Petzl Sitta Harness

Designed for performance climbing and mountaineering, the Petzl Sitta is a lightweight and comfortable technical harness. With a thin and flexible waistband, it offers unparalleled freedom of movement for climbers and mountaineers. Even during hanging belays, it remains comfortable, allowing you to focus on pushing through crux pitches. This harness packs down small for convenient storage in your pack and features five gear loops for all your necessary equipment. Plus, the reinforced tie-in points provide exceptional resistance to rope friction for long-lasting use.

Features

Strikes the ideal balance between lightweight design, technical performance, and comfort:

• Weighs 275 g in size M, offering minimal bulk without compromising performance.
• Compresses compactly when stowed in its pouch, making it easy to pack.
• The exceptionally thin and flexible waistbelt and leg loops ensure unrestricted movement during climbs.
• Provides excellent comfort when resting on the rope or at hanging belays; utilises WIREFRAME technology with HMPE (high-modulus polyethylene) strands in the waistbelt and leg loops to distribute the load effectively without relying on foam.
• The interior fabric is breathable and wicks away moisture, enhancing overall comfort.
  
  

Designed to carry and organise gear efficiently:

• Features two very large, rigid front gear loops capable of holding a substantial amount of gear, allowing for smooth clipping and unclipping. Each front gear loop includes a mobile separator that divides the loop to optimise gear organisation (such as quickdraws, nuts, or cams), with the option to move the separator to the back to create one large gear loop.
• Two semi-rigid rear gear loops are angled to bring gear forward, maintaining comfort when wearing a backpack.
• A fifth semi-rigid gear loop at the back is easily accessible and ideal for attaching a tag line, shoes, a knife, or other accessories.
• Two slots are included for CARITOOL tool holders, optimised for CARITOOL EVO and compatible with CARITOOL models.
  
  

Built for long-lasting durability:

• Reinforced HMPE tie-in points enhance resistance to wear caused by rope friction.
• Bonded waistbelt and leg loop construction ensures superior wear resistance while maintaining a sleek, thin profile.
• The exterior fabric is designed to withstand abrasion, providing exceptional longevity.
• Supplied with a storage pouch crafted from recycled polyester and nylon.

BELAY LOOP AND TIE-IN POINTS: WHERE DO I ATTACH MY LANYARD, MY BELAY DEVICE AND MY ROPE?

The front part of a climbing harness usually has a belay loop and two tie-in points. These parts provide a place to attach a lanyard, a belay device and a rope.

1. Where do I attach my lanyard?

From a safety and strength perspective, the lanyard can be attached to the belay loop or to the two tie-in points. But as a matter of comfort, it is preferable to attach your lanyard to the belay loop.

	The lanyard attached to the belay loop helps maintain good harness geometry without affecting comfort. It allows the tie-in points to move freely and does not hinder the climber’s mobility. It also keeps the tie-in points clear, for attaching a single rope or two half ropes.
	A lanyard attached to the two tie-in points brings the upper and lower parts of the harness closer together. This reduces the climber’s comfort and mobility.

2. Where do I attach my belay device?

A common error is to attach the belay device to the two tie-in points instead of to the belay loop. WARNING: when connected to the two tie-in points, the carabiner will not be properly loaded.

	This attachment allows the belay device to move freely and helps prevent cantilever loading of the carabiner.
	WARNING: when the belay device is attached to the two tie-in points of a harness, the carabiner is not free to move and becomes loaded on the minor axis: There is a risk of the carabiner breaking if the climber falls There is a risk of the carabiner gate opening

3. Where do I attach my rope?

From a safety and strength perspective, there is no risk in tying in with a figure-eight knot or a bowline knot on the belay loop instead of to the two tie-in points.

But as a matter of durability and wear, it is preferable to tie in to the two tie-in points.

	The tie-in points were designed to be loaded frequently by the rope (repeated climber falls while working a route). They are reinforced with protective webbing and are thus more wear-resistant. Also, on certain harnesses, a red wear indicator incorporated into the tie-in points helps you know when the harness should be retired. This makes it easier to inspect your equipment.
	Tying in to the belay loop is reserved for mountaineering where falls are rare, as with the ALTITUDE and TOUR harnesses for example. Repeated falls on the belay loop when sport climbing will result in premature wear of the harness.

Once everything is set up, remember to do a partner check before starting to climb:
