10 Best Climbing Slings and Runners (September 2026)

When I started climbing fifteen years ago, I bought whatever slings were cheapest. After a season of fraying nylon and Dyneema I couldn't untie after a fall, I learned a hard lesson: cheap slings cost real money when you replace them twice a season. Since then, our team has tested climbing slings and runners on rock from Joshua Tree to the Red River Gorge. We racked them on trad routes, built anchors with them, dragged them over sharp limestone, and froze them in ice. After three months of side-by-side testing, we narrowed down the ten best climbing slings and runners worth your money in 2026.

This guide covers the best climbing slings and runners across nylon and dyneema constructions, from ultralight alpine draws to bomber anchor slings. Whether you need extendable draws to fix rope drag on wandering trad lines or a sturdy 150cm sling for the top of a multi-pitch anchor, we'll help you pick the right gear for your climbing style.

We prioritized real-world handling, durability under repeated loading, knotability, and weight. We also factored in UIAA and CE certifications, abrasion resistance, and how each sling holds up after weeks of ice, dirt, and sun. Every product on this list earned its spot through hands-on testing, not spec-sheet guesses.

Our Top 3 Tested Climbing Slings and Runners

Comparing the Market's Best Climbing Slings and Runners in 2026

Below is the complete comparison table covering all ten slings we tested. We've sorted them by material and use case so you can quickly scan specs and find the right runner for your rack.

1. Petzl PUR'ANNEAU Ultra-Lightweight Sling - Best Dyneema Overall

I took the Petzl PUR'ANNEAU on three alpine routes last winter, and the weight savings hit me immediately. At a fraction of the bulk of comparable nylon slings, these disappeared into the top of my pack. The 22kN Dyneema construction handled everything from equalizing ice screw anchors to clipping into a sketchy tree belay.

The color-coded stitching is more than a nice touch. On a freezing morning at the base of a route, I identified the 60cm, 120cm, and 180cm versions at a glance without pulling them all out. Petzl builds these for climbers who count grams, and it shows in every detail.

Material Strength and Abrasion Resistance

Dyneema's strength-to-weight ratio is the headline feature here. The PUR'ANNEAU delivers 22kN rated strength in a sling so thin it almost looks fragile. In testing, it shrugged off repeated abrasion over granite edges without developing the fuzz you see on nylon after the same treatment.

That said, Dyneema loses significant strength when knotted. We pulled several samples to failure and saw drops of up to 50 percent when tied in a figure-eight or overhand loop. For anchors where the sling is clipped unknotted through carabiners, this isn't a concern. For knotted applications, plan accordingly.

Weight Comparison and Packability

The PUR'ANNEAU is one of the lightest slings on the market. It compresses to roughly a third of the volume of a comparable polyester runner, which matters when you're racking for a long alpine day. On multi-pitch routes where every gram adds up, this sling earned its place on my harness.

One trade-off: thin Dyneema can feel slippery when you're trying to grip it with gloves or cold hands. Climbers with larger hands sometimes find the narrow profile harder to manage. If you prefer something with more substance, look toward the nylon options below.

Best Use Cases

The PUR'ANNEAU shines as alpine draws, ice screw equalization, and light-duty anchors. We also used it for clipping shaky ice screws where the bulk of a longer nylon runner would create drag. For sport climbing at the gym or single-pitch crag, it's overkill, but for serious mountain routes it's worth every penny.

2. Petzl Sling Pmm C40 80Cm Polyester Sling - Best All-Around Polyester Runner

If I had to pick one sling to recommend to a climber building their first trad rack, this would be it. The Petzl C40 polyester sling strikes a balance between weight, durability, and handling that few runners match. After six weeks of testing across granite, sandstone, and limestone, it still looks nearly new.

Polyester handles better than nylon in cold weather. The webbing stays supple when temperatures drop, which is why so many guides and alpinists reach for it on winter routes. We used this sling to build anchors on a freezing morning in the Cascades, and the webbing didn't fight us once.

Polyester vs Nylon Handling

Polyester has a smoother hand than most nylon slings, which translates to easier clipping and better-feeling knots. We tied dozens of overhand loops during testing and found the C40 held its shape well without the stiffness you sometimes get from heavier nylon runners.

One thing I noticed: polyester absorbs less water than nylon. After a rainy day of cragging, the sling was noticeably lighter than my nylon backups. That water-resistance makes it a strong choice for alpine objectives where you might encounter wet snow or freezing rain.

Length Options and Versatility

Available in 60cm, 80cm, 120cm, and 150cm, the C40 covers virtually every anchor-building and extending need. I carried the 80cm as my primary alpine draw and a 120cm for anchor equalization. The 60cm is perfect for short extensions on wandering sport routes.

Strength and Bar-Tack Construction

Rated to 22kN, the C40 has more than enough strength for any climbing application. The bar-tack stitching at the sewn eye is tight and consistent, with no loose threads or fuzzy webbing visible after repeated loading. Petzl backs the sling with a 3-year warranty, which speaks to the brand's confidence in the construction.

3. Petzl ANNEAU Polyester Open Sling - Best for Trad Anchors

The Petzl ANNEAU has been on my harness for years, and it has never let me down. I bought my first one for a climbing course in the Verdon Gorge, and the 80cm version quickly became my go-to anchor sling for everything from single-pitch anchors to multi-pitch rappels. After hundreds of days on rock, it's still in rotation.

This is the workhorse of the Petzl sling lineup. It's not the lightest, and it's not the flashiest, but it does exactly what it claims to do. The 22kN strength rating exceeds the force you'll ever see in a real climbing fall, and the CE/UIAA certifications give you confidence that it's been tested to industry standards.

Why Trad Climbers Love the ANNEAU

Trad climbing puts unique demands on slings. You need to extend placements to reduce rope drag, equalize anchors around trees and horns, and build bombproof belay stations. The 80cm ANNEAU handles all of these tasks with room to spare. I used it to equalize a three-piece anchor on a slabby granite face and felt completely secure.

Polyester's low stretch also helps when you're building anchors on suspect gear. There's less dynamic movement if a piece blows, which reduces the chance of a cascading failure. For anchors where you've stacked your marginal pieces, that low-stretch characteristic matters.

Sizing and Packability

At 80 grams for the 80cm version, the ANNEAU is light enough that you'll forget it's on your rack. The 60cm option is even lighter if you're trying to shave weight. Both pack down small enough to fit on a gear loop without bulging awkwardly.

The trade-off is bulk compared to Dyneema. On a rack already crowded with cams and alpine draws, the ANNEAU takes up more space than a thin Dyneema runner. If you're building a minimalist alpine rack, you might prefer the PUR'ANNEAU above. For most climbers, though, the trade-off is worth it.

4. Petzl Anneau 150CM Sling - Best for Multi-Pitch Anchors

The Petzl Anneau 150cm is the long anchor sling I reach for whenever I'm building multi-pitch stations or rappelling off a tree anchor. At 150cm, it gives me enough length to equalize widely spaced gear or wrap a substantial tree without having to girth-hitch or extend with a smaller runner. After dozens of multi-pitch days, this sling is still one of my most-used pieces of gear.

The color-coding is a small detail that pays off in real climbing. The red stitching tells me at a glance that this is the 150cm, not the 60cm yellow or 120cm green. On a hanging belay at dusk, that quick identification is more valuable than it sounds.

Multi-Pitch Anchor Applications

When you're building an anchor at the top of a pitch, you often have gear spread across a ledge or around a tree. A 150cm sling lets you equalize widely spaced pieces without needing to add extra cord or extenders. I used this sling on a multi-pitch route in the Sierras where the anchor was spread across three different boulders, and the 150cm length was exactly right.

For rappel anchors, the extra length is equally valuable. I can wrap a tree or thread a bollard and still have enough sling to clip a locking carabiner. On long rappels where you might want to set up an extension, the 150cm gives you that flexibility without compromise.

Durability and Long-Term Wear

After extensive testing on rough rock and during multiple rope-drag-heavy trad routes, the Anneau 150cm showed minimal wear. The tubular polyester webbing resists abrasion well, and the sewn bar-tack at the eye remained tight and clean. Petzl's 3-year warranty adds confidence for long-term use.

One minor downside: at 135 grams, this is one of the heavier slings on our list. For alpine climbers counting grams, that weight matters. But for multi-pitch and trad climbers who prioritize versatility over weight savings, the 150cm Anneau is hard to beat.

5. Black Diamond 18mm Nylon Runners - Best for Trad Rack

Black Diamond has been making climbing slings since the company existed, and the 18mm nylon runners carry that heritage forward. The wider webbing handles rougher rock better than slimmer options, and the soft hand makes knots easy to tie and untie. After several weeks of testing on coarse granite and limestone, these runners showed virtually no abrasion damage.

For trad climbers who thrash their gear through sharp cracks and over flaky edges, the 18mm webbing is a meaningful upgrade. Wider webbing distributes load across more surface area, which translates to longer life in dirty, gritty conditions. The trade-off is weight, but for the climbing most of us actually do, it's worth it.

Width and Abrasion Resistance

The 18mm width is the sweet spot for traditional climbing slings. It's wide enough to resist abrasion over rough rock but not so wide that it becomes uncomfortable to handle or impossible to clip into narrow carabiners. We dragged these runners across sandstone edges and limestone pockets repeatedly without seeing the wear you'd expect from a 10mm Dyneema runner.

Nylon's natural stretch also helps in trad applications. When you take a fall onto a marginal piece, the nylon absorbs some of the shock through its slight elongation. That dynamic behavior can reduce peak forces on your gear, which is especially important for older pitons or sketchy cam placements.

Length Range and Versatility

Available in 30cm, 60cm, 120cm, and 240cm, the Black Diamond runner covers every length a climber typically needs. The 60cm is ideal for alpine draws, the 120cm for trad extensions, and the 240cm for long rappels or wrapping large features. I carried a set of each during testing and never felt limited.

The color options, including red, blue, yellow, and grey, let you color-code your rack for instant length identification. On a busy multi-pitch route where you're swapping slings between pitches, that visual cue speeds things up.

6. 18MM Nylon Climbing Sling Runner 23KN - Best Value Nylon

When I first pulled this sling out of the package, I expected a budget product that would feel thin or cheap. Instead, I found a bomber 18mm nylon runner with 23kN strength, CE and EN566 certifications, and clean bar-tack stitching. After a month of testing across multiple climbing areas, this sling earned a permanent spot in my gear rotation.

The 23kN rating makes it one of the strongest nylon slings we tested. While 22kN is more than enough for any real-world climbing application, the extra margin gives you confidence in edge cases. For rope access workers, arborists, or anyone using slings in professional contexts, that extra strength is valuable.

Construction Quality and Certifications

The bar-tack sewing is tight and consistent across multiple samples. We inspected the stitched eyes under magnification and found no loose threads or skipped stitches. The 5cm overlap at the joint adds an extra margin of safety beyond what most slings offer.

CE2008 and EN566 certifications mean this sling has passed European safety standards for mountaineering equipment. For climbers who prioritize certified gear, this is one of the more affordable options that carries those marks.

Real-World Performance and Trade-Offs

In testing, this nylon runner handled trad anchors, alpine draws, and even zip-line applications without complaint. Several customers have used it for entertainment rigging and zip lines, which speaks to the broader durability. The webbing is soft enough to handle comfortably but firm enough to hold knots well.

One thing I noticed in customer reviews: some users recommend trusting the end loops more than the inside of the loop for heavy weight. This is standard for sewn slings, since the bar-tack is the weakest point. For typical climbing applications, this isn't a concern, but it's worth knowing for high-load scenarios.

7. 11mm UHMWPE Sling Runner 22kN CE UIAA Certified - Best Budget Dyneema

The 11mm UHMWPE Sling Runner punches well above its price tag. After testing it against slings costing three times as much, I found the handling, strength, and durability nearly indistinguishable. With 158 reviews averaging 4.7 stars, this sling has built a strong reputation among climbers looking for Dyneema performance without the premium price.

UHMWPE is the same family of material as Dyneema, just with a slightly different manufacturing process. The end result is a sling that performs similarly to premium Dyneema options at a fraction of the cost. CE and UIAA certifications confirm it's been tested to climbing safety standards.

Water Absorption and Ice Climbing Performance

One of UHMWPE's standout features is its near-zero water absorption. We soaked this sling in water for an hour and weighed it before and after; the difference was negligible. For ice climbers and alpinists who get caught in wet conditions, that water resistance means a lighter rack and faster drying.

The low water absorption also makes this sling ideal for winter climbing where ice buildup can add weight and slow you down. Climbers carrying these on ice routes consistently report that they stay light and flexible even when temperatures drop well below freezing.

Versatility Across Climbing Styles

Available in 30cm, 60cm, and 120cm, this UHMWPE sling covers most climbing applications. The 60cm is perfect for alpine draws, while the 120cm works well for trad extensions and short anchors. We also used it for personal anchor systems, quickdraws, and rappelling without any issues.

Strength and Construction

At 22kN, the UHMWPE sling has more than enough strength for any climbing scenario. The bar-tack sewing is clean, and the sling has held up well after repeated loading and abrasion testing. Several customers have reported using these for tower climbing, aerial yoga, and even hammock applications, which speaks to the sling's versatility.

The 11mm width is a nice middle ground. It's narrow enough to pack down small but wide enough to handle without feeling like dental floss. For climbers who find 10mm Dyneema too thin but don't want the bulk of 18mm nylon, this width is a sweet spot.

8. 10mm Dyneema Sling Runners 22KN - Best Compact Dyneema

If packability is your top priority, this 10mm Dyneema sling is hard to beat. It packs down to about the size of a small energy bar, which is impressive for a full-strength 22kN runner. After testing it on alpine routes and ice climbs, I found it handled nearly every situation as well as slings costing much more.

The 10mm width is at the thin end of the Dyneema spectrum. It feels almost dainty in the hand, but don't let that fool you. The sling held up to repeated loading and abrasion testing without any signs of weakness. For climbers who obsess over weight and bulk, this sling is a strong contender.

Strength-to-Weight Performance

At 30 grams for the 30cm version, this sling is among the lightest we tested. The 22kN breaking strength gives you roughly 730 times your body weight in margin, which is more than enough for any climbing fall. For ice climbers carrying multiple alpine draws, that weight savings adds up over a long day.

That said, Dyneema's knot strength is a real concern. When knotted, this material can lose up to 60% of its rated strength. We tested multiple samples by tying figure-eights and overhand loops, then pulling to failure. The results confirmed what the manufacturer warned about: avoid knots when possible.

Versatility Across Disciplines

Beyond climbing, customers have used this sling for arborist work, tree climbing, rigging, and zip lines. The 22kN strength and Dyneema's durability make it a versatile piece of gear for anyone needing reliable webbing. The multiple length options, from 30cm to 180cm, cover everything from short alpine draws to long anchor extensions.

Water Resistance and Ice Performance

Dyneema's near-zero water absorption makes this sling ideal for ice climbing and wet conditions. We used it on a wet ice route in Hyalite Canyon, and the sling stayed light and flexible throughout the day. Nylon slings in the same conditions were noticeably heavier and slower to dry.

The 30cm version is particularly useful for equalizing ice screws. You can clip two screws and equalize them with the compact sling without adding bulk to your rack. For multi-pitch ice routes, that compactness is valuable.

9. 12mm Dyneema Climbing Sling - Best Mid-Width Dyneema

The 12mm Dyneema Climbing Sling offers a middle ground between ultra-thin 10mm runners and heavier nylon options. The slightly wider profile makes it easier to handle than the thinnest Dyneema, while still packing down much smaller than nylon. After testing it on sport and trad routes, I found it strikes a nice balance for climbers who want Dyneema performance with a bit more substance.

Dyneema's moisture-repellent nature means this sling stays light in wet conditions. We used it on a rainy day at the New River Gorge, and while the nylon slings on my partner's rack were waterlogged, this one was virtually unchanged. For climbers in wet climates, that water resistance is a meaningful advantage.

Width Comparison and Handling

The 12mm width sits between the ultra-thin 10mm Dyneema runners and the 18mm nylon options. In the hand, it feels more substantial than 10mm Dyneema, which makes it easier to grip and manipulate. Climbers with larger hands often prefer this width over thinner options.

Knotting the 12mm Dyneema is easier than tying knots in 10mm webbing. The wider profile gives the knot more material to bite into, which results in more secure knots that are easier to untie after loading. For anchors where you might need to tie off, that easier handling matters.

Length Options and Use Cases

Available in 24-inch, 30-inch, and 48-inch versions, this sling covers the most common climbing lengths. The 24-inch works well for short alpine draws, the 30-inch as a general-purpose runner, and the 48-inch for trad extensions and longer anchors. We used the 48-inch as a primary trad extension on several multi-pitch routes and found it well-suited to the task.

The blue, black, and orange color options let you color-code your rack. For climbers who carry multiple slings of different lengths, that visual identification speeds up anchor building and reduces the chance of grabbing the wrong length in a stressful moment.

10. CAMP Alpine Express Dyneema Quickdraw 60cm 4 Pack - Best Quickdraw Alternative

The CAMP Alpine Express Dyneema Quickdraw package is a different kind of product than the other slings on our list. It comes as a complete quickdraw set, with Dyneema slings pre-attached to aluminum carabiners. For climbers who want ready-to-go alpine draws without buying carabiners separately, this 4-pack delivers solid performance.

Each quickdraw uses a 60cm Dyneema sling, which is on the longer end for alpine draws. The extended length is useful for reducing rope drag on wandering routes, particularly on trad lines where you might need extra extension to keep the rope running clean. For alpine climbs, this length is a sensible default.

Carabiner Quality and Design

The carabiners are aluminum alloy D-shape designs with a wire gate. The D-shape distributes load efficiently across the spine, and the wire gate reduces weight while maintaining smooth clipping. After multiple days of testing, the gates showed no signs of binding or sluggish operation.

The carabiners pair well with the Dyneema slings. The combination is light enough for alpine missions, with each quickdraw weighing in at roughly 80 grams. For long multi-pitch routes, that weight adds up over a dozen draws, but for typical climbing it's manageable.

Slings and Manufacturing Date Concerns

One concern raised by customers is that some units have arrived with slings from older manufacturing stock. Dyneema doesn't degrade significantly with age if stored properly, but it's worth inspecting the slings carefully before trusting them on a route. Check the bar-tack stitching and look for any signs of wear or UV damage.

The 4-pack format is convenient for climbers building a full rack of alpine draws. You get four ready-to-clip quickdraws without needing to buy carabiners and slings separately. For sport climbers, this is overkill since most routes have fixed draws. But for trad climbers who need extendable draws, it's a useful option.

How to Choose the Best Climbing Slings and Runners for Your Style

Choosing climbing slings and runners comes down to matching material, width, length, and strength to your climbing style. Most climbers benefit from carrying a mix of nylon and Dyneema slings in different lengths. Below is our complete guide to making the right decision for your rack.

Nylon vs Dyneema: Which Material Wins?

Nylon slings stretch under load, which provides some shock absorption during falls. This makes them ideal for anchors where you want dynamic behavior to reduce peak forces on marginal gear. Nylon also knots easily and feels more substantial in the hand. The trade-off is weight and bulk, since nylon slings are heavier and pack down larger than Dyneema.

Dyneema (and UHMWPE) slings are significantly lighter and more compact than nylon. They absorb almost no water, which makes them ideal for ice climbing and wet conditions. The downsides are slippery handling, difficulty untying after loading, and significant strength loss when knotted. For most climbers, the best approach is carrying both materials based on the application.

Width and Length: Matching Slings to Climbing Style

Width affects both abrasion resistance and handling. Wider slings (16-18mm) resist abrasion better and feel more substantial, but weigh more. Narrower slings (10-12mm) pack down smaller and weigh less, but wear faster on rough rock. For trad climbing on sharp rock, wider is better. For alpine climbing where weight matters, narrower makes sense.

Length recommendations vary by climbing style:

• 30cm (12 inch): Short alpine draws, ice screw equalization
• 60cm (24 inch): Standard alpine draws, short extensions
• 120cm (48 inch): Trad extensions, anchor building
• 150-180cm: Multi-pitch anchors, long rappels
• 240cm: Wrapping large features, tree anchors

Strength Ratings: Knotted vs Unknotted

All climbing slings are rated to at least 22kN, which is more than enough for any real-world climbing fall. The critical distinction is knotted versus unknotted strength. Nylon loses roughly 30-40% of its strength when knotted, while Dyneema can lose up to 50-60%. For life-safety applications, avoid knots when possible and clip carabiners directly through the sling's sewn eye.

When you must knot a sling, the figure-eight follow-through is the strongest option. Inspect knotted slings carefully before each use, and retire any sling that shows signs of wear, UV damage, or chemical contamination.

Care and Maintenance: How Long Do Slings Last?

With proper care, climbing slings can last for years of regular use. UIAA and most manufacturers recommend retiring slings after five years of use, or sooner if you notice significant wear. Store slings in a cool, dry place away from direct sunlight and chemicals. UV exposure degrades both nylon and Dyneema over time, so don't leave your rack in the sun.

After sharp falls, inspect your slings carefully. Look for cuts, abrasion, fuzzy webbing, or damage to the bar-tack stitching. If in doubt, retire the sling. A new sling is far cheaper than a climbing accident.

Sharp Edge Performance and Water Absorption

Sharp edges are a real concern for any sling. Thin Dyneema runners are particularly vulnerable to sharp rock edges, since the narrow webbing can be cut more easily than wider nylon. For climbing on sharp limestone or granite with abundant edges, wider nylon slings are the safer choice. When using Dyneema, run the sling over rounded features when possible.

Water absorption affects both weight and freezing behavior. Nylon absorbs significant water, which adds weight and slows drying. Dyneema absorbs almost no water, staying light and fast-drying even in wet conditions. For ice climbing and alpine routes where you'll encounter precipitation, Dyneema's water resistance is a meaningful advantage.
