  • The MEMBRANEsil 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

MEMBRANE silpoly 1.1oz

My first purchase from Ripstop By The Roll.
I bought 7 yards of MEMBRANE silpoly0.93oz for a tarp project and was expecting a huge package...... Oh-boy, when a really small envelope arrived in super fast time I thought had made a mistake on my choice of material. This material is super strong and really light-weight, It's also really slippery.
So far I'm super stoked that my project is going to be really light weight and robust as a 4 season solo tarp/tent.
Peoples reviews / tips and tricks and videos from this site have been a GOD send as a first timer to MYOG.
Highly recommend this product.

Thanks so much for the review and for being a customer Alan! We would love to see your finished tarp, be sure to tag us on social media!

Not bad for 2nds.

First off I hate sewing this fabric. It is challenging to sew. Its so damn slippery and thin. Be prepared to pin this every 6 inches or so. Thats not really a fault of the product, just the nature of ultralight waterproof fabrics.

The only flaw I saw was there was some fine cardboard dust or some other contaminant embedded in the waterproof coating. Its hardly noteworthy and you have to really look at it to notice.

This stuff is pretty tough for its weight. I used it to make a bivvy. I like the end product, but sewing this was borderline torture
