Measuring in at a svelte 8.9 millimeters, the super light Mammut Serenity rope is one of the thinnest single ropes around, with falls equaling that of larger rope. Ideal for those times when weight is a chief concern, you can add strength without adding weight thanks to Mammut's COATINGFinish technology.

Mammut's Serenity 8.9 Rope is an extremely lightweight rope for those times that speed and pack weight matter. The perfect rope for sport climbing and alpine pursuits. This small diameter rope with phenomenal glide is sure to become your favorite rope.
One of the smallest and lightest weight ropes in the industry, the Mammut(R) Serenity 8.9mm x 70m rope is great for speed climbs and longer routes when weight is a main concern. COATINGfinish(TM) process uses Teflon(R) to treat individual fibers, resulting in reduced abrasion, better load distribution and increased durability. SuperDRY(TM) sheath and core treatment discourages water absorption while resisting dirt and abrasion; Duraflex(TM) heat-treatment helps resist degradation over time. Kernmantle design combines a durable braided sheath and shock-absorbing core for reliable protection from fall forces. 8.9 mm diameter is light and flexible enough for difficult pitches yet strong enough to use as a single rope during longer sport and alpine routes. 70m length allows considerably longer leads and rappels. Includes Anti-Twist(TM) packaging to help uncoil rope smoothly and improve handling. Mammut Serenity Rope meets or exceeds UIAA tests for falls, impact force and elongation. Closeout.
