Harness for pros and experts, for intensive use on any terrain.

High end climbing and mountaineering harness, offering maximum compactness, light weight and comfort. The WIREFRAME Technology construction of the SITTA harness uses Spectra® strands in the waistbelt and leg loops to ensure optimal load distribution and excellent comfort. This highly technical harness gives the climber total freedom of movement.


WIREFRAME Technology construction:
- Spectra® strands are used in the waistbelt and leg loops to give optimal load distribution without the use of foam
- the extremely thin waistbelt and leg loops offer a sleek design, with compactness and light weight pushed to the maximum.
Comfort and durability:
- the use of bonded fabric in the waistbelt avoids pressure points and gives optimal wear resistance
- the lack of through stitching eliminates chafe and pressure points in the waistbelt
- the elasticized fixed leg loops and very supple leg loop bridge give great freedom of movement
Easy adjustment:
- DoubleBack HD buckle in forged aluminum has a slim, rounded design that offers good handling and smooth strap glide for quick and easy waistbelt adjustment.
- the ribbed adjustment strap helps prevent accidental loosening
Fully equipped:
- reinforced tie-in points in high-tenacity polyethylene for improved resistance to wear from rope friction
- two rigid high-capacity front equipment loops
- a removable separator for organized racking and quick and easy access to your equipment
- two supple rear equipment loops to avoid creating pressure points when wearing a pack
- two integrated CARITOOL tool holder slots
- rear loop for haul rope
Eco-designed harness, made with Bluesign fabric, which respects the objectives of optimizing resource productivity, consumer safety, professional hygiene and security, and of reducing air emissions and water pollution.

Weight (g)


In grams, the weight, as stated by the manufacturer/brand.

If there are differences in weight (due to multiple sizes or optional accessories) we'll list them here.

The default weight is the middle-most size, often this is size M.

270 g

S : 240 g / 8.5 oz
M : 270 g / 9.5 oz
L : 300 g / 10.6 oz

Gender Unisex
Sizes XS, S, M, L, XL
Gear Loops

Number of Gear Loops

Gear loops are used to hold gear (quickdraws, cams, etc) onto your harness. 4 gear loops is most common.

0 - 1 Gear Loops

Most often on full body harnesses or guide/gym style harnesses.

2-3 Gear Loops

Mostly found on lighter harnesses made for [ski] mountaineering or high-end sport climbing where weight is a high priority.

4 - 5 Gear Loops

The standard/most common number for climbing harnesses. Perfect for sport and trad.

More Than 6 Gear Loops

Designed for long multi-pitch and big wall climbing, found on harnesses made to hold the maximum amount of gear.

Worth Considering

Occasionally, the number of gear loops will change on a harness model depending on the size. There could be 7 gear loops for the med/large but only 5 gear loops for the xsmall/small. In this case we list the highest number for the filters, and then write an explanation on the product page like, “Size S/XS can only fit 5 gear loops.”

4 Gear loops
Ice Clip Slots

Ice Clip Slot

Ice clipper slots are made to fit a carabiner that holds ice screws. These slots are generally only used by ice climbers but there is no disadvantage to having them on your harness.

Less than 40% of harnesses will have ice clipper slots. And those harnesses will usually have 2 or 4 slots, often located next to, or between, the gear loops.

Haul Loop

Haul Loop

Trad climbers often look for a haul loop as they're intended to haul a rope (second line) or pack (while you climb the chimney).

A haul loop can also hold shoes or other accessories. Although not the intended use, it is also commonly used to hold a chalk bag.

Climbing Gear Review no rating given just a review

“Lightweight harnesses aren’t supposed to be this comfortable,” one user said after a few whippers on the limestone tufas of Kalymnos, Greece. The wireframe technology uses Spectra strands as the skeleton, which run through the entire waistbelt and leg loops, and with a bonded fabric and no stitching on the outer material, testers found that the Sitta (9.5 oz.) was just as easy to wear as a fully padded big wall rig. Removing the foam makes it twice as packable, squeezing down to about the size of your morning cereal bowl. Indian Creek testers lauded the removable plastic separator on the front two gear loops, which organized gear and upped stiffness, making it easier to grab and go in terminal pump situations.

Alpinist Gear Review rating 5/5

Overall, this harness is an improvement over the Hirundos, Petzl's ultralight harness that's been on the market for several years. While it won't replace the harnesses in my closet, I found the Sitta to be versatile and will continue to wear it climbing. I'm excited to use it this winter while ski mountaineering and next summer while alpine guiding.
