The Petzl FLY is an ultra-light ski mountaineering harness designed for speed and efficiency. Weighing just 100–130 g, it offers modular comfort, fast donning over skis or crampons, and essential gear organization for alpine missions.
The Petzl FLY is the lightest harness in the Petzl range, designed specifically for technical ski mountaineering and fast-and-light alpine missions. Its minimalist, body-hugging design prioritizes freedom of movement, making it feel nearly imperceptible during high-output activities.
Engineered for efficiency, the FLY can be donned while wearing skis or crampons, offering quick transitions in demanding mountain terrain. Its modular construction allows users to remove foam padding from the waistbelt and leg loops to further reduce weight or retain comfort when needed.
