Introducing the all new Spider Silk MK3, a new kind of HiTech webbing for long and highline use.

This webbing is unique in it's construction with a combination of Vectran and UHMWPE fibers mixed together for an optimized weave pattern that offers superior strength, stretch, and durability for the demanding project lines that it's intended for.

Not only does this webbing have a unique construction, it also comes in at 20mm in width! This helps with wind as it has 20% less surface area for the wind to capture on big lines. This will be especially noticeable for lines greater than 300m.

Updated Design information coming soon.

Sewn Ends For Easy Rigging

All fixed length options come with a free Simple Sewn Loop on one or both ends!

Every one of the fixed length options for Spider Silk MK3 come with a modified version of our Simple Sewn Loop on one or both ends of the line, free of charge! These simple sewn loops are sewn in a way that retains 85% or more of the strength of the webbing, which gives you a sewn and easy way to attach your line to your anchor. We've dimensioned the sewn loops such that many connectors can be attached to it at the same time, allowing backup anchors and multiple attachment points to be utilized.

Spider Silk MK3 Sewn Loop

The sewn ends have a sheath on the webbing in the sewn loop in order to protect a heavily abrasion-prone location on the line. This sheathing is made from a highly abrasion resistant cordura Nylon sleeving material, ensuring the wear point of the sewn loop is protected for hundreds of uses.

Please Note

Our 40m fixed length comes with a sewn loop one one end. All other lengths (60m, 90m, 120m, and 240m) come with sewn loops on both ends. Any custom lengths do not include sewn loops, they must be added to your order separately.
