    The 2nd generation of our silicone double coated 1.1 oz polyester ripstop (silpoly). This fabric is coated with a silicone/PU layer on each side and is waterproof/non-breathable.

    In addition to  excellent  waterproof/windproof characteristics, Silpoly offers lower water absorption  and increased UV resistance compared to Silnylon.  Particularly useful in outdoor applications to minimize  sag/stretch when wet and color fade over time.

    Great for projects such as tarps, tents, ponchos, gear sacks, pack covers, or any application where durable waterproof/windproof fabric is needed.

    NOTE  - Colors with a reduced price of $5.25 /yd are being  phased out of inventory. Once sold out, they will not be restocked

Nice fabric

Fabric is bright and strong. Ive been making a bivvy and making joins with silicon and it works a treat. A little thinner than i was thinking but thats my fault nothing to do with RBTR

Thanks James! We're glad you love the color options of the 1.1 oz Silpoly, makes for a great bivy sack. We'd love to see photos of your creation be sure to tag us on social media!

Great Material, Color is not what was expected

I have zero complaints about the material. Very lightweight, no flaws whatsoever. The only issue is the "Coyote" color is not the typical coyote brown used in other applications. This not necessarily a bad thing in my case but beware if that's what you're looking for. I would say the "Coyote" color that I received on two orders is more like a dark chocolate color/coffee color.

Hey David! Thanks for your honest review. We're sorry that the color wasn't quite what you were expecting. We can offer samples in the future to make sure the color is exactly what you are looking for. If you have any questions, feel free to reach out to us at

Great product

Item as described. Worked perfectly for my needs.

Thanks for the review Andrew! We're glad this 1.1 oz Silpoly is working well for your projects!

Great Value for the Cost!

I purchased the 1.1 oz Silpoly fabric. It was perfect for my project of making a tarp. The company communicated well with me to let me know when to expect delivery.

Thanks for the review, Deborah! This is a great fabric for a DIY tarp, we are glad you are happy with your fabric choice! Let us know if you have any questions about future projects, we're here to help!

1.1 Silpoly

IMO it's great go to option for bridging the gap between ultralight packable and durable. Packs down small and is robust enough (in my experience anyway). Once I got the hang of working with the slippery stuff, it's good going.
I'm a big fan of this fabric.

It's one of our favorites as well at RBTR! We'd love to see some of your projects, be sure to tag us on social media!
