9.5 Alpine Core Protect Dry Rope 80m

Dynamic, easy-to-handle, and significantly more cut-resistant, our new Core Protect Dry Rope is built for safer climbing. The increased cut resistance comes from an extra layer of protection between the outer sheath and core, made from aramid – a military grade fiber renowned for its resistance.

As a static material, aramid lacks the dynamic properties needed for a climbing rope – we combat this by braiding the aramid sheath with extra length. Under tension, the aramid can protect the core of the rope by unfolding to its full length, without being subject to the maximum force during the fall.

While the quality of today’s climbing ropes is very high, accidents still occur when sharp edges are involved. Usually, these are found in alpine routes, crack climbing along granite lines, and sports climbing due to sharp carabiners.

Studies from the German Alpine Club found that broken ropes were the cause of 53 accidents between 1965-2015 – 35 by sharp edges. Accidents have also risen in recent years due to a trend towards thinner ropes. Our Core Protect Dry Rope increases the safety and cut-resistance compared to normal, dynamic climbing ropes.

Firstly, we created a realistic fall scenario, which saw a climber with 80kg follow a multi-pitch route before falling in a traverse over a granite edge, with 90 cm of slack in the system. We found that the additional aramid sheath not only protects the core of your rope when encountering a sharp edge – it does so even better than your normal, dynamic climbing rope.

Next, our internal team tested it. Both our rope developers and our climbing team spent days at the Swiss crag to test and optimize the Core Protect Rope – not only as technical experts, but as passionate climbers who understand what the discipline requires.

Finally, we got Mammut athletes Jonas Schild and Katherine Choong to test the ropes outdoors, as well as several mountain guides in the Swiss Alps and around the world.

This vigorous testing, alongside the patented technology is how we've made sure that the Core Protect Dry Rope is ready for your next adventure in the mountains.
