Engineered for fast-and-light ski mountaineering, split boarding and snowshoeing, the Flight 3 poles feature ultra light, aircraft-grade aluminum construction, a pack-friendly three-section shaft and ergonomic grips. Unlike friction-based adjustment-locking mechanisms that can sometimes slip, Flight 3 poles are built around our exclusive Sure Lock Adjustment System, which utilizes a positive-locking design for lightweight, reliable performance and confidence on challenging terrain.
