The Skinny

Dyneema sewn slings have become hugely popular for their functionality as a lightweight, low bulk alternative to traditional nylon slings. Sterlings sewn Dyneema slings proved to be some of the most durable and easy to handle slings that we tested. While they arent the skinniest Dyneema slings on the market, at 12mm wide they are 5mm thinner than their nylon counterparts, making them a great option when you are looking to travel a little on the lighter side. Dyneema is, however, a bit more costly than standard nylon, so if weight isnt one of your top priorities, or youre on a budget, stick with the nylon.

While Sterlings Dyneema slings are slightly larger than some of the other Dyneema slings we tested, like the Petzl FinAnneau Sling, they proved to be much easier to untie and slightly more durable. However, when compared to super skinny, yet highly durable sling like the Mammut Crocodile Sling, Sterling Dyneema might not be the best option. If you want a somewhat lightweight, easy to tie and untie, smooth handling sling, this will do you just fine. But if you seek the super lightweight, look elsewhere.


Our Analysis and Test Results

Likes


The Sterling Dyneema Sling offers several advantages over traditional nylon slings. Dyneema is significantly stronger than nylon, allowing for slings with a much smaller width to maintain full strength. With a strength of 22Kn, Sterlings one-half inch Dyneema slings are just as strong as one-inch sewn nylon slings. While slightly larger than some other Dyneema slings, when compared to nylon the slimmer profile cuts down on bulk and ultimately on weight, making Dyneema a prime choice for the climber looking for a little lighter rack.

We found Sterlings Dyneema slings to be among the smoothest handling and most durable slings that we tested. They can quickly and easily be made into an alpine draw and we rarely had trouble with tangles. We also found that untying a weighted knot in the sling was pleasantly easy. In our durability test, we found sterling to be a top performer, assuaging those fears of a sling being easily sliced over a sharp edge.

Dislikes


As with all Dyneema slings, these slings have no dynamic properties. As such, it is not recommended that Dyneema slings be used to clip yourself into an anchor system. Dyneema also has a lower melting point than nylon, making it only suitable to use as a rappel backup or friction knot in a serious pinch. While the sling functioned fine when rigged as an auto-block in testing, the safety is compromised by the chance of a melted sling. If weight is a high priority, and you don't foresee any long, sketchy rappels in your future, Sterling Dyneema is an excellent choice.

Best Applications


Sterlings slings are an excellent option for the climber looking to bulk-down from nylon and is also looking for a more substantial sling than the ├╝ber-skinny Dyneema slings. Perfect for long traditional rock or alpine routes.
