    The MEMBRANE  sil line was developed with one goal in mind - create the lightest, most waterproof fabrics on the market

    Same silpoly benefits of lower water absorption (i.e. no sagging) and increased UV resistance, but in a waterproof textile that's 15-30% lighter than traditional lightweight coated nylon/polyester fabrics.

    MEMBRANE Silpoly is the ultralight version of our MEMBRANE silpoly line of ultralight coated materials. At a finished weight of just 0.93 oz/yd 2, it is the lightest waterproof polyester textile available. The material features the following:

    • Custom woven, high-thread count 15D polyester
    • Plain-weave construction
    • High-quality sil/PU coating on each side

    MEMBRANE Silpoly is best for situations where you want the lightest possible waterproof fabric outside of Cuben Fiber. Lower water resistance than the PU4000 version, but ~15% lighter. 

    A premium material for all projects requiring an extremely lightweight, waterproof textile. Common applications include tarps, tents, ponchos, gear sacks, pack covers, etc.

    *Note: this fabric is the exact same on each side. If seam sealing, we recommend using a 100% Silicone sealant such as Sil-Net

Great end product

The end result was great! In general I was hoping the directions would have been easier to follow, but all in all, it worked out well. With my configuration it ended weighing 16 oz with all required cordage and stuff sack.

Thanks for your review Luke! For future projects, feel free to reach out to us, we're always here to help!

Rbtr is just the best

Every time I order material from them it comes super fast, exactly how I ordered, and is extremely high quality. This membrane silpoly is so lightweight and packable, yet very easy to work with. I cannot believe with a little effort you can get a 12oz, 10’x12’ tarp for $65. I have not tested the waterfroofing yet, but thank you RBTR for making this possible and I will update when it has been used in a rainstorm, I have complete confidence that it will hold up to whatever I put it through

Thanks so much for your kind review and for being a customer Evan! MEMBRANE Silpoly is awesome for tarps, we can't wait to see how it turns out. Here is a link if you'd like to share photos with us https://forms.gle/b9GB5qYXrtp2bdp96

Must have rain fly fabric

My latest tent is a free standing double wishbone 2 person tent with removable rain fly. The Membrane rain fly only adds a out 8oz to the total 39.75oz total weight. It is stayed waterproof in light rain so far but I can't comment on sustained downpours. This material is easy enough to sew but being slippery makes large sections a bit of a chore to get beautiful rolled seams. Can't wait for RSBTR to get their new DIY gallery up and running. Even with submitting my projects on the Google form I have yet to see them shared.

Thanks so much for your review David! MEMBRANE silpoly is awesome for tents and tarps. We would love to see photos of your freestanding tent! Here is a link to share photos if you'd like, https://forms.gle/Vvm8pAGA4Q7EiHDm6

Perfect material for a rain skirt

I decided to use this material to make a rain skirt. It worked out perfectly. Didn't have any issues sewing it, although I did use tissue paper as a backing when I first started sewing the rolled hem at the corners.

Thanks so much Tammie! We're glad you found the material easy to sew, the tissue paper trick is a super helpful for working with thin fabric! Thanks for sharing the photo as well, we love it!

Just what I wanted

This is the perfect material for the tarp I am making. It is wonderful to be able to order just the quantity needed. And there was a great variety of materials to choose from.

MEMBRANE Silpoly is a go-to fabric for tarp making!! We're glad you were able to find exactly what you needed. Let us know if you have any questions about creating, we're here to help!
