Here's what others have to say...



  • Familiarity:I've put it through the wringer

Whether you're building alpine draws, racking gear or anchoring in, Dyneema Sewn Runners have so many uses on the rock. I picked up a couple 24" slings to add to the wall-o-runners in my gear room (read house), which I generally use for racking cams over the shoulder.


The best

  • Familiarity:I've put it through the wringer

They're awesome , hold up to my falls and I fall a lot. I buy a lot of these because sometimes I break my leg and out of anger I kick 7 of them down 2,000 vert feet into drigs Idaho instead of slinging them over my shoulder like a reasonable person would. Great for alpine and trad climbing.


Good stuff

  • Familiarity:I've used it several times

I use these for v threads when ice climbing mostly. they are just small enough that it is quite easy to pull them through. quite happy with the quality so far.

How is the length of sewn runners measured? Is...

How is the length of sewn runners measured?

Is it the full diameter or is it half the diameter (as when the loop is closed and pulled straight)?

Hey Ed B.,

Thanks for your question.

The lengths listed in the drop down menu are the drop lengths. The overall length of the runner and not the full circumference measurement.

I hope this helps.


Trad Draw Material

  • Familiarity:I've put it through the wringer

I used these to make myself some trad draws. They're really inexpensive and have held up really well so far. Definitely recommended!


Trust 'em!

  • Familiarity:I've put it through the wringer

These are my go-to for fun trad adventures, and would work fine if you need a long draw for sport stuff too.


Good Runners!

  • Familiarity:I've used it several times

Nice and light, good color, durable. They are rated at 22kN, which happens to be the same as the other narrower runners.... so future purchases will be of the narrower variety to save on bulk.

Adjustable Quickdraw

Adjustable Quickdraw

1 Sterling 60cm runner + 1 Mammut wiregate + 1 Mammut Straight Gate = 1 Superlight Adjustable alpine quickdraw with an overall length of 33cm!!


I heart Sterling Dyneema Sewn Runners

  • Familiarity:I've put it through the wringer

I picked up a couple of the Sterling Dyneema Sewn Runners a few months ago and have been using them religiously ever since. They are a huge upgrade from my old nylon slings, they are way less bulky and significantly lighter. I am officially sold on dyneema after using these.


Weights measured

    10in.: 13.9g = .49oz. ; 24in.: 28.8g = 1.01oz. ; 48in.: 55.7g = 1.96oz.

    • Familiarity:I've put it through the wringer

    Nothing special but nothing bad. I got 24 inch, wish I would have gotten longer ones.


    Good for making alpine draws

      Sterling Dyneema runners is a little bit softer then Blue Water Titan Slings.

      Sterling Dyneema 24" Sewn Runners is the #1 alpine draw slings in my book.

      P.S. Also like orange color.


      Not too different from other Dyneema Runners

        I have the BD, Petzl, Mammut, and these Sterling Rope Dyneema Runners and they all have basically same KN rating. Some are a little thicker than others, and some are a little wider than others but they are basically all the same. When it comes time to buy new runners I go for the lowest priced ones ;)


        Nice mid width

          These feel more durable than the really skinny dyneema on the market. They have a nice hand and should last a few seasons.


          Decent Dyneema

            I don't like these as much as the BD or Mammut runners, but they're pretty good. They just don't seem as beefy as the other runners in the same size.



              Does the job just fine for me. I would totally recommend them.
