Mammut Infinity 9.5mm Climbing Rope

I have only been using this rope for a few weeks, but in total that makes about 10 days of use so far. I was accustomed to using 10+mm workhorse ropes before this one, so it is to them that I'm making a comparison.

This rope is so very light, and it just glides. Pulling it up through draws to clip is so easy. While climbing with it, it feels effortless, and doesn't drag me down at all. Plus, it handles so well--no kinks, no twisting, no stiff tangles. The middle is marked with two black dye stripes by Mammut. My friend took a fall or two on it and said that the catches were fairly soft; I haven't taken any big falls on it so I can't speak as to that.

I use a tubular belay device, and even with that I'd say be a little careful the first time you lower someone, because the rope slips through faster than you'd expect.

I really, really love this rope, and I'm looking forward to it lasting a long time.

One note: I thought I was going to get an orange rope per the picture, but the one I received must be the updated color, which is an attractive blue ("Ocean" according to Mammut). It has the Mammut CoatingFinish (the Teflon coating).

I'm a rock climber, and have mostly used this rope for sport climbing (as well as a few trad/ multipitch routes). This rope is a perfect all-arounder. It's thin, but not TOO thin. So it's light, but isn't difficult to belay with, and doesn't wear out quickly. A major perk of this rope is that it stays supple with age. I've had many Infinity 9.5 ropes, and they've never, ever gotten any weird thick or thin spots, or worn strangely. Obviously, they do wear out eventually - but in a very predictable, visible way. Everyone who belays with it comments about how nice it feels...

Great rope for multipitch trad routes. This rope is simply beautiful. I appreciate the dry treatment on each of the core strands as well as the sheath. This apparently creates less friction inside the rope, so it can be engineered lighter/stronger.

Mainly it just performs better than any of my other ropes. Of course for this price it wont see top rope sessions or multi fall sport routes. For that I go with Bluewater Eliminators.

Out of the package climbable due to Mammut's lap coil, unlike Petzl's that seem to start twisty.

At 9.5 mm, this rope is thin enough to be light (and not cause much rope drag on long routes). But it's not SO thin that it wears out quickly, or is sketchy to belay with. This rope is extremely well made; I've had many of these, and they've never, ever worn out strangely. They always stay supple to the end, and have never gotten thick, clumpy, or weird in any way. Definitely a great, classic workhorse. People always comment about how nice it is to belay with.

This rope has a great hand right out of the wrapper. Lives up to it's impact force rating well, and catches everything beautifully from tiny slips to rad whippers. Tends to fray a little early, but heavy use on rough granite can do that to any rope. Dry treatment is still beading water, even after a almost a year of considerable use. Don't be deterred by the price, this rope is worth every penny. Plus, the orange is angry fierce.

I generally prefer Mammut ropes and this is my favorite. Handles well, lightweight for the approach. Does not kink on me which is huge. I've had ropes that drove me crazy with the kinking. I'm finding that sport routes seem to be getting longer and it's necessary to have a 70m, so with the extra length, a skinnier, lighter rope is easier on the approach and on clipping the chains, i.e. less drag.

I did a lot of research before buying, and this rope is always very highly rated. So far, I'm very happy. Although the sheath is a little rough and can rope burn sensitive hands easily, it is undoubtedly everything I was looking for - durable, light, stiff enough to clip well but supple enough to handle nicely. Doesn't knot easily, and stays cleaner and dryer than most ropes. Highly recommended.

I keep choosing this rope because it is as light as other 9mm ropes, but the sheath holds up like a 10mm. I would recommend this rope to anyone climbing trad or sport. Great handling characteristics make this rope friendly for its entire life. Definitely one of the best ropes on the market.

Fantastic on it's first climb outdoors, easy to handle, great through the belay device. Nice feel. Everyone asked how thick this rope is, 9.5. Didn't need a thick rope to do the job that this one was handling.

Use this rope a lot and it's well worth the cash. Got the 70m and it's lived up to mammut's reputation.
