Sterling’s CanyonPrime canyon rope is designed specifically for canyoneering use.

Due to tis design and measurements the CanyonPrime is a perfect choice for those who have started to be involved with canyoneering.

This climbing rope is a static rope that is water resistant and light weight.

Made with a variety of lengths and two-color options, orange and white or blue and green, you can easily find the best rope to start off your canyoneering experience.

A Sterling CanyonPrime review shows the value of this climbing rope through its design and the materials used to create it, making it easier for you decide if this is the rope that will best suit your needs.

Static Rope

What type of rope you will be needing for your canyoneering trip is very dependent on what type of climbing course and style you will be performing.

Two of the most prevalent rope choices are dynamic and static ropes.

Sterling’s CanyonPrime is a static rope, meaning it will not stretch during climbs and uses.

This makes the climbing rope good for climbs involving ascending or for hauling loads up the rope due to the lack of stretch a static rope provides.

Lack of stretch is important for many climbing experiences; in fact, most canyoneering ropes are technically static ropes because they are not made to absorb any large shocks.

Without the stretchiness of the rope, there is less bouncing, discomfort during rappelling movements, and a less likely chance of the rope being cut over sharp rock edges.

So, the less stretch for a canyoneering rope means it will be better suited for more climbing styles.

Static ropes are not designed to be used for certain climbs though, such as top roping or lead climbing.

These climbs are designed to have a heavier load and therefore need some stretch in order to prevent overstraining the rope and make movements more fluid.

For these climbing routes, a dynamic rope is preferred.


The weight and strength of your rope is based heavily on the diameter of the climbing rope, along with the rope’s length.

Static ropes come in a variety of diameters, usually anywhere between 9 millimeters to 13 millimeters.

The CanyonPrime rope features a diameter of 8.5 millimeters for its core.

This makes the climbing rope skinnier than the average rope size.

The thin nature of the diameter makes the rope lighter in weight and more compact for easier packing.

Yet, larger diameter ropes are stronger than thinner diameters such as this rope’s diameter.

Larger diameters also feature less stretch, are more durable and abrasion resistant, and are easier to control and tie properly.

The compromise for weight and compactness is the lose or lessening of these abilities in the CanyonPrime rope.

The low diameter can also be a problem for those just now beginning to climb canyons, as skinner climbing ropes require greater skill in order to safely utilize them and connect them to other equipment.


Static ropes come in a wide variety of lengths and the CanyonPrime rope is no exception.

Sterling sells the ropes in sizes of 100, 150, 200, 300, and 660 feet.

Each of the measurements, such as the weight and elongation of this rope in the article is based off the 200-foot sized climbing rope, an average length for most canyoneering experiences.

The length and amount of rope you bring depends on the depth and drop of the canyon you are climbing, the number of people you will be climbing with, and just how much rope you can carry with your gear.

For indoor gym use, consider using a shorter rope length due to the gym’s climbing courses smaller length.

Some gyms may even come equip with their own rope for you to use.

Ropes around 100 feet long are sufficient for these climbing courses.

Outdoor climbing courses require at least half the length of the route vertically.

Many canyons are completed with the use of two 200 feet ropes, though smaller sizes can be sufficient too.

Sheath and Core

The sheath, or outer material, of the rope has a tested slippage of 0.40 millimeters and makes up 51.95% of the rope’s mass.

Since the majority of the rope’s mass comes from the sheath, the rope is more resistant and durable to abrasion.

Both the sheath of the rope, and the core are made completely of polyester material.

This is a low-cost material that has little to no stretch, making it a good option for static ropes that naturally have limited stretching.

Polyester is also a good material choice for your rope due to the strong resistance to abrasions and overall durable nature.

Especially within an canyoneering route outside, your rope will be exposed to several different elements: sharp rocks that can tear, rough terrain that can wear down fibers, water and sunlight which can drain your rope’s functions, and the constant pull of weight being forced on the ropes structure.

Having a durable material cannot only help prevent these problems to affect your rope but also create a longer lifespan for your rope.

Another function of polyester material in climbing ropes is its ability to resist water.

Whether its moisture created from sweat or the water from weather conditions or water featured in climbing routes, the sheath and core will suffer no significant reduction in strength.

The rope will also not grow heavier when ever wet and will dry much more quickly than other rope materials.

This helps give you an ability to allow you to better stay in control of your rope whenever you experience rope.

Furthermore, this feature expands your rope’s life as it will not be as easily damaged by watery conditions.

The sheath of the CanyonPrime rope features a softer hand, to offer a smoother rappelling experience, greater handling, and makes it easier for you to pack the rope with the rest of your gear.

This feature also gives you greater friction whenever you are rappelling.


Since your rope will be the heaviest piece of equipment you bring for canyoneering, the weight of your rope is important.

The longer and thicker a climbing rope is, the heavier the rope will be overall.

The average climbing rope weighs around 58 grams.

The CanyonPrime climbing rope weighs 56.4 grams, putting it just barely below the average static rope’s weight.

This is due to its thin nature caused by the lower core diameter and lightweight outer portion.


The durability of your rope is important for more than one reason; it not only helps you determine if a climbing rope will work best for your weight and climbing experience, but also whether or not the rope will last for a long time after use.

As mentioned, the polyester material used in both the sheath and the rope’s core is durable and resistant to abrasions caused by the rough and sharply edged rocky surface of outdoor canyon climbing routes.

The durability of your climbing rope also depends on the tested breaking strength.

While this limit is almost never reached on the average climbing trip, it is important to note just what the limit is and how it affects your rope.

The breaking strength of a rope shows the impact force of the rope. The lower the impact number means less force towards a climber who is falling.

The lower impact number also means the landing after a fall will be softer and more stretch within the rope.

The Sterling rope has a rating of 17.0 kilonewtons, putting it at a higher number compared to other climbing ropes with a similar diameter.

No matter the rope you use, or how durable it is, you should retire a climbing rope after an average of ten years.

This number can be less based off the frequency of the rope’s use.

Most ropes will not last dedicated climber’s ten years.

Other ways to monitor your rope’s durability besides time is to monitor its physical condition.

Watching for damages like tears, rips, worn fibers, abrasion sports, and even areas that have been faded by the sun or improper cleaning can help show just how many uses your rope has left.

If your rope has any tears or cuts in it, do not use it to climb.

Other Features

The elongation of this climbing rope is set at a elongation of 1.65% at 300 pounds of weight.

This is the amount of stretching caused within the rope with an 80 kilogram weight hanging from it.

The higher the elongation indicated there is less efficiency. This is due to the energy being wasted whenever the rope stretches.

Ropes need less than 10% of elongation, which the CanyonPrime well below, making it a decent rating.

The minimum tension rope that a rope should break at whenever it is new for the CanyonPrime climbing rope is set at 3,821 pounds of force.

Sterling CanyonPrime Review: Right for you?

The CanyonPrime rope is a strong and durable static rope with no stretching or elongation to its design, making it a good canyoneering rope.

This rope is light weight due to its thinner diameter core, with a weight of 56.4 grams and a diameter of 8.5 millimeters.

With both the core and sheath of the rope consisting of polyester, the entire rope is made to be abrasion resistant and hydrophobic.

This ability to not let water affect the weight, control, and integrity of the rope’s abilities is a good function for ropes to be used in outdoor climbing courses.
