The Fusion Photon is Sterling’s first half rope that is also certified to twin. It was manufactured to have a perfect balance of diameter to weight. Designed to round out the Fusion series as a performance half rope, the Photon is small and light, making rope drag less of a concern over long or windy pitches.
