It’s an essential tool that everybody needs to pick carefully since it has to fit right, be comfortable, and most importantly, get the job done. And for skinny guys particularly, finding the best climbing harnesses that provides all these criteria is a challenging task. That’s because most brands don’t adapt their products for skinnier body shapes. With that being said, We’ve looked all over the internet to find and test the best climbing harness for skinny guys. This selection was based on quality, fit, comfort, and people’s testimonials.

In this article, we’ll talk about how climbing harnesses should fit skinny guys, as well as the best ones currently on the market.

How Should Climbing Harnesses Fit Skinny Guys?

As a skinny guy, I understand how frustrating it can get, not only to find the best fitting climbing harnesses but also pieces of clothing in general. Your body shape and skinny arms and legs limit your options and make it more difficult for you to choose. 

In order to find the perfect fit for your climbing harness, you need to look at three main components, the waistband, leg loop, and the back straps. They all work in harmony to bring you the right fit and comfort. 

Let’s take a look at how each component should fit:


This is the most important part of the climbing harness and the one that should fit perfectly. That’s because if it doesn’t, you’ll feel so much uncomfortable since it sits around the waist which is a pretty sensitive part of the human body. 

  1. The first thing that you need to do is to measure the size of your wait. That’s because most brands will have a guideline chart to identify the right size according to your waist measurement. 
  2. Place the waistband a little bit above your hip and tighten it so that it doesn’t fit too loose but also not too tight. 
  3. If you do it and it sits comfortably around your waist, then the harness that you chose passed the waistband test.

Leg Loops

Leg loops are also an important component of a climbing harness since the waistband by itself isn’t enough to keep you balanced while hanging on a rope. And because it sits around the legs, it should fit perfectly otherwise it’s just going to make uncomfortable.

  1. Just like your waist, you also need to measure the circumference of your legs in order to find the best fit according to each brand’s sizing guideline chart.
  2. Before trying on the leg loops, make sure that the waistband fits perfectly first since they both go together in harmony and right-fitting leg loops are useless if the waistband doesn’t fit right. 
  3. Make sure to tighten the leg loops until you can comfortably fit your hand between them and your legs.
  4. After you do everything correctly, your legs should have a full range of motion. If that’s not the case, then the leg loops are probably too tight or the back straps which we’ll see in the next section are limiting your movements.

Back Straps

This is probably the first time you’re going to hear this term since it’s pretty obscure when it comes to climbing harnesses. I’m talking about the part that connects your legs to the back part of the harness. It’s not as important as the other components but as a skinny guy, you need to pay attention to every detail.

  1. Before even taking this part into consideration, both the waistband and leg loops need to fit perfectly since they’re the most important in terms of comfort.
  2. If your leg loops aren’t too tight but you still can’t move your legs comfortably then it’s probably because of the back straps.
  3. If that’s the case, then you should loosen them up a little bit, or find other climbing harnesses that have longer back straps since not all of them are adjustable. 
  4. Make sure to test the back straps while hanging from a rope since that’s the ultimate test for it. 
  5. The right fit of the back straps will allow you to comfortably hand on the rope while using little to no core strength at all. If that’s not the case then test all your available options until you’re satisfied.
