Not all light ropes wear out quickly.

If you want a light line but don't want to sacrifice durability, get yourself the 9.5mm Mammut Infinity. This rope weighs a scant 58g/m, making it a perfect pick for alpine routes and high-end sport climbs where every ounce really makes a difference. Unlike other ropes, the Infinity uses Mammut's Teflon coating process which covers each fiber individually to reduce internal friction and increase the line's life span.

The part at the end where the ropes are tested for quality assurance is pretty rad!

I need a rope for glacier travel that I...

Posted on

I need a rope for glacier travel that I can also use rock climbing if I ever decide to get into it. Is this the rope for me?

Best Answer Responded on

Possibly. It really depends on a few variables. How many people do you plan to travel with on the glacier? Teams generally consist of 3 but, sometimes you go with 2 or 4. With 2 people you would have the most rope between your partner and yourself and 60 m would leave you with a lot extra. Generally I would use a 50 m rope for this as its enough rope between climbers plus you have more than enough to perform the rescue if necessary. Could you get away with 60 m? Sure, it just might be unnecessarily heavy, which matters if your going on a big trip or trying to move fast. If you have a 4 person team the 60 m is a necessity to ensure the lead and caboose have enough rope to perform a rescue.

Personally I would get 2 ropes, something like a Beal 8.1 it comes in 50 m and strong enough to hold a fall in most glacier environments. Realize the rating is half that of the Mammut, so maybe I would be worried taking a huge whipper on this. I own the Mammut Infinity and its great for climbing as its really durable, I also use it ice climbing as it's rated for single rope use. If you used the Infinity for glacier travel its too heavy, if you used something like the Beal Ice line its not durable enough for extended use and is kinda scary if your sport climbing and possibly going to take a big fall.

I just wanted to let everyone know that the Ocean color variant is not a bicolor rope like the other one we offered but are now sold out of. Thanks.

Light weight but still durable. Amazing!

  • Familiarity: I've used it once or twice and have initial impressions

I wanted a rope which I could use for both in rock climbing and mountaineering. So I wanted my rope to have dry treamtement/s on it and light weight as well as being tough. This rope was perfect for what I was needing for and I will definitely rate 5 out of 5!

Hi! Thanks for your short review. What do you think about weight? Is it really 58 gr. / m or is it more?

Posted on

Is this rope (70 meter/259.15$) is bipattern or has a mark on the middle by default or do we have to ask for it?

Responded on

To the best of my knowledge, it has a mark on the middlepoint automatically, from the manufacturer.

Best Answer Responded on

There is no mark with the bi-pattern. Just the bi-pattern to designate the middle point. I added a mark just so I could catch it easier in the dark of if I am moving the rope through my hand/ anchors fast.

Great Rope

  • Gender: Male
  • Familiarity: I've put it through the wringer

This was the first rope I have ever purchased for personal use. My friends who taught me how to climb have fatter ropes so I went with something skinnier that we could use on longer approaches or on ice. The rope has a great feel to it, supple, easy to knot and coil. Definitely feel secure, taken a few falls and the stretch is perfect, soft catches. I bought it this Fall and used it through various Sport/top rope/ and Ice Climbing, still looks really good. There is a little fraying for sure but, overall the rope looks in great condition. Definitely plan to get a few more years of use out of it.

Excellent Skinny Rope

  • Familiarity: I've used it several times

I bought the 70m bi-pattern version to take outside. So far this rope hasn't disappointed. I was amazed at how much easier it was to work with a quality rope versus the inexpensive rope I bought first.

The Good:
--Excellent feel and feeding through all my belay devices; especially nice giving slack on lead belay from a Grigri.
--Skinny enough that it's light for long approachs/backcountry work, fat enough to still catch perfectly in a Grigri 2.
--Not kinky at all.
--Nice soft catch, and not any more extension than my cheap, 10.0mm gym rope
--Bi-pattern makes watching for center easy on long lowers and rappels.

The Bad:
--More expensive than some other offerings.

I winced a bit when I paid for this rope, but I'm glad I did. When my current gym rope dies, I may take that as an excuse to buy another one of these!

Hey, the description says it's a bi-pattern but the pictures appear otherwise. I want to confirm that its a bi-pattern rope.

Responded on

Hello, I believe its an older photo, the photo "center" shows accurately what the rope pattern looks like. You can easily identify the different ends at the center.
Hope this helps

The Ocean variant is a single color while the Yellow Duodess is indeed a bi-pattern. Duodess is the Mammut designation for bi-patterned weaves.

Smooth like silk

  • Familiarity: I've used it several times

I bought the 70m bi-pattern, and I love it. It's definitely worth the extra $ for the bi-pattern, as it makes rappels so much faster and easier, not having to search/coil for the mid-point every time. As far as performance, this rope is a dream. For both the climber and the belayer, it runs smooth, is light and easy to handle, and doesn't get kinked. I use it for sport-cragging and multi-pitch trad routes, and it performs ideally on both. Not the cheapest rope I've bought, but worth it.

Hells yeah

  • Familiarity: I've put it through the wringer

I think this rope is the best handling dry rope I've ever used. It has been super durable for me on Little Cottonwood granite and I'm not afraid to take it when I know some folks will be hang dogging or top roping routes with me. Highly recommend after several months of 3-4x per week use.

Glides like a dream

  • Familiarity: I've used it several times

This rope is so supple! I have the 70m 9.5 Yellow Duodess. I took it climbing in Eldorado Canyon and Lumpy Ridge and it glides like a dream. It's thin and sleek enough to feed through an autoblock without wearing your arms out, but still breaks very securely in the Black Diamond ATC Guide. With the narrow diameter the weight savings are sweet, and the bipattern made it clear to my climbing partner that we needed to belay from the top on a single pitch route.
