Crag Dry Duodess Rope - 9.5mm
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.

Best rope
After 50+ pitches this rope still looks relatively new and handles well. No soft spots or fraying even through some abuse

Workhorse of a rope!
This is a super good rope that I’ve used for cragging and multipitch tradlines in the Sierras. It really shines with rope roping and big wall climbing.

My favorite sport climbing rope
Nice and durable 9.5mm climbing rope. The pink finish really stands out. The dry finish was nice while it lasted (gone after two seasons). The rope has been very durable and has seen many whips/TR use. The only downside is that the middle mark wears out quickly.

Favorite rope!
Love the orange bicolor for easy rappels. Handles well, not too soft or too stiff. Dry treatment is great for extending the life of the rope. Doesn't kink up easily like some others on the market. Good diameter to weight ratio for carrying to the crag. I will keep buying this rope. Just wish it came in other bicolor patterns besides orange!

Great rope
This rope is perfect for the price point. I use it for all my trad climbing single and multipitch and I won’t use another rope unless I’m alpine climbing and that’s a Mammut rope too.

Good sport climbing rope
Took this rope to hundreds of cragging days for single pitch sport, and occasionally took it on multipitch climbs. It started getting fuzzy after a month or two, but the core held up well until the second year. I was climbing on it almost every weekend and put it through the ringer. Held up great to sandstone. It started getting pretty worn down after some sharp limestone multipitching. For how often I was using it, it lasted well.

Mammut 9.5 Crag Dry Rope (80m) – Premium Rope for Serious Outdoor Climbers
I’ve been using the Mammut 9.5 Crag Dry Rope (in the 80m length) for a ton of outdoor climbing this season, and it’s easily one of the best ropes I’ve used. Super high quality, handles smoothly right out of the package, and feels confidence-inspiring whether I’m leading or rappelling. The dry treatment is great for alpine or variable weather days—it sheds moisture well and doesn’t pick up dirt as quickly as untreated ropes. I’ve put it through everything from dusty crags to snow-covered approaches, and it’s held up like a champ. One of my favorite features is the pattern change at the halfway point—huge help when you’re setting up rappels or checking if you’ve got enough rope for a lower. It’s a small detail that makes a big difference, especially on longer routes. The 80m length has been perfect for longer single-pitch sport climbs and multi-pitch routes where a standard 60 or 70 just wouldn’t cut it. Being able to link pitches or rap with fewer anchors saves a ton of time and hassle. If you’re doing a lot of outdoor climbing and want a top-tier rope that’s both durable and versatile, I’d absolutely recommend the Crag Dry. Mammut nailed it with this one.

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.

For the number of UIAA Falls it indicates "7-Jun." What is 7-Jun?

How old would this rope be, from being made if I bought it?
