    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

Just right !

So light and soft ! It hasn't rained here in quite some time so I held it under the faucet and no water got through. Nice !

Great product for window coverings

I had a cold draft in my bedroom but didnt want to put in heavy fabric. I used this and it was perfect. I sewed rings at the top and attached to my ikea rail. Prrfect. Warmer.
