The harness is the direct interface between the worker and the protection system.
All Petzl harnesses have adjustable shoulder straps, waist belts and leg loops. All adjustment buckles use the DoubleBack self-locking system. With this system, the webbing does not need to be rethreaded to secure the buckles - they can be adjusted with a single motion.
Certain harnesses are equipped with the FAST automatic buckles on the leg loops. Once adjusted, these buckles easily and quickly open and close - the harness can be put on without undoing all the buckles.
