The harness is the first protection of any climber. Defined simply, the harness secures the climber to the rope or an anchor point. It is worn around the waist and thighs, and is usually made of sewn nylon; foam and mesh are usually added to provide comfort for the climber. Thicker straps and padding provide better comfort for long climbing sessions.
2. Climbing shoes
A climbing shoe is no ordinary shoe - it is a specialized type of footwear designed for the sport and has three major categories: neutral, moderate, advanced. Choosing the perfect child or shoe is essential, so you must know at least the pros and cons of each one. Do not feel pressured to choose "the best ones" though: even the most experienced climbers may still prefer a neutral shoe over the advanced type. It all dependent on usage, purpose and preferences.
A carabiner is one of the most important pieces of climbing gear. It allows for the rope, belay devise and everything else to be safely and easily connected. The looks can be decieving but the strenght of a single carabiner is huge. These small metal snaplinks have a gate that swings shut to close against the nose. There are different types and variants depending on the need. Binders (hose for carabiner) that have straight edges are reserved for clipping to gear. Some have threaded sleeves that can be screwed over the gate to ensure that it is tightly closed. You can check this for a more thorough breakdown of this handy gear.
4. Belay device
A belay devise is also one of the most important pieces of climbing gear. It is used for belaying the other person and thus preventing fall to the ground. The purpose of the device is to make it easier to hold the rope tightly Belay device is attached via carabiner to the harness of a belayer (person who belays) and the rope goes though it. Using the belay device properly is an essential knowledge that everyone has to master!
There are many types of belay devices with two main categories: manual such as ATCs and semi-automatic such as GriGri, Reverso and many more. Semi-automatic devices are generally safer for beginnesr as they allow for tiny mistakes to go unpunished. But before using any, read manuals properly, try them and before every climb, make a proper check that belay devide is properly attached to the harness, the rope and that you are holding the rope the correct way.
5. Chalk and Chalk Bag
It's the same magic white dust that gymnasts and athletes use to have a better grip on their equipment: magnesium carbonate. Naturally a drying agent, chalk (in the form of a ball filled with dust chalk or just as loose chalk) is stored in a chalk bag that's slinged to your waist for an easy access. Chalk your hands as often as needed to keep your hands dry and to secure that extra grip strength when holding on smaller holds and slopers. Do not underestimate your chalk bag - it does not only store the chalk but if it has another pocket for your keys or brush, that would be really great. Chalk bags can have different sizes so make sure that your whole hand can fit in.
All gear is important but investing on a good harness, pair of shoes, chalk and chalk bag should be your priority. A good harness will stay with you for many years, so spending an extra euro here is a good choise. Once you transition to outdoor crags, more gear is needed. When doing sport climbing on bolted routes outdoors, the additional gear needed is very limited (quickdraws).
