Our Verdict

Nylon has long been the go-to material for climbing slings, and the Sterling Nylon Slings carry on the tradition of nylon serving as a super functional and reliable material for your sling needs. 17mm nylon sewn with heavy duty bartacks offers the recreational climber the safety and ease of use that has become expected from a sewn nylon sling. While bulkier than a modern Dyneema sling, Sterlings nylon slings go for about half the price of their Dyneema brethren.

They are extremely user friendly, and can be used in a wide variety of applications. They are however, less durable than the Black Diamond Nylon Runner and so they will have a shorter lifespan. Also, if youre looking for something small and light, these slings just won't do. At 8mm wider than the Mammut Crocodile Sling and far less durable, these nylon slings should be considered only if youre on a strict budget. You wont be shelling out the big bucks for these, but expect to replace them more frequently than another nylon or Dyneema sling.

Our Analysis and Test Results


Sterling Nylon Slings offer the recreational trad climber a really affordable option for fleshing out their rack with the slings they need. With a standard strength of 22Kn you can rest assured that these slings are plenty safe when used properly. Aside from being far more affordable than Dyneema slings, nylon slings offer several advantages. The melting temperature of Nylon is higher than Dyneema, making this material more suited for doubling as a rappel back-up or a friction knot for emergency ascending.


Nylon-sewn climbing slings have more bulk and weight than Dyneema ones. Speed ascents, long approaches, or a desire to have the slimmest rack are all reasons to choose Dyneema over nylon. Sterling's nylon sling experienced far more fraying than its nylon competitors during our durability testing, meaning that you'll be replacing these guys far more often than a hardier sling.
