Features HD Cover technologyPerform 3 conceptSupereverdry treatmentSize: 8.2mmNumber of Falls: 8Impact Force: 5.5kNWeight per metre: 43g Glossary HD Cover Technology:A technology through which each cover thread is individually controlled, as opposed to standard braiding where the threads are controlled by pairs. Although the thickness of the sheath remains the same, the rope surface is much smoother than with a standard braiding, the rope doesn't generate extra braking in belay systems and actions become more comfortable. The wear due to abrasion is also reduced and the ropes lifetime extended. Perform 3 Concept:Offers improved flexibility for increased comfort, improved energy absorption for increased safety, and weight reduction for increased performance. Supereverdry Treatment:Applied to all fibres in the core and the sheath, this treatment makes ropes lighter in humid conditions, quick drying, and less likely to stiffen in freezing conditions.
