At its core Mammut is a rope company, so it is no surprise that the brand continues to produce lighter, better performing, and more durable ropes season after season. The Infinity Protect 9. 5mm Climbing Rope strikes a balance between weight and durability. This light line has a weight of just 58 gm, so it won't weigh you down on multi pitch routes and will perform well when on sighting sport climbs. Mammut's Coated Sheath technology increases the rope's abrasion resistance and lifespan under heavier use.
