This ultralight harness (139 grams in size S) is ideal for rock or indoor climbing. Extremely versatile and efficient, it is also ideal for mountaineering and ice climbing.

The Addax makes no compromise on the quality of its functional elements: four large gear loops, two waist belt ice screw slots, comfortable padded leg loops and a waist speed buckle. The seamless "Magic Ring" belay loop also offers more lightness and friction resistance.

It is a harness for experienced climbers looking for minimum weight without giving up comfort and sturdiness.

My new "Go To"

I purchased this harness only about a month ago, just enough time to test it on ice and have used it now about 5-6 times on rock and I am a convert.

Lighter than the Sitta which is ridiculous but what really sold me on this harness was the position of the ice screw slots; they are exactly where I want them to be! I have found with the other harnesses I have used over the years that the ice screw slots are positioned too far behind the hip requiring yogic moves while balanced on one tool (not something that inspires confidence). With the Addax, a simple twist and there they are! Fire that screw and go!

The harness packs small and light, it is remarkably comfortable despite its minimalist design and the gear loops are functional and well designed. Whether you are sending the frozen blue or the steeps at Rumney, this harness can do it all and do it well!

The Addax is an amazing harness. I've used it for everything from high-end sport climbing, to multi-pitch rock routes, to huge alpine missions. It is unbelievably light and packable, yet remains comfortable when at hanging belays. Often, gear loops are compromised on light weight harnesses- not so with the Addax; they remain very usable, even with a larger gear rack and backpack on. This is my go-to harness for any for of climbing in the alpine. Bravo!

Simple and functions very well

Like others mentioned, it's barely noticeable. Comfort is adequate for such a minimal piece of equipment. While I wouldn't want to hang in it for extended periods of time (at a hanging belay, for example), for a normal outing of projecting on sport routes it was great. The elastic in the leg loops is just enough to keep it in place. I appreciate the replaceable elastic in the back. The gear loops are great for keylock gates, but I reckon I would snag notched noses to more frustration. Loading more than 8 quickdraws on the sides is where you start to feel it. A small gear rack would be fine. A note on sizing: I feel that it runs a bit big. I maxed out a small whereas I have a cm or two in a small Sitta or Hiundos in. So my recommendation would be to size down if you are in between.
Overall, this seems like the best value on super lightweight performance harnesses.

I like it!

I’ve been wearing a Petzl Sitta as my main harness now for three seasons. I wanted something even lighter for long approaches and multi day trips in the hills. This harness is awesome. Every bit as comfortable as my Sitta and even lighter and more compact. I don’t rack huge amounts of gear on it, I’m old and mostly use a gear sling, but it carries what I have put on it well and it just seems to disappear when wearing it. Only minor change I’d like is the leg loops are a bit large, even with my skier thighs. Still it’s a great harness for backcountry climbing.
