Mammut Magic Sling 12.0 for Sale, Reviews, Deals and Guides

I was excited to add this piece of gear for building anchors, since everyone said it was ideal for slinging trees. It's quite stiff and difficult to rack, but that wasn't a problem since I was just going to use it to build top-rope anchors. I used it for one day, set it up and didn't fuss with it after that - only used it on the one climb, slung around a tree, only on top-rope, with just a few folks climbing that route throughout the day - nothing dramatic, no big falls. At the end of the day, though, the "magic sling" already had several spots where (minimal?) friction had rubbed the abrasion-resistant sheath away. One of the other reviewers called it a single-use product, but I was hoping to get more than one day's use out of it. I'm not even sure it held up much better than the regular Mammut slings I have. Might have just been a dud, but I was pretty disappointed compared to the usual quality from Mammut.

A single use product. Not entirely sure what mammut designed these for, probably could have looked at the information tag if I hadn’t immediately thrown that tag away. All I know is it perfectly fits a very singular niche that I am quite happy to have filled. I’ve found myself slinging some mildly to moderately sketchy things on alpine ascents and have always simply clipped the rope and continued upwards trying not to wonder what would happen if I were to fall on the thin dyneema ran tautly over a sharp granite horn. I purchased a double length “magic sling” (spectacular name by the way), more out of intrigue than intended use. However, I’m quite happy to say it sits on my rack for those outings where I plan on slinging the gnarliest thing I can find before running out thirty feet of icy slab. Still has only one conceivable use so, sorry Mammut, four stars for you.

These are super strong and stiff. I havent used them yet but I can tell just by holding them they are going to make my racking a mess I would probably return if they were more expensive

Firstly, I have zero doubt that this thing is bombproof and could handle anything you throw at it. However, this comes at a cost of massively added bulk and stiffness. I would never try to make alpine draws out of one of these due to the size and stiffness. I ordered one to use as a personal anchor sling for cleaning anchors, but it's way overbuilt even for that. It handles quite poorly and takes up extra space on my harness. The best use I can think of is if you need to extend a piece or build an anchor over a very sharp edge and want some extra confidence. However, in that scenario I would rather just use 2 regular slings in place of one of these beasts. Oh yeah - it would also be ideal for the Texas Rope Trick for bailing from a bolt hangar without losing gear (look it up). TLDR: Way overbuilt. Confidence inspiring, but bulky and handles poorly. May have niche applications, but I would avoid for most normal uses. For most applications just buy Mammut's 8mm Contact Slings instead.
