Climbing bags: You’ll need a climbing bag to carry all your equipment. Chalk bags hold rock climbing chalk, which is frequently used by both rock and indoor climbers. They’re usually clipped onto a harness for easy access.

Belay devices: A belay device controls a rope’s movement. Used for ascending and descending, it acts as a brake by applying friction.

Cams: You insert spring loading camming devices (or cams) into the cracks or pockets of a rock. A cam, such as the Black Diamond Camalot or Alien CCH, actually consists of two, three, or four cams, which are mounted on an axle. Once this protection device is inserted, you pull the axle; the cams are then spread farther apart and lock into place.

Carabiners: Rope runs through these metal loops that have spring-loaded gates. Carabiners are connectors: they attach rope to a fixed anchor, such as a cam or nut. Quickdraws consist of two carabiners connected by a short loop of webbing.

Climbing holds: Climbing holds attach directly to a climbing surface, providing a better grip.

Climbing apparel: Climbing apparel options run the gamut from shorts with pockets designed specially for climbing gear to an array of shirts, pants, gloves, and sunglasses.

Climbing footwear: Climbing shoes from companies such as Scarpa, Five Ten, and La Sportiva are a must for any type of climbing. The stiff rubber soles on climbing shoes offer the support and traction you’ll need.

Harnesses: This is what links you to your climbing rope. Harnesses fit around your waist and legs, offering support and safety. Black Diamond and Petzl both manufacture harnesses of different sizes and shapes.

Helmets: Don’t overlook the importance of a helmet. Helmets offer protection not only if you fall but from falling objects as well.

Nuts: Another protection device that you insert into the cracks of a rock, nuts consist of small metal wedges that are threaded on a wire.

Climbing rope: Available in different lengths, strengths, and diameters, climbing rope generally comes in two types: single rope or double rope (also called half rope). You can also purchase rappelling rope, rope bags, cords, and slings.
