The Backbone of Your Build
Webbing might not get the spotlight like fabric or zippers, but it’s one of the most critical components in outdoor gear, tactical equipment, tie-down systems, pet leashes, and industrial sewing projects. If the webbing fails, the entire product does. That’s why selecting the right webbing material—whether nylon, polypropylene, or cotton—is essential for safety, performance, and longevity.
At Seattle Fabrics, we stock high-quality webbing trusted by manufacturers, small shop fabricators, and serious DIYers. This guide will help you understand how different webbing types perform, what they’re made of, and how to select the right one for your application.
What Is Webbing?
Webbing is a strong, woven fabric strip commonly used in place of rope. It’s designed to hold tension, resist abrasion, and support heavy loads without stretching excessively. You’ll find webbing in:
- Backpack straps
Tactical vests and belts
Tie-down straps and cargo nets
Dog leashes and harnesses
Hammocks and suspension gear
Bag handles and reinforcements
Climbing and rescue equipment (specialized)
Webbing is typically made in flat or tubular styles and comes in various materials, widths, colors, and strengths.
The 3 Main Types of Webbing at Seattle Fabrics
Strength: High tensile strength (often over 4,000 lbs.)
Stretch: Moderate (can absorb shock loads)
Feel: Smooth, flexible, and slightly glossy
Best for: Tactical gear, climbing harnesses, dog leashes, load-bearing straps
Weather resistance: Resistant to abrasion and mildew, but absorbs water and can degrade with prolonged UV exposure
Pro Tip: Nylon is ideal when you need strong, load-bearing straps that can flex under strain. It's commonly used in military applications and rugged outdoor gear.
2. Polypropylene Webbing
Strength: Moderate (usually 600–1000 lbs. depending on width)
Stretch: Low stretch, stays rigid
Feel: Lighter and stiffer than nylon
Best for: Utility straps, water gear, bag handles, tent tie-downs
Weather resistance: Excellent UV, mildew, and moisture resistance
Pro Tip: Polypropylene is a favorite for marine and outdoor settings because it doesn’t absorb water and is budget-friendly. Use it for projects that don’t require extreme strength.
3. Cotton Webbing
Strength: Lower tensile strength compared to synthetic options
Stretch: Minimal stretch
Feel: Soft, natural feel with matte finish
Best for: Casual bags, aprons, vintage-style gear, and accessories
Weather resistance: Poor — prone to mildew and shrinkage if not treated
Pro Tip: Cotton is best used for aesthetic or light-duty applications. While not suitable for load-bearing or wet environments, it offers a natural look and soft texture perfect for fashion or heritage projects.
Flat vs. Tubular Webbing
Flat Webbing is common and offers high tensile strength and a thin profile, great for tight stitching and direct applications.
Tubular Webbing is hollow and more flexible, often used in climbing, rescue gear, and situations where abrasion resistance is critical.
Currently, Seattle Fabrics primarily stocks flat webbing, ideal for sewing into straps and attaching hardware.
Choosing the Right Webbing Width
Webbing comes in widths ranging from 1/2" to 2" or more. To choose the correct width:
Match the width to your hardware (buckles, slides, D-rings)
Use 1" for general-purpose gear and bags
Go 1.5" or 2" for load-bearing or tactical straps
Use narrower widths (5/8" or 3/4") for small accessories or compression straps
Color and Customization
Seattle Fabrics offers webbing in a variety of colors to match your gear, brand, or style. Most webbing types come in black, coyote brown, olive drab, navy, and other functional tones.
Some projects benefit from color coding straps (e.g., for different length tie-downs or ID on tactical packs).
Webbing Accessories and Hardware
Pair your webbing with:
- Side release buckles for quick strap access
Ladder locks for adjustable straps
Triglides to stabilize two-layer webbing paths
D-rings and O-rings for attachment points
Make sure to match hardware width to webbing width for secure and functional straps.
Tips for Sewing Webbing
Use a heavy-duty sewing machine or industrial machine
Choose UV-resistant polyester or bonded nylon thread
Double- or triple-stitch at stress points
Consider reinforcing high-load areas with bar tacks or webbing wraps
Use a hot knife or flame to seal cut ends and prevent fraying
When to Buy in Bulk
If you’re building commercial quantities of tactical gear, straps, pet gear, or packs, buying webbing by the roll will save you money and ensure consistency. Seattle Fabrics offers:
Bulk yardage options
Matching rolls of webbing and hardware
Commercial support for buyers
Contact us for roll pricing or bulk orders if you're outfitting a production run.
