Outdoor Gear Lab Gear Review rating 5/5

The name Infinity does a good job of indicating the outstanding level of durability that you can expect from this slim cord. But it is also the solid performance it offers in low weight, catch, and handling that make it such a well balanced rope and our Editors' Choice winner. There are many other ropes out there that might surpass the Infinity for one particular application, but none of them can match the consistent benefits across a range of disciplines. If you can only have one rope, you can't do any better than the Mammut Infinity.

This is another high quality rope from Mammut. It fits perfectly into the category of light and functional, not something you use merely for your sport climbing project, but one you can also trust for a long day climb. All things considered probably one of the best all around ropes on the market right now.

Blister Gear Review no rating given just a review

I was extremely impressed by its handling and performance in all non-specialty scenarios and, from a durability standpoint, it still looked very good after a whole season of climbing. The Infinity sets the bar for the “one-rope quiver” pretty high, and it’ll be exciting to see if this new, thinner generation can top it.

Upon my return I purchased a 60m Mammut Infinity 9.5mm . This rope has been awesome and quite durable. While it is marketed as 9.5 it feels fairly thick and definitely fuzzed up a bit over the years, so it doesn’t feed super fast in a Gri-Gri. Regardless, I enjoy the clipping action and even though we had to cut the ends off, making it only about 155 feet, I still like using it. So far this is my favorite rope and at some point I will likely get a new one of the 70 meter variety. It is light enough for a hard redpoint but still durable to last on day of projecting.

Climbing Gear Review rating A

Summary: Mammut’s Infinity strikes a balance between light weight, durability, and handling. Virtually kink-free right out of the factory coil, this cord clipped well, held up to extended working sessions, and fed smoothly through allbelay devices. Those with tender hands should opt for belay gloves, as a few testers found the sheath to be a bit coarse.
Pros: Lightweight. Durable.
Cons: Coarse sheath.
