Beal Rando 8 mm Twin rope (20 m, red/orange/pink) - Regardless of whether you need some psychological support for steep edges or a rope for high level walking, the Beal Rando 8mm twin rope is a great thing to have. With an 8mm diameter and only 37 grams per metre, it'll hardly take up any room in your pack, but it will provide the protection you need in the event of a fall.

Only the use of both strands can provide the necessary safety in the event of a fall.
