Why We Like The Crag Dry Duodess Rope

Among Mammut's arsenal of Crag climbing ropes, the Crag Dry Duodess Rope stands out to us as a high-performance all-arounder for rock, ice, and every route in between. Mammut's Dry treatment excels UIAA's standards for abrasion-resistance as well as water-resistance, so this rope thrives in both desert and alpine environments. The skinny 9.5mm diameter delicately balances between strength and lightness, making the rope suitable for both single- and multi-pitch routes.

Here's what customers have to say

The rope is versatile and durable, with a smooth handling that works well with various belay devices. The bi-pattern design makes it easy to find the middle, and the dry treatment helps the rope stay dry and resist dirt buildup. Some users noted the rope can get kinky or twisted, but overall it is considered an excellent all-around rope suitable for a variety of climbing applications.

Great rope with durability and functionality. Looks great and I love the dual pattern.

I love the product but nothing is perfect so a 5 star is really hard to offer up.

Excellent for indoor and outdoor climbing

I've been using this rope for indoor and outdoor climbing for about sixth months, and I love it. It handles well, feeds nicely, and has withstood some whips with grace. I have nothing bad to say about it.

This rope lasted me through many trips. Single Pitch cragging to short and long Multipitch routes. It saw many whips and didn't need the ends to be cut until year 3. Very impressed. Just make sure you wash it to keep it performing well longer

You cannot go wrong with Mammut ropes. They are reliable, easy to flake (well, as easy as that can be), and smooth through the belay device. This is a great go-to rope, treated for some of our damper crags and surprise rain. Evident quality boosts confidence while high on the route. As I have written in past Mammut reviews, I am never afraid to put loved ones up on their ropes. Happy climbing, y’all!

My Go-To Rope

I’ve used this rope for two years now for both sport and trad climbing, as well as top roping. Not only do I appreciate the dry-treatment and its ability to keep the rope dry if a surprise shower comes, but it also increases the durability of the rope which I can definitely tell the difference in. Though the dry treatment has faded with various washings, I was able to use the rope for ice climbing before that and it worked very well in those conditions. Overall, I would highly recommend this rope to other climbers. I have a 70m version of it, and it’s been great across the country to access different climbs.

Simply the Best

If I were to own only one rope, this would be it. The balance of durability, weight, and elasticity make it the rope I reach for the most when I am headed to the crag. It also feeds well through a grigri and atc style devices. I've used other ropes that are more supple or lighter, but are less durable or stretch too much. I use this rope for single pitch and multi pitch trad mostly, and sometimes for toprope and sport. This rope balances them all nicely.

Great rope at a great price

Have been very happy with the Mammut 9.5 crag ropes. This dry rope gives me confidence to climb even when the weather starts looking rainy.
