    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.

MTN Silicone & ultra light insect mesh

Service by RIPSTOP is faultless.
Materials were purchased for making a tent.
MTN Silicone is very strong but extremely slippery to work with.
The ultra light insect mesh is surprisingly tough but almost impossible to work with.
Lots of patience seems to be needed when working with those materials.
Despite the level of difficulty working with these materials, I would buy them again for their superior performance.

That is the love/hate relationship with making lightweight shelters. The fabric required for all of these projects tends to be slippery because of the waterproof coating. Sewing with a piece of newspaper or tissue paper behind it tends to add extra grip. Try that next time!

So lightweight!

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

Thanks for leaving a review Hannah! We'd love to see what you made with the 1.1 oz MTN Silnylon 6.6! Be sure to tag us in photos on social media. :)
