Metolius 13mm Monster Open Loop Sling Review

The Metolius 13mm Monster Open Loop Sling: Is It Really That Good?

For years, I’ve relied on a variety of slings for different tasks, from setting anchors in the alpine to extending gear loops in the workshop. My need for a lightweight yet bomber sling for quick draws and extending placements led me to the Metolius 13mm Monster Open Loop Sling. I was looking for something that wouldn’t add bulk to my rack but could still handle the rigors of varied use.

My decision to try this particular sling stemmed from a persistent need for reliable, no-frills extensions. I’d experienced some issues with thicker, heavier materials snagging or feeling cumbersome on longer routes, so a 13mm Dyneema option seemed like a good compromise. My first impression upon holding it was its surprising lightness and the smooth, yet grippy feel of the webbing.

I had briefly considered some ultra-light, thinner Dyneema slings from other brands, but their potential for abrasion concerns gave me pause. Ultimately, the reputation of Metolius for quality climbing hardware tipped the scales. My initial reaction was one of quiet confidence; it felt like a tool built for purpose, without unnecessary embellishments.

Real-World Testing: Putting Metolius 13mm Monster Open Loop Sling to the Test

My testing ground for this Metolius sling was primarily within the climbing realm, specifically on multi-pitch routes in moderate alpine conditions and for extended gym sessions. I used it in scenarios where extending a piece of protection or creating a more optimal clipping point was crucial. The sling was subjected to repeated clipping and unclipping, occasional drags over rock, and the general stresses of load-bearing.

It performed admirably in various conditions, from dry desert rock to damp mountain air. Its 13mm Dyneema Monster Sling webbing proved to be resistant to the minimal moisture it encountered, and it maintained its integrity without becoming stiff or unwieldy. The ease of use was immediately apparent; it’s a simple, open-ended sling, so there was no learning curve.

One minor surprise was how well the material shed dirt and grime after a particularly dusty approach; it cleaned up with a quick brush. I experienced no issues with fraying or any signs of degradation, even after significant use.

Extended Use & Reliability

After several months of consistent use, the Metolius 13mm Monster Open Loop Sling has become a staple on my climbing rack. It has seen extensive use on granite, limestone, and in a gym setting, and it continues to perform without complaint. I’ve used it for everything from extending ice screws to creating redundant anchor points.

The durability has been impressive. Despite being dragged over rough rock and subjected to numerous loadings, there are no visible signs of wear, such as thinning, fraying, or stiffness. Its consistent performance is a testament to the quality of the Dyneema.

Maintenance is virtually non-existent. A quick wipe with a damp cloth is usually all that’s needed, and it dries rapidly. I haven’t needed to perform any deep cleaning or special treatments. Compared to older nylon slings I’ve used, which would become stiff and absorb water, this Dyneema sling offers superior longevity and performance in varied conditions.

Breaking Down the Features of Metolius 13mm Monster Open Loop Sling

Specifications

The Metolius 13mm Monster Open Loop Sling is built with a 13mm Dyneema Monster Sling webbing, offering a balance of strength and a manageable width. It comes in a standard 22-inch length, which is a versatile size for a multitude of applications, from creating a quickdraw extender to setting up anchors.

Weighing in at a mere 0.5 oz, this sling is incredibly lightweight, making it an ideal choice for alpine climbing or any situation where minimizing pack weight is paramount. Its breaking strength is rated at 22 kN, which is more than sufficient for the demands placed upon it in climbing and mountaineering. The fact that it is CE/UIAA certified provides additional peace of mind regarding its safety and quality.

The assorted color option means you might receive any of a range of colors, which can be a minor drawback if you prefer color-coded gear for quick identification, but it doesn’t impact functionality. This sling’s simple, open-loop design eliminates the need for knot tying, simplifying its use in dynamic situations and ensuring a consistent length without adjustment.

Performance & Functionality

The primary job of the Metolius 13mm Monster Open Loop Sling is to provide a strong, lightweight, and reliable extension or connection point, and it excels at this. Its main function is to act as a versatile sling that can be used in various configurations, such as a quickdraw extender or an anchor component. The 13mm width strikes a good balance, offering a noticeable surface for handling and clipping without the bulk of wider slings.

Its strength lies in its simplicity and the inherent properties of Dyneema. It handles loads smoothly and consistently, and the open-loop design means it can be quickly incorporated into a system. The only minor weakness, if one could call it that, is the lack of color options for immediate gear differentiation, but this is a small trade-off for its overall efficacy.

This sling unequivocally meets and exceeds expectations for its intended purpose. It’s a no-nonsense piece of gear that performs exactly as advertised, providing a secure and lightweight solution for common climbing needs.

Design & Ergonomics

The design of the Metolius 13mm Monster Open Loop Sling is elegantly straightforward. Its build quality is evident in the tightly woven Dyneema Monster Sling webbing, which feels robust yet pliable. The finish is smooth, with no rough edges or imperfections that could cause concern.

Ergonomically, it’s designed for quick and easy manipulation. The 22-inch length allows for comfortable reach and extension without being so long that it becomes a hindrance. The open loop design means it can be readily attached to carabiners or gear loops, and its moderate width provides a decent grip, even with gloves on.

There are no complex controls or markings to worry about; its utility is derived solely from its material strength and design. The simple, effective nature of the design means there’s virtually no learning curve, making it accessible to climbers of all experience levels.

Durability & Maintenance

Under typical climbing use, the Metolius 13mm Monster Open Loop Sling is designed for long-term durability. Dyneema webbing is inherently resistant to UV degradation and abrasion, suggesting it will maintain its strength and integrity for many years. I anticipate it will easily outlast many of my other climbing accessories.

Maintenance is incredibly minimal. A simple rinse with water to remove dirt or chalk is all that is typically required, and it dries quickly due to the nature of the synthetic material. There are no specific maintenance tips beyond avoiding prolonged exposure to open flame or excessive heat, which is standard for synthetic materials.

One potential point of concern with any sling is extreme abrasion from sharp rock edges. While the 13mm Dyneema is robust, users should always inspect slings for damage before each use, particularly after a rough drag or scrape. However, in my experience, this sling has shown remarkable resilience to such scenarios.

Accessories and Customization Options

The Metolius 13mm Monster Open Loop Sling comes as a singular unit, with no specific accessories included. Its beauty lies in its simplicity, meaning it’s designed to be integrated with your existing climbing hardware rather than requiring additional components.

Customization is essentially non-existent beyond its integration into a climbing system. It is designed to work seamlessly with carabiners, harnesses, and other protection devices. There are no user-replaceable parts or aftermarket modifications that would enhance its core function.

Its compatibility with standard climbing gear is universal, so any carabiner or quickdraw component will work effectively with it. The focus is on its inherent strength and usability as a standalone piece of essential equipment.

Pros and Cons of Metolius 13mm Monster Open Loop Sling

Who Should Buy Metolius 13mm Monster Open Loop Sling?

This sling is an excellent choice for any climber, particularly those focused on alpine routes, multi-pitch climbs, or any activity where minimizing weight is a priority. It’s also a great addition for general rock climbers looking for a reliable, lightweight extension for their gear. The 13mm width makes it easy to handle and clip, even with gloves on.
