HighTech polyester webbing with low packing mass and weight. Which is perfect for alpine products as main or backup line. The low weight also makes it easy to control for longline tricks like bouncing or surfing.

halfMarathon – 20mm polyester webbing for king lines

HalfMarathon likely offers the best weight-to-strength ratio among 20mm wide polyester webbing available on the market, and it feels amazing, whether you’re walking or surfing on it!

It retains all the technical qualities of the regular Marathon while being 25% lighter. Weighing in at just 48.5 grams per meter, this 20mm webbing is one of the lightest polyester options available. Additionally, all pieces, regardless of their length, include sewn loops on both ends.

The minimum breaking strength of 28kN allows you to slackline comfortably without compromising on safety. To ensure a smaller pack size, the webbing has a width of 20mm. Great for breaking records, longline tricks and alpine projects.

halfMarathon is produced with a 3-layer construction which keeps the inner fibers at a higher tension than the outer fibers. This construction makes the line more abrasion-resistant and ensures that the line is still soft on your feet, even highly tensioned. The advanced manufacturing process gives this 20mm webbing a superb breaking strength to weight ratio of 28kN and 48.5 grams per meter. Furthermore, the 3-layer construction and high-performance fibers allow the edges to be perfectly round. The different colors on each side will help you to detect twists during rigging. Every order of halfMarathon comes with a pair of spacers for the SeaHorse Weblock. For any other linelockers, spacers would need to be manually produced/cut.

NOTE: The Neon Green/Pink color option with endloops is available for presale only. Shipments are scheduled to start in the first half of June 2024.
