A wide range of equipment is used during rock climbing. The most popular types of climbing equipment are briefly described in this article. The article on protecting a climb describes equipment commonly used to protect a climber against the consequences of a fall. ''See also the Glossary of climbing terms for more equipment descriptions.'' Climbing ropes are typically of kernmantle construction, consisting of a core (kern) of long twisted fibres and an outer sheath (mantle) of woven coloured fibres. The core provides about 80% of the tensile strength, while the sheath is a durable layer that protects the core and gives the rope desirable handling characteristics. Ropes used for climbing can be divided into two classes: dynamic ropes and static ropes. Dynamic ropes are designed to absorb the energy of a falling climber, and are usually used as Belaying ropes.
