halfMarathon – 20mm Webbing for king lines

Half-Marathon is the royal webbing for your king line! It as all the technical qualities of the regular Marathon while being 25% lighter. At a weight of 48.5 grams per meter, this 20mm webbing is one of the lightest polyester solutions on the market.

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 spacers for the SeaHorse linelocker. For any other linelockers, spacers would need to be manually produced/cut.
