The SISKIN ECO DRY is the lightest single rope in the world. Thanks to our depth of production and the extraordinary manufacturing techniques at our site as well as our decades of experience, we were once again able to raise the bar for what is possible in terms of weight. With a diameter of 8.6 mm, the high-end rope weighs just 48 g per meter, making it the perfect rope for all vertical adventures, long climbs, and projects where every gram counts.
