DIY / MYOG Supplier Master List

Interested in making your own gear? You're gonna need some supplies and materials.  What follows is a comprehensive list of the best DIY suppliers around. With these links, you can get your hands on anything you'll need to make your own gear: silnylon, ripstop nylon, x-pac, cuben fiber (now dyneema), thread, buckles, webbing, cord, cord-locks, and so much more. **Cue Jurassic Park intro music** Welcome to the world of DIY.

I've separated the data into two tables below. The first shows detailed breakdowns of what I believe to be the top 5 DIY suppliers around currently. The second table features all other DIY suppliers that I know of with a brief description. If you don't see a certain DIY supplier that you think should be featured, let me know in the comments! Both tables are searchable, though I don't list out every fabric these places carry. That would make for far too long a list. I did try to mention the specialty materials these sites carry though, so you may be able to find what you are looking for.  If you're wondering about the tools and gear I use to make my projects,check out this list I put up.

The Top 5 DIY suppliers in detail:

DIY Supplier Link Fabrics? Waterproof fabrics? Insulation? Cordage/Webbing? Components/Accessories/Buckles Specialties Notes
Ripstop By The Roll Perhaps one of the best offerings around. An appropriately large selection, that is easy to navigate. Silnylon and Cuben, among others Down & Synthetic. Amsteel, zing it, shock cord, and more. All the things Custom printed outdoor fabrics and webbing. Some of the lightest materials available. My all time favorite supplier. Unlike most others, Kyle has pretty much anything you need, and a modern/functional website to boot. A++
Dutchware Gear Many awesome exclusive fabrics among others. The Argon 67 makes a great lightweight quilt. Also Tyvek. Some really cool silnylons, cuben, and some hybrids. Down, Synthetic, Reflectix. More cool exclusive stuff and the usual supplies too. Everything plus some really unique components. Dutch himself makes some great hardware too. Custom hardware and many things that just can’t be found anywhere else. Plus stuff like: carbon felt, carbon fiber poles, Kydex, and other specialty materials. I have always loved Dutchware. It’s one of those sites that is fun to browse and it’s interesting just to see what boundaries Dutch is pushing. Check out their gear and FOOD!
Rockywoods The largest selection of fabrics by far. Unique offerings like: wool, grid-fleece, heat bonded fabric, canvas, and too many more to even think about. The usual suspects, waterproof breathables, and many more. Sort of: Thinsulate and Polartec Fleece. Most anything you’ll need, but it’s frustratingly difficult to navigate the site and find what you need. The usual, but again, very hard to navigate. Having everything you need plus some really out there fabrics with uses far beyond backpacking and hiking. This is the best place for X-pac material that I know of. I’ve said it before and I’ll say it again, Rockywoods could really use an update. They have such great supplies, but the website feels so difficult use.
Quest Outfitters A wide array of all outdoor fabrics, mesh, fleece neoprene and much more. Most anything you’d ever need, many WPB’s, X-Pac, and silnylon. Goose down and multiple synthetic options. Everything you need and more. Great selection. All the classic hardware and some new components too. Their gigantic collection of outdoors materials. Tent poles. Great Remnants. Great supplier overall. They can be a one-stop shop for many projects. The site is a little dated and could use more fabric pictures.
DIY Gear Supply Plenty of ripstop options, gore-tex, and others. Silnylon, Gore-tex, and others. (Sometimes X-Pac) Synthetic and sometimes down. Amsteel, Glowire, shock cord and more. All of the above. Sometimes they have foam for pack straps and hip belts in stock. Their 2nds offer a great cheap option for silnylon. And they always seem to have the one thing you need. The (Modern) Classic DIY supply site. Scott has always shipped fast and accurate. Lately, it seems some materials don't get restocked as often as they once did.
