An ultralight rope built for alpine missions or demanding ice climbs, the Black Diamond 7.0 is a twin rope designed to be used in pairs. With a burly sheath that utilizes a 2X2 weave construction to withstand everyday use, the 7.0 is dry-treated from the inside out and can handle any weather you throw at it. The rope's middle marker is easily identifiable for rappels and the comfortable handling knots easily and feeds smoothly through a belay device.
