Mammut Genesis Dry Climbing Rope - 8.5mm
MammutGenesis Dry Climbing Rope - 8.5mm

Lightweight safety for wandery and wet alpine routes.

Wandering alpine routes, ice climbs, or technical ascents call for a tough, water-resistant line like the Mammut Genesis Dry Climbing Rope. Certified to be used either as a half or twin rope, the Genesis weighs just 47 grams/meter, so it's not hard to pull up a peak, and it's treated with Mammut's Protect technology, which uses both Coated Sheath and Coated Core dry treatments to keep it from absorbing water, so it continues to handle smoothly and won't pick up extra weight.

Great half ropes

  • Familiarity: I've used it several times

Much like others have said these are great ropes. Lighter than carrying an extra single rope up with you for longer rappels and when planned accordingly really reduce rope drag when used as half ropes. They are easy to make knots in and have a great feel.

That being said, make sure you train yourself and your climbing partners ahead of time on how to half rope belay. It really is a much different technique than single rope belay, and it doesn't come intuitively despite being well trained and practiced on single rope belay. This is not something you want to do just before you expect to climb. Take the time to get it down solid and make sure everyone feels solid and comfortable with it.

On 4th Set of Mammut 8.5mm Doubles.

    I started with the 50m ropes, and now have 60s. Just re-lead Crying Time Again this week, but using a 60m lead cord. What a difference double-ropes make for reducing rope drag! Also, smaller/lighter partners appreciate the handling and ease of rappelling (i.e., usually not being heavy enough to easily rap down thicker ropes on lower angle rock). My Valley rope quiver includes a Mammut 9.5 duodess dry 60m cord, to accompany my 8.5s, which can always be split into trail ropes. I am convinced that dry treated ropes in general are worth the investment. For example, ever tried to dry out a "non-dry" rope after it has been soaked in a High Sierra thunderstorm? How long will it take? I say it will take days, ruining your trip, or worse.

    Mammut Genesis 8.5mm

    • Familiarity: I've used it several times

    After roughly 20 pitches, the Genesis 8.5mm's are holding up nicely. Sheath is durable and the ropes handle really well. While smaller, they seem to handle and feel like the Mammut Infinity which is a positive. Comparing the use of these 8.5's as twins/halves, my climbing partner and I found the 8.5's a little easier to manage on multi-pitch than using a single rope with some sort of tag line -- every climber has their preference though.

    I would definitely purchase these ropes again based on performance so far.

    Dunno about alpine, but great for rock

      maybe I'm into 'old school,' or I'm paranoid, or maybe just weird, but I really like using half ropes. Sure, it's more of a hassle to manage, and can lead to some serious clusters if you don't pay attention, but I like being able to do full length rappels, split up the rope nicely for carrying, and being able to use these as twins/doubles whenever the situation arises.

      These ropes in particular are great for rock - the most durable half ropes out there. this is definitely because they are also one of the fattest, but there is always a trade off. I'm happy mammut always adds a halfway mark - I don't always need to do a full length rappel.
