The Edelweiss Energy Arc 9.5mm Rope is a bi-pattern rope for advanced climbers. The thinner diameter makes it more advanced, while the bi-pattern makes it super easy to tell right when you've reached the middle of the rope. The rope weighs in at a mere 58g/m, so you can fly up the climb without dragging any excess. Thanks to HD cover Technology, the sheath is strong, supple and ready for easy handling. Head on up, little mountain goat. Final SALE: For safety reasons, we cannot accept returns on load-bearing Climbing equipment. Sorry for being so mean.
