Black Diamond vs Mammut

The Black Diamond Mammut slings are identical on paper. The differences are as follows:

- The stitching on the Mammut is shorter, and the ends spliced in such a way as not to catch on things
- The Black Diamond slings seem less prone to fuzzing and abrasion
- The Mammut is more flexible, knottable, and handles better.
- The Black Diamond seems to slide more smoothly through carabiners in self-equalizing rigs.
- They're both the same width, despite being "8mm" and "10mm" on the spec sheets.

It doesn't make much difference in the end. Both are far far lighter and more compact than nylon, and less prone to twists and tangles than cord.

I use Mammut for my draws and Black Diamond for anchor rigging just so I can tell them apart at a glance.

I love this

My primary use of this item is as a personal backup, while rigging a Challenge course. It just a nice to feel the extra protection while rigging a course solo.
Love it, I am going to require anyone rigging the course to use it. The weight is very light, and why not have it.
I will not enter a course with out one.

Go to item

I climb about once a week and have not run out of uses for these things yet. I make chest harnesses for my smaller kids, extend anchors, build toprope anchors, etc.
Its just one of those things you need and it works as it should.

Great piece of gear

I've been trading a while, and these are great to bring up a wall. There's no stress about weight what-so-ever. The Koreans I climb with are certainly blown away by them! The slings do, of course being so thin, tend to get "twisty".

Dynex slings good, MGear staff bad.

The BD Dynex slings themselves are fine, look equally good in quality as the ten uniformly black-n-white WC 10mm slings they are replacing. Good slngs, but might want to get them somewhere else.

The stitching where the runner meets could be covered or less snaggy. But they are great runners. I only got these over the mammuts because of cost.

I used it to make an Alpine Quickdraw. I bought a few of these slings last year and they have held up well.

Slings that you could hang your car from

The only negative comment is that they look sooooooo thin. The stitching is beautiful and for thin slings they hold up pretty well

Good, but Mammut slings are better

I like the slings, but are not really better than any other sling I've had. The Mammut slings of the same size are better because of the way the Mammut label surrounds the sling's attachment point, reducing the chance of the sling snagging. Overall though, they work for what they're intended for.
