Featuring innovative Dry technology, this ultra-durable, triple-certified climbing rope is both dirt- and water-repellent. Mammut also reduced the environmental impact of our production process by reprocessing fabric scraps into a new sheath. Another nice feature is that every rope has a unique pattern because of this recycling process. Unique and environmentally friendly in the high quality you expect from Mammut. For ropes with a diameter of 9 mm and less Mammut only uses the highest quality yarns, and it shows: they're lightweight, offer excellent handling, and superior performance.
