A Consumer’s Guide to Purchasing Narrow Goods for Sewing Projects

When most people start planning a sewing project—whether it’s a custom backpack, a tactical vest, or just replacing a strap on an old duffel bag—they spend hours obsessing over the main fabric. They research the denier of the Cordura, the waterproof rating of the nylon, and the exact shade of Ranger Green. But then, they get to the hardware and straps, and they grab whatever generic spool is cheapest.

This is the rookie mistake that kills great projects. The straps, webbing, Velcro, and binding tape are the skeleton of your gear. They take the tension, the friction, and the abuse. In the industry, these items are collectively known as narrow goods, and understanding how to buy them is the difference between a piece of gear that lasts a lifetime and one that fails on the first trip out.

If you are tired of guessing which webbing to buy, here is your practical guide to navigating the often-confusing world of trims and tapes.

1. Understanding the Webbing Family

Webbing is a catch-all term, but treating all webbing the same is dangerous. The two main materials you will encounter are polypropylene and nylon. They look similar on a screen, but they behave very differently in the wild.

Polypropylene

• Pros: It is lightweight, does not absorb water (it floats), and is generally cheaper.
• Cons: It has a lower breaking strength and a lower melting point. It also feels a bit more plastic to the touch.
• Best Use: Light-duty straps, tote bag handles, and gear that won’t be supporting critical weight.

Nylon

• Pros: incredibly strong, soft hand-feel, and very high abrasion resistance. This is the military standard.
• Cons: It absorbs water (getting heavier when wet) and can stretch slightly under heavy loads.
• Best Use: Backpack shoulder straps, climbing gear, heavy load-bearing applications.

The Seatbelt Variant: You will often see “seatbelt webbing” listed. This is usually polyester or nylon woven to be thinner, smoother, and shinier than standard tactical webbing. It is exceptionally strong but slippery. If you use this, make sure your buckles have teeth or a strong grip; otherwise, the smooth webbing will slide right through the adjuster.

2. Hook and Loop

We all call it Velcro, but that is a brand name. The generic term is “hook and loop.” When buying this for tactical or outdoor gear, you need to look at the cycle life and the peel strength.

• Standard Sew-On: This is what you find at a craft store. It works fine for a jacket pocket, but mud and dirt will eventually clog it.
• Mil-Spec: Military specification hook and loop is designed for thousands of cycles without losing grip. If you are making tactical gear, accept no substitutes.
• Adhesive Backed: Be very careful here. If you are sewing, do not buy adhesive-backed hook and loop. The glue will gum up your needle, snap your thread, and ruin your sewing machine’s timing. Only buy sew-on (non-adhesive) for stitched projects.

3. Binding Tape

Have you ever looked at the raw edge of a piece of fabric inside a high-end bag and noticed it is wrapped in a smooth, folded ribbon? That is binding tape. It finishes the raw edges so they don’t fray.

• Grosgrain Ribbon: This is the industry standard for binding seams. It is rigid, strong, and has a ribbed texture. It is excellent for structural integrity.
• Bias Tape: This is cut at a 45-degree angle to the fabric grain, meaning it stretches. You need this if you are binding a curved edge (like a rounded pocket). Grosgrain will wrinkle on a curve; bias tape will flow with it.

4. Elastic

Elastic is tricky because you can’t feel the tension through a computer screen.

• Braided Elastic: This has parallel ribs running the length of the elastic. It narrows when you stretch it. It’s good for casings (like a waistband), but it loses its integrity if you sew through it.
• Knitted Elastic: This is softer and doesn’t narrow when stretched. You can sew directly through it without destroying the elasticity.
• Woven Elastic: The heavyweight champion. It is thick, strong, and often used for heavy-duty applications like suspenders or ammo loops.

5. Hardware Compatibility

This is where the math comes in. If you buy 1-inch webbing, you might assume you need 1-inch hardware (buckles, tri-glides, D-rings). Usually, yes. But not all 1-inch measurements are created equal.

Some thick mil-spec webbing is actually slightly wider than one inch, or significantly thicker. If you buy a cheap plastic buckle with a narrow tolerance, you will fight tooth and nail to feed that thick webbing through the slot.

Pro Tip: If you are buying heavy-duty nylon webbing, look for “Mil-Spec” hardware. These are designed with slightly wider tolerances to accommodate the thicker tactical materials.

6. Do Not Ignore IR Compliance

If you are just making a backpack for hiking, this doesn’t matter. But if you are building gear for military, law enforcement, or serious hunting applications, you need to check if the narrow goods are IR-compliant.

Standard dyes reflect infrared light differently from the natural environment. Under night vision goggles, a non-compliant black strap might glow bright white, making the wearer a beacon. IR-compliant materials are treated to blend in under night vision. It costs a little more, but if the end-user operates at night, it is a non-negotiable safety feature.

Buy the Best, Cry Once

Narrow goods are usually the cheapest part of your bill of materials, yet they are the most critical for function. Saving fifty cents on a yard of webbing isn’t worth it when your shoulder strap snaps three miles into a hike.

Read the specs. Know the difference between nylon and polypropylene. Match your hardware to your material weight. If you build the skeleton right, the rest of the project will hold together for the long haul.
