At 8.7mm, the thinnest and lightest UIAA certified single rope in the world with a diameter of under 9mm, and a weight of only 51 grams per metre. Achieving these low figures was only possible by use of Mammut's Coating Finish®. During this finishing process, the individual fibres are stabilized with Teflon. This minimizes the abrasion between the fibres and improves slippage. The stress is evenly distributed to all fibres and the rope can withstand greater forces. This process improves the service life, optimizes handling through a uniform grip, and provides high dirt and water resistance.

In addition to the Coating Finish®, this rope is also dry-treated with Mammut's Dry process and therefore gives the best rope technology currently available.

It must be pointed out that Serenity is intended for use in on sight and red point climbing due to its reduced sheath proportion. This rope is not suitable for work-out climbing and top roping since these applications reduce the service life of the product considerably based on the increased material abrasion.

* Interestingly the diameter is given as 8.7mm for a single but 8.8mm as a double - this is because the diameter is measured under load and the loads differ for each test.

** Total weight of the rope may vary as the rope is often longer than the length stated.
