Our Verdict

At 13mm wide the Metolius Monster Sling is lighter weight than a nylon sling, but not as lightweight as a skinny sling such as the Mammut Crocodile sling. These slings are a fine middle of the road option for the recreational climber that won't be putting their slings through heavy use and abuse. We also found it strange that Metolius would cut their slings down by 2 inches from all of their competitors. They're also spendy. Bottom line is, if you are looking for the highest quality Dyneema sling; check out Trango Ultratape, or the Sterling Dyneema Sling. If weight is a huge priority to you, the Mammut Crocodile Sling is going to be your best bet.

Our Analysis and Test Results


Metolius Monster Open Loop slings are made with a 36% Dyneema 64% nylon blend and are a fairly decent option for the climber seeking a medium width, Dyneema sling.

At 13mm wide it runs about the middle of the road as far as Dyneema slings go, though it is still a step down in weight from a traditional, bulky nylon sling. We found that the slings' width, thickness, and tubular design made it one of the easier slings we tested to untie a weighted knot. We also enjoyed the smooth handling and flexibility of the sling.


Because the material is Dyneema, the price difference is a jump from traditional nylon slings. Metolius' Monster 22" Open Loop slings run at about $7, making them one of the most expensive shoulder length slings we tested. These slings also run about 2 inches shorter than standard length slings…weird. In our durability test Metolius' slings performed in the lower rung. We observed significantly more fraying when compared to the other Dyneema slings.

Best Applications

Everyday traditional climbing applications: setting anchors, extending gear placements, slinging horns.
