Metolius Monster 11mm Open Loop Sling Review

Let Me Walk You Through the Metolius Monster 11mm Open Loop Sling

As someone who’s spent over a decade navigating the demands of outdoor adventures, workshop projects, laboratory precision, and rugged field environments, I’ve developed a keen eye for gear that truly performs. This extensive experience has taught me that sometimes, the simplest tools are the most indispensable. It was during a recent gear inventory, specifically while organizing my aid climbing and multi-pitch rack, that I realized my existing collection of slings was looking a bit tired. A few were showing signs of significant wear, and I needed a reliable replacement that wouldn’t break the bank but still offered the robustness I trust. This search led me to the Metolius Monster 11mm Open Loop Sling, a product that promised durability and simplicity.

My previous slings, while functional, were often too specific for general utility, or conversely, too flimsy for critical applications. I recalled a friend recommending Metolius for their solid, no-nonsense approach to climbing hardware, and the mention of Dyneema in the product description immediately caught my attention for its reputation for strength and low weight. Compared to bulkier nylon slings, or even some of the thinner Dyneema cords I’d used, this 11mm width felt like a promising sweet spot for versatility. My initial impression upon holding one of these slings was one of understated quality; the webbing felt dense and robust, not overly stiff but certainly substantial for its weight. There was a tangible sense of confidence in its construction, a feeling I’ve come to associate with well-made climbing hardware.

First Use Experience

My initial foray with the Metolius Monster 11mm Open Loop Sling took place on a crisp autumn day, during a series of mock aid placements on a local limestone crag. I was specifically testing its performance as a quick-draw extension and as part of a daisy chain setup for hauling. The webbing felt smooth against my gloved hands, and it slid easily through carabiners without snagging, which is crucial when you’re focused on climbing rather than fiddling with gear. Even after a few hours of repeated clipping and unclipping, and being weighted a couple of times, the sling showed no signs of abrasion or fraying.

I also found myself using this sling in a less conventional capacity back in the workshop, specifically for organizing tools. The open loop design made it incredibly convenient to hang various wrenches and pliers from a pegboard system. It handled the weight of substantial steel tools without any discernible stretch or deformation, a testament to its build. I also encountered some light dust and workshop grime during this period, and a quick wipe-down with a damp cloth was all it took to restore its appearance, highlighting its ease of maintenance.

Extended Use & Reliability

Months later, these Monster slings have become a staple in my gear closet, migrating from the climbing rack to the garage and even finding a place in my travel bag. They’ve been used for everything from extending anchors on multi-pitch routes to creating temporary rigging solutions for photography equipment. The Metolius Monster 11mm Open Loop Sling has consistently held up to this varied abuse.

The 11 mm Dyneema construction has proven remarkably resilient. I’ve deliberately subjected them to some abrasion against rough rock faces and even a concrete workshop floor (accidentally, I might add), and they’ve emerged without any significant degradation. This is a stark contrast to some older, thinner slings I’ve owned which would show visible fuzzing after similar incidents. Maintaining these slings is as simple as can be; a rinse in fresh water after salty adventures or a quick scrub with mild soap for workshop grime is all that’s typically required. They dry quickly, a benefit of the Dyneema material, and store compactly.

Specifications

The Metolius Monster 11mm Open Loop Sling is constructed from Dyneema, a material renowned for its exceptional strength-to-weight ratio and resistance to abrasion and UV degradation. This choice of material directly contributes to the sling’s impressive 22 kN breaking strength, a critical safety factor for any climbing or rigging application. The 11 mm diameter offers a good balance; it’s wide enough to be comfortable to handle and resistant to cutting from sharp edges, yet not so bulky as to add unnecessary weight or become unwieldy.

Each sling weighs in at a mere 0.3 oz, making it incredibly lightweight, especially when you consider the strength it offers. This minimal weight is a significant advantage for alpine climbing or any scenario where ounces matter. The sling is presented as an open loop, meaning it’s a continuous loop of webbing, a simple yet effective design that eliminates potential failure points associated with sewn knots. This CE/UIAA certified product meets rigorous international safety standards, providing peace of mind for its intended uses.

Performance & Functionality

At its core, the Metolius Monster 11mm Open Loop Sling excels at its primary function: providing a strong, reliable loop for various applications. In climbing, this translates to dependable anchor extensions, comfortable quickdraw configurations, and secure elements in haul systems. The Dyneema webbing offers a smooth glide through carabiners, minimizing wear on both the sling and the metal, and its inherent stiffness prevents it from collapsing into an inconvenient knot when not under load.

A significant strength is its versatility; it performs admirably in both its intended climbing roles and in broader utility contexts like workshop organization or temporary rigging. While it’s not designed for tasks requiring extreme flexibility or cushioning, its robustness is undeniable. Its performance is, quite simply, exactly what you’d expect from a high-quality Dyneema sling – strong, durable, and reliable.

Design & Ergonomics

The design of the Metolius Monster 11mm Open Loop Sling is elegantly simple, focusing on functional efficacy. The 11 mm width makes it easy to grip, even with gloves on, and provides a reassuring feel of solidity. The open loop design is clean and free of sewn stitches, which can sometimes be a failure point in other slings.

The material itself, Dyneema, has a unique tactile quality – it’s smooth yet has a slight grippy texture that prevents it from slipping unexpectedly. This contributes to its overall user-friendliness, as it behaves predictably under various conditions. There’s no real learning curve here; it’s a sling, and it functions as a sling should, albeit with a high degree of quality and reliability.

Durability & Maintenance

Durability is where the Metolius Monster 11mm Open Loop Sling truly shines, largely due to its Dyneema construction. For its intended use in climbing and mountaineering, these slings are built to last for many seasons, provided they are inspected regularly and retired if signs of significant wear or damage occur. The material’s resistance to UV rays also means it won’t degrade as quickly when exposed to sunlight during prolonged outdoor use.

Maintenance is refreshingly straightforward. A simple rinse with clean water is often sufficient to remove dirt and grime. For more stubborn debris, a mild soap and gentle scrub can be employed, followed by thorough rinsing. It’s crucial to allow the sling to air dry completely in a shaded area, away from direct heat, before storing it. While incredibly strong, Dyneema can be susceptible to damage from sharp edges, so always inspect the sling for nicks or cuts.

Accessories and Customization Options

The Metolius Monster 11mm Open Loop Sling is, by design, a minimalist piece of equipment. It comes as a singular item, an open loop sling, and is not typically sold with accompanying accessories. Its strength lies in its simplicity and its integration with other climbing hardware like carabiners, anchors, and harnesses.

There are no inherent customization options for the sling itself, but its true “customization” comes from how you choose to employ it within your overall gear system. For example, one might choose to color-code these slings for different lengths or purposes within their rack, although they are often sold in assorted colors. Their compatibility with standard climbing carabiners is, of course, universal.

Pros and Cons of Metolius Monster 11mm Open Loop Sling

The Metolius Monster 11mm Open Loop Sling is an excellent choice for a wide range of individuals who require reliable, strong, and lightweight cordage. Climbers, especially those involved in aid climbing, multi-pitch ascents, or building anchors, will find these indispensable.
