Metolius 18mm Nylon Open Loop Sling Review

The Metolius 18mm Nylon Open Loop Sling: A Review After Real Use

When the need for a reliable and straightforward rigging accessory arises, the Metolius 18mm Nylon Open Loop Sling emerges as a contender. As an equipment specialist with over a decade of experience across diverse environments, I’ve come to appreciate simplicity and functionality. My search for a durable, no-frills sling for anchor building and general utility led me to this particular model. It promised robust construction and a functional design, attributes I always seek. I had previously relied on a mix of generic webbing and higher-end slings, but the specific requirements of some anchor setups, particularly those demanding a slightly wider webbing for better knot tying and load distribution, pointed me towards something like this. My initial impression upon unboxing was one of solid craftsmanship; the stitching appeared secure, and the nylon felt substantial, offering a reassuring heft without being overly bulky. It was a welcome departure from some flimsier, budget options I’d encountered.

The specific scenario that prompted this exploration was during a recent multi-pitch trad climbing trip. We were establishing anchors on a less-than-ideal rock face, and the existing anchor material was wearing thin. I needed a quick, reliable way to extend a piece and create a more bomber anchor system, and my usual assortment felt either too narrow or too specialized. This Metolius sling, with its 18mm width, immediately struck me as a good candidate. It offered a balance between the flexibility of narrower slings and the more substantial feel of wider cordage or sewn runners. My immediate thought was a sense of practicality; this wasn’t a flashy piece of gear, but one designed to perform a critical task without fuss. It was the kind of item that, when you need it, you really need it to perform flawlessly.

First Use Experience

My first real test of the Metolius 18mm Nylon Open Loop Sling occurred on a chilly autumn day at a local crag. I was primarily focusing on setting up top ropes for some introductory climbing sessions and building multi-point anchors on bolted stations that had seen better days. The ease with which this sling integrated into my existing rack was immediately apparent; it clipped onto my harness just like any other sling, the 18 mm webbing feeling substantial but not unwieldy. The open loop design proved exceptionally versatile for clipping various carabiners and for threading through anchor bolts, allowing for quick adjustments.

Throughout the day, which involved repeated loading and unloading of the anchor, the sling performed admirably. It handled the friction of passing through carabiner gates and the pressure of the rope without any noticeable degradation. Even when exposed to a light dusting of chalk and a brief encounter with damp rock, its integrity remained unquestioned. The Nylon fabric did not show any immediate signs of abrasion, and the stitching remained tight and secure. It was reassuring to have a piece of gear that felt so straightforward to use; there was no complicated mechanism or learning curve, just reliable functionality from the get-go.

Extended Use & Reliability

Over the following months, this Metolius sling became a regular fixture on my climbing rack, seeing use in a variety of settings, from single-pitch sport climbing to more involved multi-pitch adventures. Its utility extended beyond anchor building; I found myself using it as a quick extender for gear, a temporary hauling line shortener, and even as a makeshift daisy chain in a pinch, though not for dynamic loads. After approximately six months of consistent use, the sling still exhibits excellent durability.

The 18 mm webbing has softened slightly with use, which actually improves its handling and knotability, but it has not lost any of its structural integrity. There are no signs of fraying at the edges, nor any stiffness that would indicate material fatigue. The stitching remains immaculate, a testament to Metolius‘s manufacturing standards. Compared to some of the thinner, more generic nylon slings I’ve used in the past, which would show signs of wear much sooner, this model has held up exceptionally well. Its maintenance is also refreshingly simple; a quick rinse with water after a muddy outing and a period to air dry is all that’s typically needed.

Breaking Down the Features of Metolius 18mm Nylon Open Loop Sling

Specifications

The Metolius 18mm Nylon Open Loop Sling is designed with fundamental climbing and rigging needs in mind. Its core specification is the 18 mm webbing, which provides a good balance between strength and flexibility. This width offers a larger surface area for tying knots, distributing load more evenly, and providing a more comfortable grip than narrower slings.

The sling boasts a significant breaking strength of 22 kN, a critical metric ensuring its safety and reliability in load-bearing applications. Constructed from durable Nylon, it is engineered to withstand the rigors of outdoor use and repeated stress. It comes in a generous 46 in length, offering ample versatility for various rigging configurations.

The weight of just 0.7 oz makes it an almost negligible addition to one’s gear, contributing to an overall lighter load without compromising on utility. The sling is CE/UIAA certified, indicating it meets stringent international safety standards for climbing equipment. The “Assorted” color designation suggests a practical approach where function trumps specific aesthetics, which is often the case with workhorse gear.

Performance & Functionality

In its primary role as an anchor sling or rigging component, the Metolius 18mm Nylon Open Loop Sling performs exceptionally well. The 18 mm width is a standout feature, making it considerably easier to manipulate and tie into secure knots like the overhand or figure-eight. This superior knot-tying capability directly translates to more reliable anchors and better load distribution.

Its strength, rated at 22 kN, provides a substantial safety margin for typical climbing and rigging scenarios. The Nylon material feels robust and handled friction from carabiners and rock surfaces without complaint during extended use. While it is not designed for dynamic fall arrest, its static strength is more than adequate for its intended applications, making it a dependable component in any anchor system.

The 46-inch length offers considerable versatility, allowing for adjustments in anchor redundancy and extension. This length means it can be used to equalize multiple anchor points effectively, or to create a more balanced clove hitch on a carabiner. The sheer practicality of this sling in creating solid, reliable anchors is where it truly shines.

Design & Ergonomics

The design of the Metolius 18mm Nylon Open Loop Sling is a study in functional simplicity. The open loop configuration is its defining ergonomic characteristic, offering a large, uncluttered space for carabiners or for threading through anchors. This open design prevents the sling from twisting or snagging unnecessarily, which can be a common issue with sewn loops.

The Nylon webbing itself has a pleasant, slightly textured feel that provides a good grip, even when hands might be cold or damp. Its 18mm width feels substantial in hand, providing confidence and control when manipulating it. There’s no unnecessary embellishment; the construction is clean, with precise stitching at the junction of the loop, reinforcing its robust nature.

While there are no specialized ergonomic features like contoured grips or adjustable components, its inherent design is highly ergonomic for its intended use. It lies flat when not in use, clips easily to gear, and is straightforward to handle under pressure. This lack of complexity is a significant advantage in high-stakes environments.

Durability & Maintenance

The durability of the Metolius 18mm Nylon Open Loop Sling is one of its most compelling attributes. Built from heavy-duty Nylon, it is designed to endure abrasion, UV exposure, and repeated loading cycles that are inherent to climbing and rigging. The 22 kN breaking strength is a solid indicator of its resilience.

Maintenance is minimal, which is ideal for busy users. After use, particularly if exposed to dirt or moisture, a simple rinse with clean water and allowing it to air dry thoroughly is sufficient. It’s important to inspect the sling for any signs of significant abrasion, cuts, or damage to the stitching before each use, as with any piece of safety equipment. The substantial Nylon material suggests a long service life for a product used appropriately for static applications.

Potential failure points, as with any webbing product, would be deep cuts or severe abrasion that compromises the integrity of the fibers. However, the 18mm width provides a good buffer against minor scuffs. Storing it out of direct sunlight when not in use will further prolong its lifespan by protecting the Nylon from UV degradation.

Accessories and Customization Options

The Metolius 18mm Nylon Open Loop Sling is fundamentally a single-purpose, highly effective piece of equipment. As such, it does not come with integrated accessories or extensive customization options in the traditional sense. Its utility is in its standalone design and the open loop configuration.

However, its compatibility with standard climbing hardware is exceptional. It readily accepts a wide range of carabiners, from standard locking carabiners to those with large gates, thanks to the generous loop opening. For rigging, it can be easily combined with other slings, cordelettes, or anchor-building materials to create redundant anchor systems.

While not a customization option in itself, the 46-inch length can be considered a functional “preset” that offers broad applicability. Users can, of course, tie knots into the sling to shorten its effective length, thus customizing its application for specific anchor configurations. But in terms of add-ons or factory modifications, this sling is a purist’s tool.
