Whether you are a seasoned rock climber or an amateur, a rock climbing harness is one of the most essential pieces of rock climbing gear you can get. It determines whether you get to survive should you lose your grip. As such, you need to ensure that the harness you use is dependable and durable.

Aside from the material quality and build aspect, you also need to ensure that it has the correct features for rock climbing usage, such as the waist buckle and the rope loops. Additionally, you need to ensure it is the right fit and design for your body shape. No one wants to develop a numb feeling in their legs when climbing a rock due to inappropriately sized leg loops or poor waist belt to leg strap ratio, among other factors.

As such, you need to ensure that you have the right rock climbing harness for you before you go rock climbing. This comprehensive guide aims to help to choose a rock climbing harness.

Parts of a Climbing Harness

Essentially, the waist harness connects you to the climbing rope. Its components are essential in making sure you stay on the rope and climb up with ease while staying safe. Here are the parts of the climbing harness;

  1. Waist belt

This is a thick strap that wraps around your waist to secure the harness to your body. Most waist belts are padded for comfort, but this tends to make them bulkier and heavier. There are waist belts that are not padded, but these are more common on alpine climbing harnesses.

  1. Leg loops

These are designed to stabilize your body when wearing the harness. This helps to distribute your body weight between your legs and pelvis. They help lessen the impact of a fall and make it easier to support yourself on a rope.

There is one loop for each leg, and they are usually attached to the front of the waist belt. The loops are designed to encase your thighs, and their fit can be adjusted by tightening or loosening the webbing, which runs through buckles.

  1. Buckle

The buckle helps to connect the harness to the rope and the leg loops to the waist belt. It is located at the front of the waist belt, just like in a regular belt. The buckle can be a single or double buckle.

For increased safety, a double buckle is best for rock climbing as it prevents the harness from coming undone while you are rock climbing. Some buckles also come pre-threaded to make it easier to loosen and tighten your harness.

  1. Tie-in loop

This is a rigid loop sewn into the front of the waist belt to secure the buckle. It also helps to offer extra rigidity to the rope after it is tied to the harness. This is due to the rope threading technique, where the rope is passed through the leg loop cross and the tie-in loop. This, in turn, helps in weight distribution alongside the leg loop support.

  1. Belay loop

This loop attaches the leg loops to the waist belt. It is considered one of the most essential components of a climbing harness. It is used to attach a locking carabiner for belaying and rappelling purposes.

The belay loop is supposed to be extra strong to withstand climbing tugs, rubbing friction from the carabiner, and fall impact. It is crucial to replace the belay loop once it starts to get old and worn out.

  1. Gear loop

As the name suggests, this loop essentially stores your climbing gear, making it easy to access as you rock climb. The gear loop can either be a soft or rigid loop attached to the waist belt. You can use it to hold your quick draw, nuts, and cams.

Harnesses come with two or four gear loops. Smaller harnesses such as kids’ and women’s harnesses generally have two gear loops. Standard size men and unisex harnesses usually come with four gear loops. More loops equal better gear tracking. Ideally, you should not attach anything heavy to your gear loop.

  1. Haul loop

This is similar to a gear loop but is attached to the back of the waist belt. It is typically used to carry a second rope. Some harnesses have a full-strength sewn-in haul loop. While some have a plastic loop inserted into the waist belt for clipping a chalk bag or any additional gear.

  1. Leg loop cross piece

This is a piece of webbing used to connect the leg loops in front of the harness. It is adjustable using a threaded buckle and is also essential for threading the climbing rope for increased stability.

Types of Climbing Harnesses

The two main categories of climbing harnesses are the sit harness and the full-body harness.

Sit harness

As the name suggests, this is the harness worn around the waist and feels like you are sitting. It is also the primary type of harness used by both pro rock climbers and amateur rock-climbing enthusiasts.

Full body harness

A full-body harness is worn like a jumpsuit except in strap form. It is a combination of a chest harness and a seat harness. It helps to stabilize full-body posture while rock climbing, which is ideal for hauling a load when climbing. This harness type is mostly used for fire rescue.

Chest harness

This is the least common of all the harness types. This is a harness that is worn like a vest and used to hold the rope as you climb. However, there are too many risks involved as well as downsides. That it is best left to rock climbing pros. Rescuers mostly wear them in the event of a fall accident extraction or rescue attempt.

Activity-based harness categories

These are types of harnesses designed for various kinds of active sports such as mountaineering or sport climbing. They have subtle differences in design as per the specific needs of the sport. And the type of clothing you need to wear with the harness.

Here are the main types of harnesses commonly found in the market;

All-round harness

This is a harness that is suitable for types of sports. You can use it indoors or outdoors, and it usually comes with standard harness components. The harness is mid-weight and usually features adjustable loops and a waist belt compatible with different climbing gear.

Winter harness

This is a water-resistant harness designed to withstand freezing weather. They are mostly made out of closed-cell foam that does not absorb moisture.

This makes them water residents, but they cannot be used in hot weather due to their inability to breathe, making them unbearable, especially if you tend to rock climb in summer.

Alpine harness

This harness is designed to be used for mountaineering, glacier climbing, and skiing. It is made from simple webbing to reduce its weight, and it is made from wet weather-resistant materials. It also has an easy-wear design and can be worn over full skiing gear.

Trad harness

This is a traditional climbing harness built for camping rock climbing outdoor adventures. They tend to have at least four gear hoops for tracking gear and a large rack to accommodate extra loops. They feature adjustable leg lops and rear haul loops.

Sport harness

Unlike the other harnesses, this one is designed to be light to reduce energy consumption when participating in climbing for sports purposes. This type of harness usually has a minimal amount of hardware, and it is stripped down to the bare essentials depending on the climbing terrain and environment.

They usually feature fixed leg loops, breathable foam padding, and at most two gear hoops, as you mainly need the quickdraws when sport climbing. It is also popular among alpine climbers.

Things to consider when choosing a climbing harness

  1. Fit

Ensure that the harness you select fits you and will still fit you should you need to wear it with extra clothing layers. It should also have wiggle room to ensure you are comfortable, especially when wearing it for a longer climb.

  1. Type of harness

Getting the right type of harness for your rock climbing needs is necessary. Ensure you get a harness with the right components, such as the right number of gear loops, as it is crucial to haul your climbing gear hands-free.

  1. Quality of the harness

A good quality harness should be made from durable tear-resistant material that can withstand harsh weather elements and constant friction, especially the loops.

How to size for a climbing harness

The general rule of thumb is to have enough wiggle room in your harness to fit three-five fingers after the straps are buckled. The key is to have a snug fit that is not too tight. Bear in mind that you will not be wearing layers of clothing when trying on your harness, and you might need to wear layers of clothes when rock climbing.

You should also have a bit of tail on your waist belt and leg loops. This wiggle room is essential when rock climbing. The harness should sit above your hip bones, and it should have enough belt strap for cinching and then some.

Once the harness is buckled, it should not be able to slip past your hips. The leg loops should also be snug enough to slip your hand between the leg and the loop. Once you find a size that fits you from a particular brand, you should be able to purchase a harness online with ease.

If shopping in-store is not an option, here is an easy guide to help you measure yourself to determine your correct harness size;

Items needed

  1. Clothes tape measure
  2. Notepad and pen


  1. Waist measurement

Measure your waist around your iliac crest areas, which is the area just above your hip bone. Leave enough wiggle room to ensure your waist belt is not too tight when buckled. It should also not be roomy enough that it can slip past your crest.

The measurement should be extra for the extra strap length as you do not want to be cinched to the end of the waist belt. This will ensure that your gear loops have attachment room. You should also account for layers of clothing when noting down your ideal waist belt size.

  1. Leg loops measurement

Measure the circumference of your thighs and allow for wiggle room to leave room for clothing layers. This is only necessary if you are buying a harness with adjustable leg loops. A harness with elastic leg loops does not require wiggle room addition.

  1. Rise measurement

The rise is the distance between your thighs and the waist belt. While it is necessary to have a loose rise between the waist belt and the leg loops, it is essential to ensure that it is too short or too long.

The former can cause you to tip backward, while the latter will exert pressure on your waist belt due to poor weight distribution. This is especially difficult when shopping for harnesses for a child or if you are a woman. This is because women ten dot has a smaller waist and a larger rise due to the curved silhouette. This makes it extremely crucial for you to get the correct fit before picking a harness. On the other hand, kids have a smaller body making a full-body harness the best option.
