness I have ever owned. I'm 5'8" about 175 with a 34 waist. I purchased mine in store and tried it on. Definitely try it on beforehand. Make sure it fits! Ended up with a size large. So far, I like it a lot. I like that the leg loops are adjustable which is not always the case with other harnesses. Comfortable, even when hanging for a while. I don't have a ton of extra hardware, but the equipment loops are nice for the few things I do have. No complaints.
