Designed for mountaineers and ski mountaineers, the Fly harness is Petzls most lightweight harness, and can be donned with both feet on the ground. Ultra-lightweight and compact, thanks to innovative construction without a buckle and with comfort options, it weighs only 130 g (size M). The comfort foam is removable, minimizing weight to only 100 g. The multiple gear loops and the ice-screw retainers can transport all the equipment required on technical outings.
