Say hello to our simple polyester webbing - JASP (Just a simple polyester). This plain weave webbing has nice characteristics for longlines and highline backups and can serve as a very low cost entry line in combination with our JYBN webbing.

55 g/m, 25 kN, and a decent stretch profile gives this webbing an excellent value for backup lines and longlines in the park.

Made in the US.

Sewn Ends For Easy Rigging

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

Every one of the fixed length options for JASP come with our Simple Sewn Loops on 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.

We use a high strength 138-lb bonded polyester thread with a minimum of 300 stitches in each sewn loop in order to provide as much strength and longevity as possible. With our high quality tooling and professional grade sewing machine, we are able to achieve very high consistency with our sewn loops, providing a strong and reliable anchor point on all of our webbings.

JASP 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. The color of this sleeving material will vary.

Please Note

All fixed lengths (50m, 60m, 85m, 100m, and 120m) come with sewn loops on both ends. Any custom lengths do not include sewn loops, they must be added to your order separately.
