Wandering alpine routes, ice climbs, or technical ascents call for a tough, water-resistant line like the Mammut Genesis Dry Climbing Rope. Certified to be used either as a half or twin rope, the Genesis weighs just 47 grams/meter, so it's not hard to pull up a peak, and it's treated with Mammut's Protect technology, which uses both Coated Sheath and Coated Core dry treatments to keep it from absorbing water, so it continues to handle smoothly and won't pick up extra weight.
