Kernmantle rope (from German kern 'core' and mantel 'sheath') is rope constructed with its interior core protected by a woven exterior sheath designed to optimize strength, durability, and flexibility. The core fibers provide the tensile strength of the rope, while the sheath protects the core from abrasion during use. This is the only ...
Greater elasticity allows a dynamic rope to more slowly absorb the energy of a sudden load, such from arresting a climber's fall, by reducing the peak force on the rope and thus the probability of the rope's catastrophic failure. A kernmantle rope is the most common type of dynamic rope now used.

Although ropes made of natural fibres such as hemp and flax were used in the early days of alpinism, [1] modern climbing uses kernmantle ropes made of a core of nylon or other synthetic material and intertwined in a special way, surrounded by a separate sheath woven over it. The main strength of the rope is in the core, and the sheath of the ...
Some climbers will use a single full-thickness climbing rope with a diameter of approximately 9 to 11 mm (0.35 to 0.43 in), and some will use double ropes, or "half-ropes", to reduce rope drag (e.g. one rope is clipped into any given anchor or protection point), which have a reduced thickness of approximately 8 to 9 mm (0.31 to 0.35 in) to ...
Rope rescue is a subset of technical rescue that involves the use of rope, be it steel or cable rope, or more commonly used nylon, polyester, or other type of rope. Kernmantle (kern = core and mantle = sheath) rope as it is called, is available in various types: dynamic (stretches to absorb the shock of a falling lead climber or rescue ...
