The Sterling Fusion Photon is Sterling’s first half climbing rope that is also certified as a twin. It was manufactured to have a perfect balance of diameter to weight.
The Photon was designed to round out the Fusion series as a performance half rope. With a diameter of 7.8mm and weighing only 41 grams per meter, the Photon is small and light, making rope drag less of a concern over long pitches.
