There is a unique and profound satisfaction that comes from adventuring with gear you’ve made with your own hands. Creating your own backpack, tarp, or hammock allows you to build a piece of equipment that is perfectly tailored to your specific needs, often at a fraction of the cost of its retail equivalent. But for anyone in the “Make Your Own Gear” (MYOG) community, the journey begins not with a sewing machine, but with a critical decision: choosing the right fabric.

The success of your entire project hinges on this single choice. The vast world of modern technical textiles is incredible, but it can also be intimidating. Choosing the right material for outdoor gear is the foundational step that will determine whether your finished piece is a durable, high-performance workhorse or a disappointing failure. Understanding the properties of these advanced fabrics is the key to a successful build.

If you’re ready to start your next project, here’s a guide to the key things you need to consider when selecting your materials.

First, Learn the Language of Technical Fabrics

Before you can choose the right fabric, you need to understand what the specifications actually mean. Here are a few of the most important terms you’ll encounter:

• Denier (D): This is a measurement of the thickness of an individual fiber. A higher denier number, like 500D or 1000D, indicates a thicker, heavier, and generally more durable and abrasion-resistant fabric. A lower denier, like 20D, indicates a very lightweight, thin fabric.
• Waterproof Rating (Hydrostatic Head): Measured in millimeters (mm), this tells you how much water pressure a fabric can withstand before it starts to leak. A rating of 1,500mm is considered waterproof, while a high-end tent or rain jacket might have a rating of 10,000mm or more.
• Tear Strength: This measures a fabric’s resistance to tearing after it has been punctured. This is a crucial spec for lightweight items like tarps and hammocks, where a small hole could otherwise quickly turn into a massive rip.

Match the Fabric to the Mission

The “best” fabric is always the one that is best suited for the specific project you are building. You wouldn’t build a heavy-duty backpack out of the same material as an ultralight tarp.

• For Backpacks: Your primary concerns are abrasion resistance and durability. You need a fabric that can handle being scraped against rocks and set down on rough ground. Look for high-denier fabrics like CORDURA® (typically 500D or 1000D) or laminated fabrics like X-Pac, which offer an excellent blend of strength, low weight, and waterproofness.
• For Tarps and Tents: For your shelter, the most important properties are waterproofness and low weight. The two main choices are Silnylon and Silpoly. Both are polyester or nylon fabrics coated with silicone. Silpoly has the advantage of not stretching when it gets wet, meaning your tarp won’t sag overnight in the rain.
• For Hammocks: Here, you need a fabric that is lightweight but has a very high tear strength and is comfortable against the skin. A ripstop nylon with a high thread count is the classic choice.
• For Clothing and Insulation: For an insulated jacket or a quilt, you’ll need a very lightweight, down-proof, low-denier nylon or polyester to serve as the shell fabric.

Don’t Forget the Supporting Cast: Hardware and Thread

The most durable fabric in the world will fail if the seams that hold it together blow out. The quality of your thread and hardware is just as important as the fabric itself.

• Thread: Always use a high-quality, UV-resistant polyester thread for any gear that will be used outdoors. Nylon thread can lose strength when exposed to sunlight over time.
• Zippers: Stick with reputable, time-tested brands. YKK is the undisputed industry standard for a reason. Make sure to use a water-resistant zipper for applications like rain gear.
• Buckles and Hardware: Again, stick with trusted brands. High-quality plastic buckles and hardware will remain strong and reliable in cold temperatures, while cheap, off-brand hardware can become brittle and break when you need it most.

By taking the time to research your materials, match their properties to your specific needs, and invest in quality components, you can create a piece of custom gear that will perform flawlessly and last for years of camping adventures.
