Petzl Top Chest Harness

The Petzl Top chest harness is a chest harness that connects to a compatible Petzl sit harness. It helps keep you upright when hanging, spreads gear weight across the shoulders, and can be used to tend a chest-mounted ascender in rope systems.

What a chest harness adds

A sit harness alone lets you hang comfortably, but on long ascents or when working with a lot of gear it can be hard to stay upright. A chest harness like the Petzl Top connects to the sit harness and holds your torso in position. In single-rope systems it can also help set up a chest-mounted ascender or a rope-tending pulley.

It takes some weight off the hips too, which helps on long days with a full gear load. Browse more saddle parts in our saddle parts and shoulder harnesses.

Some climbers add a chest harness only for long single-rope ascents and leave it off for pruning days. It is easy to fit and remove, so you can match your setup to the job.

Fit, compatibility, and inspection

Use it only with the sit harnesses Petzl lists as compatible, and connect it exactly as the instructions show. A chest harness on its own is not a fall arrest harness, so check how Petzl rates the combined system before using it for fall arrest.

Inspect webbing, stitching, and buckles before each use, and replace any part showing damage. Climbing systems must follow the maker's instructions and ANSI Z133 practice, and you should be trained on any ascent system you use.
