I really like these slings for their lightweight and sleek design. Also they seem to absorb a lot less water than my nylon slings which makes them a great choice for ice climbing, alpine climbing, mountaineering and ski-mountaineering. I have found myself leaving my nylon slings at home even when just going to crag.

How do I love you Sling...let me count the ways.
You've always been there for me over the days
You catch my falls
And extend so well
When I don't have big balls
I use you to bail.
Some call you a runner
I call you a friend
I use you to cut rope drag
When I climb round a bend.
You're the perfect combination
Of Light and Strong
You improve my belay station
With you I can't go wrong!
I love you sling...
Marry me
We will sing
With Joy and Glee!
Over the shoulder
or as a quickdraw
Youre the best sling
That I ever saw.

These are the perfect compromise from the super skinny mammut slings of a few years ago, and thicker nylon ones. This compromise offers much improved durability over the skinnier slings, as they incorporate more nylon into the mix. They will still wear out faster than pure nylon slings, but hey gear like this should be replaced more often than not if you are out there climbing tons!

I feel obligated to correct "kowles_52455342" on his statement that "Dynex is Dangerous". It's just not true. I've been climbing for 16 years, competing for 4 and teaching for 2, and I can guarantee you without a shadow of a doubt that Dynex imparts 0.0% more force on a system than nylon. Static is static. No stretch at all on either system. That said, a static fall as short as 4 feet (theoretically) can kill you, so make sure you keep the slack out of the system if you're clipped into an anchor with slings, but the idea that Dynex will somehow make this worse or that nylon slings will take some of the force of a fall is just plain bullsh*t. It's a Luddite bias against newer and better gear that I have been trying to argue against for years, and I want it out on the table for what it is. These are fantastic slings, light and strong, and would be a complement to any rack for any discipline.

These are great--insanely light! I love'em. Can't say anything bad about them. Phenomenal!

Awesome runner! hands down the best on the market

Best one i have ever onwed

I love little dental floss slings, but I find the durability of the 8mm Mammuts leaves something to be desired (though those are very nice as well, just need to be replaced more often). I think that Black Diamond has found the perfect compromise between size and durability with their 10mm slings. These really are excellent slings, and I'm slowly replacing all my other slings with these, other than the two nylon slings I use for carrying gear (these are a bit skinny and uncomfortable for shoulder carry of a heavy rack, which is probably the only use they aren't ideal for).

I have a bunch of old nylon runners and some tied nylon loops, so when I snagged one of these, I was so impressed by how thin and light it was. I haven't died yet, so I guess they do a pretty good job as well.

super light, super strong, and nice and thin. I really light this runner.

These slings are great. Two will hold my weight with no problem and they don't stretch with tension. I wish they made some at about the 90cm length.

i paired two of these runners with two BD vaporlocks and absolutely love them for cleaning routes and setting up personal protection at the chains. it's always good to have a few extra runners around anyway, so do yourself a favor and pick up a few.

maybe a bit on the pricey side but they make up for it with versatility. strong and thin enough that they can be doubled, tripled, or even quadrupled without becoming too cumbersome giving you lengths anywhere from 120cm down to 30cm. a great buy

More durable than the Mammut runners and almost as light. I have much more confidence in these than the Mammut product. And no complaints whatsoever. Easy to triple, light over the shoulder, great for ice and alpine, as well as cragging. BD did it right.

I bought a few of these a year ago and they seem to be holding up really well.

strong, lightweight...yep

I used to wonder how these could be that much better than nylon until I bought some. The weight/size benefits of dynex is definitely worth the extra $$. They are practically nonexistent on your rack until you need them...then they unravel into a super-versatile full-length runner.

These runners are almost too light. Weight to strength rating ratio is surprising.

Haven't used them yet, but they seem VERY strong and I have no doubt that I will feel comfortable using them. I don't anticipate any concern at all with their performance.

these are great runners...almost too light! i somehow lost one even though i thought it was slung over my shoulder. good thing i got them while backcountry was having their big sale. :)

they handle real well and make extending, tying, etc. quick and smooth. As slim as they are, definitely keeps your rack lighter and easier organized. Once loaded though, they are hard to untie which can be a pain. Going with 12mm would improve that.

I've used a pair exclusively to aid in cleaning sport routes for a while now and they work great. Strong, light (skinny, but not to skinny, and not scary) and they've lasted two seasons now. Slings like rope that support your weight should be replaced often (especially when they cost so little vs rope) but these outlasted my expectations. Give them a try!

Dynex rules! Strong, light weight and easy to handle. At this point, all of my sewn nylon runners have been upgraded to Dynex.

Dynex is strong, light, and easy to work with. Good stuff!

These runners are super strong and easy to work with. Some of the best runners i've ever used. BD got it right again.

very skinny which makes it great work with. It amazing going from the big wide dyneema to this skinny webbing. its weird at first, i mean you can talk numbers all day long of how strong it is, but after a while you see the value of having it. you won't be dissapointed.

Hey, just remember to keep the rope as part of your equation with these slings. Compared to Nylon, Dynex will impart a much higher force on an anchor and harness if you (for example) are tied in to the anchor with one of these and slip.
