Ever stood at the base of a climbing route, heart racing with anticipation, only to realize you’re not sure if your gear is right for the challenge? That moment of doubt can shake even the most eager beginner. Let’s banish that uncertainty forever.
Climbing slings are deceptively simple yet critically important pieces of equipment in your climbing arsenal. These loops of webbing or cord serve as crucial connectors in your safety system, creating anchor points, extending protection, and even saving your life in emergency situations. They’re not just accessories—they’re essential lifelines between you and the rock face.
The language of loops
When you step into the climbing world, you’ll encounter various terms for these versatile tools:
- Runners: Single loops of webbing
- Slings: The general term for any loop (nylon, Dyneema, or hybrid materials)
- Quickdraws: Pre-assembled combinations of two carabiners connected by a short sling
- Alpine draws: Longer, more versatile slings that can be shortened as needed
Each type serves specific purposes, from the ultralight Dyneema slings that minimize weight on multi-pitch routes to the more abrasion-resistant nylon options perfect for rugged terrain.
Why your choice matters
For beginners, selecting appropriate slings isn’t just about gear—it’s about building confidence. The right slings match your climbing style and environment while providing the safety margin you need while developing skills. Proper selection creates mental space for focusing on technique rather than worrying about equipment failure.
Remember: your climbing system is only as strong as its weakest link. Choose wisely, climb boldly.
Material Matters: Choosing the Right Climbing Slings
When you’re hanging off a rock face 100 feet up, the last thing you want to worry about is whether your gear can handle the job. Climbing slings might look like simple loops of fabric, but they’re sophisticated pieces of safety equipment engineered to save your life when it matters most.
For beginners navigating the world of climbing gear, understanding how to choose climbing slings for beginners starts with knowing what they’re made of and how they’re constructed. This seemingly small piece of equipment plays a crucial role in your safety system, connecting you to protection points and helping manage rope drag during your ascent.
Nylon vs. Dyneema: The Material Showdown
The climbing world primarily offers two materials for slings, each with distinct personalities:
Nylon Slings bring the stretch factor to the party. With approximately 20-30% dynamic elongation under load, these workhorses absorb energy during falls, potentially reducing impact force on your protection points.
Nylon Strengths:
- More affordable ($5-10 per sling)
- Better shock absorption
- Greater durability against abrasion
- Performs reliably when wet (only loses about 10-15% strength)
- Handles knots beautifully
Nylon Weaknesses:
- Heavier (about 30% more than Dyneema)
- Absorbs water (becoming heavier)
- Degrades from UV exposure over time
Dyneema/Spectra Slings represent the lightweight champions. These ultra-high-molecular-weight polyethylene fibers offer minimal stretch (less than 5%) with incredible strength-to-weight ratios.
Dyneema Strengths:
- Incredibly lightweight
- Higher strength-to-weight ratio
- Water resistant
- Less UV degradation than nylon
Dyneema Weaknesses:
- More expensive ($8-15 per sling)
- Almost no dynamic elongation (potentially higher impact forces)
- Lower melting point (can be damaged by friction heat)
- Performs poorly with knots (can reduce strength by up to 60%)
Pro Tip: For beginners building their first rack, start with a mix of both materials. Use nylon for anchor building and Dyneema for extending protection where weight matters.
Width, Strength, and Standards
When examining slings, you’ll notice variations in width and corresponding strength ratings:
| Width | Typical Material | Average Breaking Strength | Common Uses |
|---|---|---|---|
| 10mm | Nylon | 22kN | Anchors, traditional climbing |
| 12mm | Nylon | 25kN | Heavy-duty anchors |
| 8mm | Dyneema | 22kN | Sport climbing, alpine |
| 10mm | Dyneema | 24kN | Multi-purpose |
All climbing slings must meet certification standards from organizations like the UIAA (International Climbing and Mountaineering Federation) or CE (European Conformity). These certifications ensure minimum breaking strengths of at least 22kN (approximately 4,945 lbs of force).
Always check for certification tags sewn into the sling—they’re your assurance that the equipment has been tested to withstand climbing forces.
Sewn vs. Tied: A Safety Decision
For beginners, the choice between sewn slings and tied slings is straightforward: choose sewn slings.
Sewn slings from manufacturers like Black Diamond or Petzl offer consistent strength, factory-tested reliability, and eliminate user error. The bar-tacked connection point is typically stronger than any knot you could tie yourself.
Tied slings require expert knowledge of appropriate knots (typically the water knot) and regular inspection. Even perfectly tied knots can reduce a sling’s strength by 30-50%, and they can work loose over time without proper maintenance.
Remember that your climbing system is only as strong as its weakest link. For beginners still mastering the fundamentals, sewn slings provide one less variable to worry about while you focus on developing your climbing skills.

Extending your slings’ lifespan
Your climbing slings aren’t just gear—they’re life insurance policies. Treat them accordingly with these maintenance essentials:
Post-climb ritual: After each outing, shake out dirt and inspect for damage. For nylon slings, gentle hand washing with mild soap removes chalk and sweat that can degrade fibers over time. Dyneema slings can be rinsed with clean water—avoid detergents as they can compromise the material.
Storage wisdom: Store slings loosely coiled in a cool, dry place away from direct sunlight. UV exposure is kryptonite for climbing textiles, potentially reducing strength by up to 30% before visible signs appear.
The most dangerous sling isn’t the one that breaks dramatically—it’s the one that looks fine but has been silently compromised by improper care.
Inspection discipline: Develop a monthly deep inspection habit. Run slings slowly through your fingers, feeling for inconsistencies in thickness, checking stitching for fraying, and examining for discoloration that might indicate chemical exposure.
When to retire your trusted companions
Even the finest slings have an expiration date. Knowing when to say goodbye could save your life:
The five-year rule: Regardless of visible condition, most manufacturers recommend retiring slings after five years from first use. This isn’t marketing—it’s science. Microscopic degradation occurs even in perfectly stored equipment.
Immediate retirement triggers include:
- Visible core fibers (white strands peeking through colored sheath)
- Burns or glazed areas from rope friction
- Cuts, tears, or significant abrasion
- Exposure to chemicals, including some climbing chalk brands with drying agents
- Any fall that generates forces approaching a sling’s rating
Documentation discipline: Mark purchase dates on slings with tape at the ends, or maintain a gear log. When in doubt about a sling’s history or condition, remember the climber’s mantra: If you’re questioning it, replace it. The $15 you save isn’t worth the risk when you’re 80 feet up with exposure below.
By selecting quality slings appropriate for your budget, maintaining them meticulously, and retiring them before they become liabilities, you’re not just buying gear—you’re investing in the confidence to push your climbing to new heights, safely.
