The Petzl Mambo Standard Climbing Rope is the perfect choice for beginners who want to escape the plastic pulling gyms and get on some real rock. Its 10. 1 millimeter diameter is excellent for new belayers who need to refine their rope handling skills. Petzl equipped this rope with a thick sheath for enhanced abrasion resistance, an UltraSonic finish to eliminate frayed ends for better durability, and a ClimbReady Coil so you can uncoil it without any mistakes. All of these features give this rope an exquisite fall rating so you can climb with this rope for many years. The middle mark helps you find the middle of the rope for rappelling. Get the 50 meter rope if you still want to climb in the gym, the 60 for typical sport routes, or the 70 if you want to tackle some of the longest pitches out there.
