The Petzl FLY Harness is an ultra-lightweight, minimalist climbing harness designed specifically for technical mountaineering and ski mountaineering. Built for demanding alpine objectives where every gram matters, the FLY can be put on while wearing skis or crampons, eliminating the need to remove your equipment before gearing up. Its close-to-body design provides exceptional freedom of movement, while the removable comfort foam lets you choose between minimum weight and increased comfort.

At just 100 g in size M without the foam and 130 g with the foam, the Petzl FLY is designed to feel almost imperceptible during technical outings. Its minimalist storage pouch also compresses the harness to save valuable space inside your backpack.

Adjustable Comfort and Lightweight Design

The FLY features Petzl’s innovative buckle-free construction, replacing a conventional metal buckle with a sliding toggle lock for quick and easy waistbelt adjustment. The leg loops are adjusted using a girth hitch, helping maintain the harness’s minimalist design.

Petzl’s FUSEFRAME Technology incorporates removable foam in the waistbelt and leg loops. Keep the foam installed when comfort while hanging is a priority, or remove it when reducing weight and pack volume is more important. The foam distributes load effectively for improved comfort during hanging belays and technical climbing.

Technical Gear Organization

Despite its minimalist construction, the Petzl FLY Harness provides useful options for carrying essential climbing equipment. It has two gear loops and four additional loops for organizing technical gear. Each leg loop also features a silicone-lined retainer designed to hold an ice screw securely.

The attachment points, webbing and gear loops are reinforced with HMPE (high-modulus polyethylene) to improve resistance to abrasion and rubbing during demanding alpine use.
