Indoor rock climbing is a lot more controlled than outdoor rock climbing because everything is set up and staged to help you achieve your goals. But when you’re outside, the cliffs and rocks are set up for adventure, which means that you’ll have to consider your safety while you climb. The best climbing slings are designed to help you manage your rope and establish anchors. 

By running your climbing rope in a straighter line to your position on the rock, you’ll reduce the amount of friction and damage to your rope. In turn, this will keep you safer as you climb. But it can be difficult to choose between all the top rated slings for climbing. Here, we will provide you with the best products and buying tips so that you can find a quality sling to support you on your climbing journey.

How To Choose A Climbing Sling – Buying Guide

How_to_Choose_Climbing_Sling

Size

The best climbing slings will be available in various sizes, which means that you can choose the exact measurement that you need for your climb. The length of each sling will vary by its design and most brands provide slings that are 60-120 centimeters in length. However, you may find a climbing runner that is up to 200 centimeters long. 

Most slings will be labeled as single, double, or extra-long. A single length sling is 60 centimeters or 24 inches in length. A double length sling would be exactly double the length of a single sling, so 48 inches in length. However, a 200 centimeter or 78-inch-long sling would be considered to be extra-long. 

The sling length also corresponds to the intended climbing sling use. Shorter slings are best for setups like the alpine quickdraw, which is when you are attempting to reduce rope drag on the rocks. You can also use them for belay protections or as anchors. 

A long length sling is better for extending your rope are suited for use as multiple point anchors or to extend the length of your rope as you anchor. The extra length allows you more versatility to tie climbing knots for various setups. 

Extra-long slings will help you create extended anchors in difficult to climb places like a rock edge or overhang. The longer length just gives you more length to work with and create your anchors. 

Along with length, you should also be conscious of the width of your rope. One of the Dyneema sling designs on our list is 10 millimeters wide, which is one of the skinnier options. Skinny slings are still strong, but they are best used for lightweight climbing. If you are in more rugged locations or need a heavy-duty option, you should look at a diameter of 16 millimeters. 

Material

The material is also an important consideration when you are shopping for top rated slings for climbing because it can affect the durability and strength of the design. The best slings for climbing will be made out of a high-quality material with the three most popular options being nylon, polyester, and Dyneema. 

Nylon and polyester are both lightweight materials, which are both durable and strong. Nylon tends to be slightly stronger than polyester and the tight weave of the webbing can bear more weight. Heavier duty slings will likely be made of nylon for the added bulk and weight, which increased the overall power and strength. 

Dyneema slings are the most lightweight and are made of an Ultra High Molecular Weight Polyethylene. The material is ultra-light, while also being resistant to abrasions and UV damage. With less water absorption, Dyneema is also less likely to stretch or change shape over time. But Dyneema is not as strong as nylon, which means that it is less likely to be used as an anchor. 

Durability

Climbing sling use is centered around your safety, which means that any product you choose should be extra durable. The best climbing slings will feature a sewn-in bar tack, which will stop the sling from separating and is guaranteed to be unbreakable. But you also want the weave of the material to be durable. 

While slings are designed to reduce the amount of friction and wear on your rope, the sling itself also needs to be resistant to damage from the rocks as it holds your various climbing positions. Climbing sling reviews are the best resource to determine whether the durability of a design can be trusted or if you should continue on your search. Many reviewers will state how they use their sling and how durable the design was for their specific application, which can help you determine which sling will best suit your needs. 

Style

There are a lot of different styles of climbing and your sling can be used for all of them, but its best that you learn how to use your sling in different situations. Most climbers will use a sling for outdoor climbing, but indoor climbing can be a good place for beginners to learn how to properly setup and use a climbing runner. But if you do choose to head outdoors, you may decide to go bouldering, top-rope climbing, belaying, or rappelling. 

Bouldering is a type of climbing that uses the least amount of gear and you are not likely to be using slings in this situation. This is due to the fact that you normally don’t climb to high heights when bouldering and will rely on a crash pad instead. 

Top-rope climbing uses anchors at the top of your climbing route, which assist in your climb. You will climb towards the anchors and up the wall. Slings can be very useful in this type of climbing to setup your anchors.  

Finally, belaying or rappelling is when you assist a climber in their climb with one person who holds the rope from either above or below the person. Placements of the anchors in belaying or rappelling are safe to use with slings and many climbers will use slings for an easy knot setup. 

No matter what style of climbing you choose, slings are designed to improve your safety and enhance your overall experience on the rocks. 

Type

The vast majority of climbing slings are one type: a simple loop of strong material. The loop is closed with a sewn-in bar tack for security. With the loop, you can twist, turn, or hang the material in various ways to suit your needs. 

But some brands have unique designs. The GM CLIMBING chain design is one of the unique designs that has 6 individual loops that have been connected together to make one long sling. The chain provides more versatility because you can adjust the length of the sling, but it is definitely not the common type of sling that you’ll see on the market.

Top rated slings for climbing will be measured by length and circumference. Not all brands use the same measurements, so you will need to read the product specifications or climbing sling reviews before you make a purchase.
