Rock climbing is an exhilarating sport that demands both physical strength and mental focus. Whether you’re scaling outdoor cliffs or testing your limits at an indoor gym, safety is a top priority. One of the most crucial pieces of gear for climbers is the harness. A well-fitting harness ensures your safety and comfort, allowing you to focus on the climb ahead. This article will walk you through the process of sizing a rock climbing harness correctly, ensuring that your gear works as it should when you’re on the wall.
What Is A Rock Climbing Harness?
A rock climbing harness is a piece of safety equipment worn by climbers to secure themselves to a rope or other climbing gear. The harness helps to distribute the force of a fall over the body, minimizing injury. It typically consists of leg loops, a waist belt, and gear loops for carrying essential tools. There are different types of harnesses depending on the style of climbing, such as sport climbing, trad climbing, and mountaineering.
Choosing the right harness is essential for comfort, performance, and safety. One of the first steps in this process is making sure it fits correctly.
Why Proper Sizing is Important
Proper sizing is essential for several reasons:
Safety: An improperly sized harness may not properly distribute the force in the event of a fall, putting you at risk of injury.
Comfort: A harness that’s too tight can cause discomfort, chafing, and bruising, while one that’s too loose might shift or slide during the climb, distracting you and potentially affecting your performance.
Performance: A well-fitting harness allows for greater freedom of movement, helping you focus on your climb without any hindrances.
How to Measure for a Rock Climbing Harness
Before you buy a harness, it’s important to take some basic measurements to ensure the right fit. The two key measurements you’ll need are your waist and thigh circumference. To do this, you’ll need a flexible measuring tape.
1. Waist Measurement
Step 1: Stand up straight and breathe normally.
Step 2: Use the measuring tape to measure around the narrowest part of your waist, which is typically just above your hip bones.
Step 3: Ensure that the tape is snug but not tight, as you don’t want it to compress the skin.
2. Thigh Measurement
Step 1: Stand with your feet shoulder-width apart.
Step 2: Wrap the measuring tape around the widest part of your thigh, typically around your upper thigh, just below your groin.
Step 3: Make sure the tape is snug but not so tight that it leaves a mark or restricts blood flow.
3. Inseam Measurement (Optional)
For certain types of climbing harnesses, such as mountaineering or alpine harnesses, you may need to measure your inseam. This is particularly true for harnesses that feature a full-body design. To do this:
Step 1: Stand with your feet slightly apart.
Step 2: Measure from your crotch down to your ankle bone, ensuring the tape follows the natural curve of your leg.
Once you have your waist and thigh measurements, you can compare them with the sizing charts provided by most harness manufacturers.
These charts will give you a size range based on your measurements, but it’s important to note that sizing can vary slightly between brands.
Types of Rock Climbing Harnesses
There are a few different types of harnesses to consider when shopping for one. The type you choose will affect how the harness fits and performs.
1. Traditional Harness
Traditional harnesses are great for a wide range of climbing activities, from sport climbing to trad climbing. They typically feature adjustable leg loops and a padded waist belt. These harnesses are designed to offer maximum comfort for long climbs.
Sizing Tips: Traditional harnesses usually come in multiple sizes (S, M, L) based on waist and thigh measurements. However, the leg loops are often adjustable, giving you more flexibility.
2. Sport Climbing Harness
Sport climbing harnesses are designed for short climbs where speed and agility are key. They tend to be lightweight and minimalistic, with less padding than traditional harnesses. They are often designed with adjustable leg loops and a more streamlined waist belt to provide a snug fit and reduce weight.
Sizing Tips: These harnesses often have more specific sizing options and are meant to fit snugly around your waist. Look for a model with adjustable leg loops if you plan to wear it over multiple layers of clothing.
3. Alpine and Mountaineering Harness
These harnesses are designed for alpine or ice climbing, where you may need to wear additional layers of clothing or gear. They offer features such as adjustable leg loops, a reinforced waist belt, and lightweight material that won’t slow you down.
Sizing Tips: The sizing of alpine harnesses is often flexible, with adjustable straps for both the waist and legs. They tend to have a larger range of adjustments, as climbers often wear bulky clothing in cold environments.
4. Full Body Harness
Full-body harnesses are typically used by beginners, children, or climbers who need extra support, such as those participating in climbing instruction or indoor gym climbing. These harnesses offer additional support and security by including both a waist belt and leg loops.
Sizing Tips: Full-body harnesses are usually adjustable and designed to fit a wide range of body shapes, including children. Be sure to adjust the straps properly to ensure a snug but comfortable fit.
Harness Fit: How to Know if It’s Right for You
Once you’ve chosen your harness, it’s time to test the fit. There are several ways to determine if your harness fits properly.
1. Waist Belt Fit
Snug but not tight: The waist belt should sit comfortably around your waist without pinching or rubbing. You should be able to fit a finger between the harness and your body, but it should not move up or down when you’re standing or walking.
Adjustable: Most modern harnesses come with adjustable waist belts, allowing you to customize the fit. Ensure the harness is secured tightly but not too tight, as it can restrict your movement or circulation.
2. Leg Loop Fit
Comfortable and secure: The leg loops should fit snugly around your thighs without cutting off circulation. You should be able to move your legs freely, but the leg loops should not slide up or down when you move.
Adjustability: Many climbing harnesses come with adjustable leg loops to ensure a precise fit. When adjusted correctly, the harness will fit comfortably, even during extended climbs.
3. Test the Harness
After putting the harness on, take a few moments to test it:
Stand up: Make sure the harness sits comfortably around your waist and legs.
Sit down: Practice sitting on the harness, as it’s important to feel comfortable when you’re in a seated position. This will help simulate the feeling of being in a harness for a long climb.
Move around: Perform dynamic movements such as squatting, stretching, or twisting to ensure the harness allows full mobility. The fit should be snug, but it shouldn’t hinder your range of motion.
Other Considerations for Choosing a Rock Climbing Harness
In addition to size, there are several other factors to consider when choosing the right harness for you.
1. Padding
If you’re planning on long climbing sessions, consider a harness with extra padding for comfort. A well-padded waist belt and leg loops will help reduce pressure points and chafing.
2. Gear Loops
If you plan on carrying climbing gear such as quickdraws or carabiners, check for a harness that has gear loops. Most harnesses feature one or two gear loops, but advanced models can have several.
3. Weight
For sport climbing or mountaineering, weight is often a key consideration. A lightweight harness will reduce the overall load you carry, which can be especially important when climbing over long distances.
4. Adjustability
Look for a harness with adjustable straps, especially in the leg loops and waist. This feature allows you to fine-tune the fit and is especially useful if you gain or lose weight or wear different layers of clothing.
Conclusion
A properly sized rock climbing harness is essential for both your safety and comfort. By taking the time to measure your waist and thigh circumference and trying on different harnesses, you’ll be able to find the right fit for your climbing needs. Remember to check the fit regularly, especially if you gain or lose weight, or if you’re climbing in different weather conditions that may require additional clothing.
