The Petzl Fly Harness is a minimalist, lightweight and innovative harness designed for technical mountaineering and ski mountaineering.
Ultra-lightweight, the Petzl Fly Harness can be put on with both feet on the ground thanks to its break down structure. Constructed without a buckle, the harness is compact and weighs only 130g (size M). The comfort foam is removable and can further decrease the weight to only 100g, allowing for a pure minimalistic approach. The multiple gear loops and the ice-screw retainers can transport all the equipment required on technical outings.
