Swiss Quality

Swiss Quality

Those who trust their lives to Mammut ropes justifiably expect the highest quality. We are fully committed to meeting this expectation. All our ropes are manufactured in Switzerland. Every day Mammut processes a quantity of polyamide fibers that, if lined up end to end, would encircle the globe once.

Meter by meter, we check electronically for any irregularities, and we regularly test the performance of our ropes on our in-house drop test tower. Our ropes fulfil the strictest standard requirements, giving performance reserves that far exceed those required. A Quality Management System in accordance with ISO 9001 standards guarantees  exceptional quality in every  rope. In product development work, we carefully monitor our ropes’ realworld performance. Mountain guides  from the alpine federation training teams, professional and top climbers and last, but not least, our mountain crazed employees, mercilessly test Mammut ropes in demanding conditions before a new rope goes on sale.

Rope Production

Every Mammut rope is manufactured in Switzerland. Mammut uses high quality Polyamide 6 (Nylon) filament yarns.

Several yarns are spun together to make a twine. Three twines are then combined to form a strand. A number of these strands form the core of the rope.

The sheath twines are braided around the core strands on the braiding machine.

Every single meter of rope is checked electronically for any inconsistency. In Mammut’s test lab and drop tower every single production batch is tested for all relevant specifications to maintain consistent performance standards.

Where the difference lies

It’s not only «Swiss quality» and one hundred percent dependability over a long life span which sets our ropes apart. Our research engineers are continually developing innovative solutions that make Mammut ropes «State of the Art», and which have earned us many awards in neutral tests in the past.

Mammut® Coated Core Technology

The individual core strands are given a Coatingfinish™ and a thermal treatment before braiding. This finish gives the core strands lasting and effective protection against water and dirt. This reduces friction between the strands and improves its sliding properties. When loaded, e.g. in the case of a fall, the force is evenly distributed across
all core strands and the rope can perform at its best. Mammut‘s® Coated Core technology is exclusive to DRY ropes.

Mammut® Coated Sheath Technology

The rope sheath is given a Coatingfinish™ and a thermal treatment after braiding. This thermal treatment results in a significant increase in rope performance:
The rope can cope with one to two more standard falls than a rope of the same diameter without additional finishing and also offers pleasantly smooth handling.
The rope sheath coating also leads to significantly
in­creased abrasion resistance and gives the rope dirt
and water-repellent properties.
Mammut’s® Coated Sheath Technology is used for PROTECT and DRY-Ropes.

Rope ends

Mammut® rope ends feature durable ultrasound welding, which prevents separation and sheath slippage as a result of use.
The thermal transfer label on the rope end provides the key information for each rope.


Every Mammut® rope includes an Info-Tex tape in the core. This tape includes key data, e.g. manufacturer, test standard, production
date and test location. This means that it is always possible to prove the original tested quality of Mammut® ropes.

Rope length

Every rope shrinks when used. In extreme cases it can shrink up to 10%. In order to guarantee the specified length when buying a Mammut® rope, all Mammut® ropes are made 2.5 % longer.

Sheath component

Mammut always tries to achieve a balance between low weight and a sufficient sheath component – after all, the sheath is responsible for the durability of the rope.

Center marker

All dynamic ropes by Mammut feature an abrasion-resistant color center mark. When selecting the method, special attention was
paid to choosing a dye that does not weaken the sheath or core.


The braiding of ropes with the Duodess design changes in the middle; this guarantees a durable, clearly visible center mark.

BiCo Sense

BiCo Sense technology uses a slightly bigger sheath twine in the rope core. At precisely defined locations – just before the end of the rope and the rope center – this special sheath twine changes from inner core to outer sheath. The stronger sheath twine is then tangible and draws the attention of both the belayer and the climber to critical areas of the rope, both visually and by touch.

Double Twist

Double Twist braiding uses not just two, but four sheath twines in parallel. This gives the rope a very uniform surface and incomparably smooth handling when in use.

Lap coiled

Tangle Free Ropes

A further innovation of the Mammut Rope factory is the «Lap Coiled» coiling technology. Thanks to the first fully automatic «Lap Coiled» rope packing machine, Mammut ropes have additional safety and comfort advantages.

Up until now, it was necessary to very carefully unroll a new rope, rather than simply uncoiling it, in order to keep it from becoming twisted. The technique is not easy to learn and must be done correctly to prevent tangles. For lead climbing, top roping and abseiling (rappelling), tangles in the rope are a hindrance and can be dangerous as they make handling difficult. When a rope has tangles, they must be worked out by hanging the rope and allowing the rope to untwist naturally. Thanks to the new «Lap Coiled» technique in the production, the uncoiling process no longer introduces the twisting that leads to tangles.

The heart of the new machine is a new technique for coiling the rope. Instead of coiling it as in the past, a seven-axis programmable robot arm lays the rope in a figure eight form. Ropes up to 100m long can be coiled in this way without introducing a twist. Safety marking and strapping of the finished rope are integrated into the automated coiling process. Due to the multiple stage quality control steps, the renowned Mammut quality is guaranteed.

Now, you can simply open your pack, tie in and climb!


Standard Test Requirements

Internationally accepted standards guarantee that only safe equipment is allowed to be sold. Naturally each of our ropes not only fulfils, but exceeds both the EU rope norm EN 892, and also the stricter UIAA standards. But what do the various standards and symbols stand for?


The Euro Norms have been especially tailored for products to be standardized. Therefore, a symbol is always accompanied by the number of the norm, (for dynamic ropes – EN 892; for static ropes EN 1891). Products which display the EU norm symbol fulfill the safety requirements and must have passed a production-sample test at a recognized test center.

CE-Conformity Symbol

This symbol shows that the manufacturer recognizes his own responsibility; it is not a quality symbol, but rather a type of passport for that product within the European Union. It means that the EN standards for product security are maintained. The number after the CE symbol (e.g. CE 1023) indicates the batch number or the standard/directive.


Products which display this symbol fulfill the requirement standards of the UIAA. The UIAA, the International Union of Alpine Associations, has for decades pioneered the development of practically oriented standards. Therefore, in most cases, the UIAA-standards are somewhat more stringent than the Euro standards. All Mammut ropes fulfill the most recent UIAA requirements


The ISO (International Organization for Standardization) combines the united world-wide national normative organizations. The ISO Norm 9001 defines overall process rules for Quality Management. They maintain the continuous quality of products and services. Certifying is conducted by an external body for example the B.S.I.


Rope diameter is measured under a 10 kg load. Under test, some ropes on the market clearly deviate from the manufacturer’s data.In practice the diameter has little meaning. Only the clamping effect of particular braking devices or belay devices with thin ropes should be controlled (with back up safety). The advantage of thinner ropes is normally reduced weight and friction.

Weight per Meter

Normal single ropes weigh 51 to 70 grams per meter, half ropes about 45 grams and twin ropes about 40 grams. Just two grams less weight per meter already reduces the pack weight of a 50-meter-rope by 100 grams.

Falls Held

The drop test is the point of most interest. It measures how many standard falls a rope will withstand. The standard fall with a fall factor of 1.75 is an extremely hard one, which  very rarely occurs in practical use. A weight of 80 kg (with single and twin ropes) or 55 kg (with half ropes) falls on a single cord (single and half ropes) or doubled cord (twin ropes). Single and half ropes must withstand at least 5 standard falls, a doubled twin rope at least 12. Single ropes, which hold 5-9 standard falls, are designated as standard fall ropes, those with more than 9 falls are designated multifall ropes.The number of falls is a direct measurement of a rope’s safety reserve. No new rope can break from an impact load, assuming good conditions and good rope management. But the efficiency of a rope decreases: aging and wear reduce its strength. Moisture and particularly frost can reduce it by about one or two standard falls.

Impact Force

The impact force is the maximum force which affects the load in a standard fall, when the rope absorbs the fall energy by its elongation. It is the measurement for the «hardness» of the fall. Ropes with higher impact force, when holding the fall, produce a stronger «jolt» in the falling body and on the safety system. In standard tests the impact force for single and twin ropes may not exceed 1200 daN and for half ropes ‹ 800 daN (approx. 800 kp). The practical relevance of the impact force is relatively small because it is measured with the standard static fall test, i.e.: the fall rope is completely fixed. In practice, however, a fall is almost always caught dynamically. Belay devices (Munter, figure eight, ATC, etc.) have a certain rope path, and their attachment to a central point, or on the harness, brings a dynamic effect. Through dynamic belaying a large part of the fall’s energy is dissipated and so the impact force is reduced. Measurements by Mammut of typical sport climbing falls show, that with dynamic belaying the difference in impact force between two different ropes is barely discernable. It’s therefore important to provide a truly dynamic belay.

Working Elongation

Working elongation indicates the elasticity of a rope with a static load. A piece of rope preloaded with 5 kg is loaded with 80 kg: elongation may not exceed 10% for single and twin ropes, and 12% for half ropes. Static working elongation mainly assesses comfort when top roping or hauling on big walls. In these cases, it’s annoying when energy is wasted through rope stretch, or if a difficult sequence has been climbed with a top rope and while resting this distance is lost. Elongation is more relevant to safety when falling (see below), because it determines whether the falling body will, for example, shock load a runner. Roughly speaking, a relationship exists between the two values for static and dynamic elongation.

First Fall Elongation

This parameter measures the elongation of the rope during the first standard fall. The maximum permissible elongation with this test is 40%. This dynamic fall elongation indicates the inertial properties of a rope better than the static value of working elongation. With greater elongation danger is increased, due to the fall impact on protection. All Mammut ropes already fulfill the requirements of the (not yet obligatory) EN standard. With values from 28-32% they fall well under the 40% permitted maximum.

Sheath Slippage

For this test a two meter long piece of rope is drawn five times through a test device – a metal drum, with a zigzag shaped, offset rope guide. The sheath and core are then rigorously tested by the milling action of the drum. The sheath may be displaced by a maximum of 20mm If the sheath and core slip during use, the rope can bulge and get lumps. If the ends are carelessly welded the sheath or core can slip out of alignment. With modern climbing ropes sheath slippage hardly ever occurs.


An over hand knot is tightened with a force of 10 daN and then loosened at 1 daN. Afterwards the inside diameter of the knot is allowed to be a maximum of 1.1 times as large as the rope diameter.Knotability is a reference point for the stiffness of a rope: with stiff ropes the knot cannot be as tightly tied, compared with a more supple rope, and the path through the belay device is possibly made more difficult. However, too much value shouldn’t be placed on this measurement, as the suppleness of a rope is also determined by care and the weather.

UIAA water absorption test

The UIAA Safety Commission has been setting safety standards for mountaineering equipment for many years. The new UIAA water absorption test for ropes is the first test to measure and compare the water-repellent properties of ropes.
In a first step, the specimen is scoured with three new M14 nuts. This scouring simulates the wear on the rope as occurs during rock and ice climbing; the quality of the simulation guarantees reliable results. The dry specimen is then weighed.
In a second step, the specimen is soaked in water at a rate of two liters per minute for a period of 15 minutes. After a brief period to drip off, the wet sample is weighed again.
Finally, the difference in weight between the dry and wet samples is calculated as a percentage. Only ropes that increase in weight by 5 % or less can use the UIAA Water Repellent safety label.

Static Ropes according to EN 1891

This European standard defines the requirements for static ropes (low stretch kernmantel ropes)Within the EN 1891 we differentiate between the following rope types:

Type A:
Ropes intended for use as safety ropes for working at heights (in combination with the relevant equipment) and as rescue ropes. Diameter 10 – 16 mm / Test weight dynamic test 100 kg.

Type B:
Ropes of smaller diameter and lower strength than Type A. Test weight dynamic test 80 kg. Usually used in combination with specially developed abseiling equipment according to EN 341.

Whoever entrusts their life to a Mammut rope has every right to expect the very highest standards of quality. We are fully committed to this requirement. All our ropes are produced in Switzerland. Every day, Mammut processes enough polyamide to go right around the world.

The 8.7 Serenity Dry – the thinnest and lightest single rope from Mammut

The age of ultra-lightweight, high-end sports climbing ropes began in 2006 with the launch of the 8.9 Serenity Dry: Back then Mammut developed the first single rope with a diameter of less than 9 mm. In summer 2013, Mammut will once again demonstrate what is possible in the field of ultra-light single ropes with the new 8.7 Serenity. The new 8.7 Serenity is the Mammut Pro Team climbers' secret weapon for tackling the toughest redpoint, flash and on-sight routes at the absolute limit. Its comparatively high sheath proportion means that the 8.7 Serenity Dry is the most durable rope in its class.

BiCo Sense

The BiCo Sense technology contains a thicker twine in the core of the rope; this thicker sheath twine comes to the surface at certain points on the rope. This way, the special sheath twine provides both visual and tangible markings for certain rope sections. This type of marking is used in the middle of the rope and 3 m before each end of the rope. The advantage is obvious: both belayer and climber are made aware of these sometimes critical rope sections, which allows, for example, accidents to be avoided during lowering.
