Climbing Slings Buyer’s Advice

Climbing slings are an essential piece of climbing gear that every outdoor enthusiast needs to have in their kit.

Whether you’re a beginner or an experienced climber, investing in high-quality climbing slings can make all the difference in your safety and performance on the rock.

However, with so many different types and brands of climbing slings available on the market, choosing the right one can be a daunting task.

That’s where this climbing slings buyer’s advice comes in.

We will be taking a closer look at the key factors to consider when choosing climbing slings, including materials, length, and width.

Consider the material used when selecting a climbing sling

When selecting a climbing sling, it is important to consider the materials used in its construction.

Climbing slings are made using a variety of materials such as nylon, Dyneema, and Spectra.

Nylon slings are durable and affordable, making them a popular choice for beginners and those on a budget.

Dyneema and Spectra slings are lightweight and strong, making them a preferred choice for experienced climbers who rely on their gear for safety.

However, these materials are more expensive and may not be as resistant to abrasion as nylon.

It is important to also consider the possible environmental impact of the materials used and select slings that are made with sustainable practices and materials that can withstand regular use and abuse.

Ultimately, the material used in the construction of a climbing sling will impact its strength, weight, and durability, making it a critical factor to consider when making a purchase.

Understand the differences between sewn and knotted slings

When it comes to climbing slings, it’s important to understand the differences between sewn and knotted slings.

Sewn slings are made by joining two ends of a flat nylon webbing and sewing them together using a designated bar tack stitch.

These slings offer a consistent width and strength along their entire length, and are suitable for a variety of uses, including anchor building and extending placements.

On the other hand, knotted slings are made by tying a knot in a continuous loop of cord or webbing.

While they tend to be less expensive and lighter than sewn slings, knotted slings can be difficult to untie after being loaded, and their strength can vary depending on the type, thickness, and tightness of the knot.

It’s important to consider the intended use and personal preference when choosing between sewn and knotted slings, as different situations may require different types of slings.

Review the load rating of the sling

When selecting a climbing sling, it is essential to consider the load rating of the sling.

The load rating refers to the maximum weight that the sling can handle without breaking.

Climbing slings come with a load rating that is indicated in kilograms or pounds.

It is important to remember that exceeding the load rating of your sling can result in severe injury or even death.

Manufacturers usually indicate the maximum load the sling can carry on the product itself, and it is advisable to take note of this before purchasing.

Be sure to review the load rating of the sling and ensure that it is suitable for the type of climbing you intend to undertake.

Different types of slings are rated for different loads, so make sure you get a sling that is rated for what you need.

Failure to adhere to the load rating of your sling can result in severe accidents, and as a responsible climber, it is your duty to ensure that you are purchasing a sling that meets your needs and is within your skill level.

Check the quality of the stitching

As you consider purchasing climbing slings, one important aspect to keep in mind is the quality of stitching.

The strength and durability of a sling are only as good as the stitching that holds it together.

Ensure that the stitching on the sling you are considering is neat, strong, and properly executed.

Check for any loose or frayed threads, as well as uneven stitching or thread color changes, as these can be signifiers of a lower-quality product.

If possible, it is recommended to physically examine and handle the product before making your purchase decision, as this will allow you to closely inspect the stitching and assess the quality firsthand.

Additionally, researching the brand’s reputation for quality and craftsmanship can give added confidence in the product’s construction.

Consider the length of the sling for the specific activity

When selecting a climbing sling, it is essential to consider the length of the sling for the specific activity.

The length of the sling can vary from 30cm to 240cm, and this will determine the range of different types of placements that can be made.

Shorter slings are generally used for setting up anchors, while longer slings are best for extending anchors or creating belays.

A standard-length sling is about 60cm and is suitable for most applications, including clipping into anchors or building gear anchors.

Longer slings, on the other hand, are useful when extending a piece of protection to reduce rope drag, such as on a wandering route or on an overhang.

It is crucial to choose the appropriate length of the sling to ensure that the anchor or protection point is safe and secure and to ensure smooth rope management during the climb.

Secondly, it is more versatile and can be used in a wider range of situations, including aid climbing and big wall climbing, where you need to be able to move up and down the rope easily.

Finally, a dynamic sling is generally lighter and more compact than a static one, making it easier to carry and store when you’re not using it.

They can be used to secure gear to a backpack, as a clothesline, for makeshift shelter building, and for various other purposes where a strong and durable strap may be needed.

However, it is essential to note that climbing slings are specifically designed and tested for climbing purposes, so using them for other purposes may affect their strength and durability.

It is always best to consult the manufacturer’s instructions and guidelines before climbing slings for any purpose other than climbing.
