As our recent trip to Chamonix involved a diverse range of climbing, my friends and I had to bring a number of ropes to suit all the different types of routes we planned to tackle. I brought along the Mammut 9.5 Infinity climbing rope that we would use for crag climbing as well as paired together with a similar single rope for use on some multi-pitch rock climbs.
My Mammut 9.5 Infinity climbing rope is 70 meters long, perfect for the sport climbing crags around Chamonix. As most routes are 35 meters or less, you don't have to worry about running out of rope when being lowered. A middle marker helps you decide when it will be safe to lower the lead climber. The 9.5mm diameter is burly enough against the rock and strong enough to take quite a few falls (UIAA-falls 1 strand 80kg rated 8-9).
On some of the long, multi-pitch rock climbs in the Mont Blanc area, using a single rope is sufficient, as you can walk off or may need only to complete a couple of short rappels in order to get down. More often than not, we felt more comfortable climbing with a set of half ropes to enable full-length rappels if needed. When there were three of us multi-pitch rock climbing, however, we used two single ropes, including the 9.5 Infinity, in place of the half ropes simply for better resistance against sharp rock.
Part of the COATINGfinish line, the 9.5 Infinity comes with a PTFE or Teflon coating. The climbing rope is incredibly smooth to handle, runs almost friction-free over rock, and absorb substantially less dirt and water. The rope handled well through a Petzl Reverso 3 device for both belaying and rappelling. The Mammut climbing ropes come lap coiled, supposedly enabling you to use them tangle free right out of the packaging.
Mammut created a great infographic that helps you figure out exactly which rope you should buy depending on your intended climbing use. Sometimes, with all the different climbing ropes on offer from one company, it can be hard to know exactly which one to get unless you receive a recommendation.
Bottom Line: If you are a weight watching sport climber or plan on climbing short rappel (up to 40m) or rappel-free multi-pitch rock routes, check out the Mammut 9.5 Infinity.
The Mammut 9.5 Infinity climbing rope retails for $240 (60m), $260 (70m), or $290 (80m) and is available now.
