LM DYNAMIC ROPES: Our dynamic ropes combine superior fall protection and abrasion resistance with great handling and flexibility to make the ultimate in climbing ropes. Available in 11mm diameter which is perfect for top roping, big walls, or when facing tough conditions, or 10.5mm diameter which is ideal for sport routes or when weight is a concern. Both diameters are available in a standard or dry finish. The dry finish helps retard the absorption of water by the rope, helps reduce friction, and keeps grit from entering the core of the rope. UIAA approved. Colors may vary.
