The Petzl Scorpio Vertigo via ferrata lanyard is designed specifically for use on via ferrata routes. The lanyard arms are elasticated to keep them close to your body, prevent tangling and reduce the risk of tripping while you're moving. The tearing energy absorber is in a protective pouch with zipper for ease of inspection. The Petzl Scorpio has a special extra attachment point which is really useful to clip-in to rest or when traversing. Included are two Petzl Vertigo WireLock karabiners designed specially for via ferrata with extra strength, a wide gate opening (for clipping over rungs and cables) and for fast and easy, one handed operation. The Petzl Scorpio is best attached to the harness using a simple lark's head hitch and doesn't require any additional hardware.
