    The Mountain Series is quite simply a collection of the highest performance fabrics/materials on earth. If you're searching for the best, this is it.

    Our 1.1 oz MTN Silnylon 6.6 is designed to be nothing short of the lightest, strongest, most waterproof Silnylon on the planet. 

    We start with a sheet of super strong 30D Nylon 6.6 yarn, add a ripstop grid, then finish with the highest quality 100% silicone coating known to man. 

    The result is a Silnylon with insanely high tear strength, > 3000 mm waterproof rating, and finished weight of ~1.5 osy. 

    The 1.1 oz MTN Silnylon 6.6 is a great fit for projects/products that require the absolute best combination of weight, durability, strength, and long-term waterproofing.

    Typical applications include tarps, tents, ponchos, gear sacks, pack covers, or any application where high-performance, waterproof/windproof fabric is needed.

So lightweight!

I LOVE this fabric. It’s absolutely worth the price. Very lightweight and durable. Slightly more stretchy than silpoly. Very waterproof.

Thank you kindly Jeanne! We're so glad that you are satisfied with our products and services, Happy Making!


Amazing material! Just made a tarp for backpacking out of the MTN Silnylon material. Exactly the the material I need. Very light weight, compacts beautifully. Ripstop-By The Roll is awesome. With all their galleries, instructions, and parts available, you can't go wrong.

Thanks for your review Jake! We're happy to hear you are pleased with the 1.1 MTN Silnylon for your backpacking tarp! Let us known if you have any questions about future projects, we're here to help!

Sooo slippery

Does truly appear to be an extremely high quality material. I made a rain skirt from it and it sheds the rain so quickly that it doesn't even bead up. The rain just slippery slides right off before getting a chance to stick. I would buy it again for this application in a heartbeat.

Thanks for taking the time to leave us a review George! We're glad to hear this 1.1 oz MTN Silnylon was the perfect fabric for your rain skirt!
