    Light on the approach, compact in packs, and comfy on hanging belays.

    WireFrame Technology makes the Sitta Harness Petzl's lightest and most compact harness for high-end climbers and mountaineers. WireFrame uses small Spectra strands in the waist and legs for optimal load distribution and a surprising amount of comfort. The self-locking waist buckle stays secure, and the elastic leg loops accommodate bulky mountaineering gear or slim climbing shorts. There are four flexible gear loops that stay compact in your climbing pack, two ice clipper slots for Petzl's Caritool holders, and additional loops that are perfect for chalk bags, cordelette, anchor systems, or belay devices.

    Lightweight, Get Correct Size

      The super cool thing about this harness is how insanely light it is. If you size it right it is also pretty comfortable. I will say that I do prefer something a little bit more adjustable because after a bit of belaying or on your descent it tends to ride up a little bit. Overall this was a pretty sweet harness and it didn't ever weigh me down. There are plenty of organizational features on the gear loops so you will have no issue there.

      Extremely light

      • Familiarity: I've used it once or twice and have initial impressions

      This harness is about as minimalist as it comes. Its not particularly comfortable, but if you're looking to reduce weight on the wall or save space in you pack, this is your harness. I particularly enjoyed the two front gear loops, which are great for organizing your rack.

      Spiffy, not durable, size right

      • Familiarity: I've put it through the wringer

      I climbed exclusively in this harness for ~2.5 years on sport, trad, mountains, ice, and some plastic. After that time, the harness's weaknesses cropped up and it is starting to breakdown. Overall this harness is great for its features, packability, and weight. It is bad for its comfort and durability.

      This was pretty tricky, like many harnesses. With this one you want some extra room for winter layers. I'm 5'8, 140-150 lbs, 29-30 in waist. I wear prana zion stretch pants in 28in waist (30 is waaay to big), and jeans usually with room in 29-30 in. I'm usually a Small in most things, but here the S would have put me at the highest end of the spectrum, so I went with a M. I was often wishing I could tighten the harness more like this, but I was happy with winter layers on. Hard compromise.

      Good: The gear loops are great; large and rigid. It packs quite small, although by folding it together to fit into the sack, you put a good amount of stress on the gear loops, which is a disappointing weak point. The harness is comfy to climb in.

      1. Comfort. The spectra fibers spread out in the middle, but at the edges of the harness waist they com together at a single point, making a knot/rigid bulge. With my sizing, I found that this bulge often created a pressure point that was very painful when hanging in the harness. If not for this, the harness would simply be impressively comfy for how small and light it was. Again, sizing is key, which sucks since you can't return these and stores are getting in short supply.
      2. Durability. The first points to die were the elastic cords that attached to the leg loops, which are shockingly important for the harness. Without them, the harness is terrible to walk or climb or exist in. You need those straps. These straps quickly wore out at the attachment point with the leg loops. The new version might be a bit better, but that sucked. After 2.5 years, these cords blew out, and Petzl stated that this was outside of the warranty. Pity, since otherwise the harness still has a lot of life. The other place that wear shows early is the gear loops. Imagine losing your rack 10 pitches up! I think this is largely because of the stress put on the loops during storage.

      Verdict: this this is damn expensive and doesn't last well. I would strongly suggest not trying to use this harness as a quiver-of-one harness. Get a more durable harness and save this one or the similar BD harness for the alpine missions. I'll be looking to get a different harness next.

      Awesome first experience!

      • Familiarity: I've used it once or twice and have initial impressions

      I had the chance to try out this harness for my first couple days rock-climbing and loved it! The medium was a great fit for me (31" waist). As someone new to climbing, I appreciated the sturdy simplicity and comfort of the Petzl Sitta.

      Awesome first experience!

      Sport harness

      • Familiarity: I've used it several times

      Great harness for hard sport climbing. Lightweight and small. I've worn the hirundos for many years and this is on par with the quality from other Petzl Harnesses

      Light, compact, comfy

      • Familiarity: I've used it several times

      Excellent for mountaineering. So light and small in pack. Used it sport climbing a bit too and was comfy in a short multi-pitch. Saw some other mentions that it is delicate outer which can shred if pressed against rock. I don't doubt that, but I haven't been in that situation with it so it's been fine for me. If you're gonna be shredding it against rock, maybe a more durable (but heavier) material will be more resilient. If you're carrying an alpine harness or for some climbing that won't be shredding it against rock over and over, it seems great.
      I would normally be a small, but in reading other reviews, I went for an M and that fits fine at its tightest (could be **slightly tighter) but allows for extra room if with layers. I'm skinny and leg loops are snug but not uncomfortable, but I've heard they can be too tight on folks with thicker thighs.

      Comfy, lightweight and a favorite

      • Familiarity: I've used it several times

      The Sitta is ultralight and incredibly comfortable. It has all the gear loops you'll need from Sport to Trad leads. Being super light, as with most gear, does mean it is not beefy and super durable. If you're looking for that in your harness look for a more burly option. If you're looking for shedding weight staying comfortable while also keeping the features you need then get the Sitta.

      Comfy, lightweight and a favorite

      Sitta Comfortable, Not Durable

      • Familiarity: I've used it several times

      Bought Sitta in August 2017. Worn weekly, some outdoor, mostly in gym and recently during climbing trip to Red Rock Canyon in Nevada. After trip, I noted bottom of right leg loop frayed, exposing sharp plastic ridges (we climbed only 5 routes up to grade 5.7). Assume rappelling resulted in fraying (rope usually on my right side when rappelling) Concern fraying will worsen during outdoor climbing this upcoming season (thus, potentially cutting into rope, slings and clothing). Believe this may be a design flaw since Sitta harness described as high-end climbing and mountaineering harness. Petzl will not refund or provide an exchange.

      Great - but fragile

      • Familiarity: I've used it several times

      Everything you have read about the harness being light, comfortable, barely there, fantastic gear loop dividers etc - are all true. However this harness survived just a few days of ice climbing before the clipper slots started tearing - much to my severe disappointment. Also the slots are poorly located, being inside the gear loops, instead of the being between the gear loops - similar to almost any other harness on the market. I have spoken to others who have trashed the harness chimney climbing in a single day - the material the harness (besides tie in points) is mostly constructed of is just thin ripstop. I am going to attempt to get a warranty claim for the harness, but I am unsure if I will keep it even then.

      Lightweight with terrific mobility

      • Familiarity: I've put it through the wringer

      There are a tons of things that are more important that having a light harness. That said, the Sitta is by far the lightest harness that I've ever climbed in, and I appreciate the minimalist design.
      Petzl produces lots of really quality gear, and the Sitta is unsurprisingly well-made/durable. I haven't necessarily put mine through hell, and I am sure that there are foreseeable scenarios that might test my assertion of longevity, but so far it has held up through both winter and summer use.
      I don't love the gear loops - the rear two feel pretty far out, and the dividers on the front two aren't all that helpful - still, they work!
      If you're looking for a super lightweight, versatile harness with great mobility, the Sitta is probably worth checking out.


      • Familiarity: I've used it several times

      Wore this out for a few weekends in Indian Creek, climbing everything from tips splitters to offwidth. The harness was very comfortable and extremely light, offering a ton of mobility. The low bulk was nice in OW. The fabric held up well against the sandstone and didn't show much pilling or signs of abrasion, though I could see the material getting pretty beat up if used as a daily driver.

      I wasn't a huge fan of the gear loop divider, which made it hard to pull gear with the opposite hand. Luckily this could be moved out of the way, making for a standard loop. I also found the rear gear loops to be too far back, making them hard to reach. May just be something that takes a little time to adjust to .

      All in all, a very comfortable and lightweight harness that I would wear on all types of terrain.

      Light and Dependable

      • Familiarity: I gave it as a gift but have feedback to share

      I bought this as a gift for a friend and this is what they had to say:

      "This is the second harness I've had, and so far it's comfortable, light, simple, and effective. I've used it for sport, lead, and alpine/ski mountaineering over the past month.

      It's packability is great for ski objectives where it hides away in my pack and can come out if needing to hook into my axe or rappel into a line. My waist is 32, and the medium fits great, with room to maneuver the leg loops over my ski boots.

      I've taken a few small falls on it, and it's held up well as has my back/waist. I have yet to do any hanging belays on multi pitch, but I suspect it will be relatively comfortable.

      I have yet to do any lead climbs on trad, but for sport routes the gear loops have been greatly positioned.

      In an attempt to have one harness to do it all, so far it's perfect. It's effective and so small and light I hardly notice I have it on."

      Best of the Best

      • Familiarity: I've put it through the wringer

      Whether you are sport climbing in the Red River Gorge, climbing the Eiger, climbing ice in Ouray, or bagging towers in the desert.. This is THE harness for it all. If you are weight conscious but also want a comfortable, durable harness then look no longer. The Sitta is what you want. It is packable, light weight, durable, and built for any of your climbing or ski-mo needs. The Sitta is comfortable even when giving long belays to your partner as they work through their project. I would recommend this harness to anyone looking for a versatile harness for all their climbing needs.

      Best Petzl Harness Yet!

      • Familiarity: I've put it through the wringer

      I absolutely love the Sitta Harness. the lightweight design makes me feel as though I am Sport Climbing without a harness at all. The Leg loops are super comfortable, even when you are hanging up on a project for an extended period of time. I also really like the nifty little brush holder loop on the left side of the waste-band! I don't think I'll ever be able to use any other harness again, because nothing compares to the SITTA!

      My new favorite harness

      • Familiarity: I've put it through the wringer

      I have been super impressed with the Sitta harness and despite its lightweight design, it is still very comfortable. In particular, I really like how the rear straps are so stretchy and low profile. I barely notice them when I am climbing. I also really like the construction of the gear loops. They are large enough to hold a full rack and are positioned an ergonomic way, allowing for ease when grabbing things off the gear loop or re-racking while cleaning a pitch. I have been using the divider in the front gear loops and like how this feature keeps the gear a little more organized and does not allow all the gear to slide to front of the loop. It is nice to have gear that serves multiple types of climbing and this harness works great for sport, trad and alpine climbing!

      Most comfortable harness I've used

      • Familiarity: I've put it through the wringer

      I've been using the Sitta harness almost daily this winter, and it is the most comfortable harness I've owned. I was immediately psyched at the weight and packability, but wasn't sure that it would be great for hanging belays. After a full winter of use, hanging at belays on steep climbs, the Sitta is comfy all day long.

      The gear loops are well placed, and I do use the splitter on the front loops to keep longer draws and slings from falling forward. The 2 Caritool loops are in good spots, although I would like to see an option for two more. The back loops lie flat, and it took some use before I trained myself to clip blindly on the back. Now it is second nature.

      I have a 32

      I'm a 29" waist with a 20" legs. Should I go with a medium considering clothes

      Hey Martin,

      It looks like the Medium is going to be the best fit for you. If you go with the small, with clothing considered, the leg loops will be uncomfortably tight.

      If you have more questions on this harness, or any other climbing gear, please don't hesitate to shoot me a message.
