Mammut Serenity 8.7mm x 80m DRY


The Mammut Serenity 8.7mm is one of, if not the, world’s thinnest and therefore lightest, single climbing ropes. With the new 8.7 Serenity, Mammut is once again proving exactly what is possible in the area of high-end ropes.

The super thin diameter and incredible weight make the 8.7mm Serenity an ideal choice for ambitious sport climbers looking for a rope to red point at their absolute limit. Despite a relatively durable construction for its diameter - with a high proportion of sheath - this rope is not suitable for concerted abseiling or top roping. As well as meeting the standard for single ropes, the 8.7 Serenity also meets requirements for half and twin ropes and is therefore suitable for mountaineers looking for a versatile and light rope.

Make the Mammut 8.7mm Serenity your secret weapon of choice for that successful onsight, flash or red point ascent.

Mammut Rope Finish - DRY™: Innovative technology and the highest protection level offered by Mammut. The ropes of the DRY™ line combine coated yarns, a unique 'Coated Core Technology' and lastly a coated sheath to minimise water absorbency to no more than 1% of the ropes overall weight. This line by definition will also maximise the rope's lifespan by protecting it from dirt and grit infiltration.
